| 17:48.44 | d-lo | yessir. Done did it already :) |
| 17:48.49 | brlcad | awesome |
| 17:53.41 | brlcad | Ralith: jdoliner: filled yours out too I hope? |
| 17:58.59 | jdoliner | i did indeed |
| 18:02.07 | ``Erik | and d'lo is gone, saw him driving out as we got back from lunch (green turtle) |
| 18:03.04 | brlcad | he answered |
| 18:04.00 | ``Erik | yeh, but he's out now, 'sall I'm sayin' :) |
| 18:04.23 | ``Erik | he was probably surprised to see me driving a 4d car |
| 18:11.24 | Yoshi47 | what the bext rendering technic i should use for my bearing, its done! |
| 18:11.28 | jdoliner | it's a uniquely depressing experience to discover a prototyped opennurbs function isn't actually implemented |
| 18:16.07 | brlcad | Yoshi47: great, congratulations! |
| 18:16.17 | brlcad | Yoshi47: you might want to try running "rtwizard" |
| 18:16.26 | brlcad | it has embedded help, various render styles |
| 18:16.27 | Yoshi47 | brlcad, thanks, don't ask me how many hours so far! |
| 18:16.35 | Yoshi47 | brlcad, ok i'll try that out |
| 18:16.40 | brlcad | otherwise, I tend to like rt rendering with an rtedge overlay |
| 18:17.22 | brlcad | tweaking shader properties, maybe adding textures and creating custom lights give the best result |
| 18:17.48 | Yoshi47 | brlcad, i get this ./rtwizard: line 26: exec: bwish: not found when trying exec rtwizard |
| 18:18.19 | starseeker | brlcad: just curious - is there any sort of "minimal" opengl scene graph setup that's smaller and lighter weight than Ogre/OpenSceneGraph? |
| 18:18.19 | brlcad | o.O |
| 18:18.30 | brlcad | Yoshi47: you haven't installed brl-cad? |
| 18:18.46 | brlcad | nice example rendering: http://brlcad.org/tmp/goliath2.png |
| 18:18.54 | Yoshi47 | yep, svn install this morning, then autogen.sh -> ./configure -> make -> make install |
| 18:19.07 | brlcad | then why's it saying ./rtwizard |
| 18:19.10 | starseeker | is /usr/brlcad/bin in your path? |
| 18:19.30 | brlcad | oh, hah, are you actually cd'd into /usr/brlcad/bin? |
| 18:19.43 | Yoshi47 | brlcad, yeah but i forgot to make symbolic links... |
| 18:19.45 | Yoshi47 | one sec |
| 18:19.56 | brlcad | shouldn't need to make any symbolic links :P |
| 18:20.01 | Yoshi47 | i installe dinto /opt |
| 18:20.10 | brlcad | still shouldn't need to make any symbolic links :P |
| 18:20.22 | Yoshi47 | umm well im cd /opt/brlcad/bin/ |
| 18:20.30 | Yoshi47 | then tried rtwizard. |
| 18:20.34 | Yoshi47 | bwish is there |
| 18:20.35 | brlcad | yeah, that's just a funny way to run things |
| 18:20.46 | brlcad | right, but how's it supposed to know bwish is there |
| 18:20.57 | brlcad | it's not like it knows it needs to run ./bwish because you ran ./rtwizard :) |
| 18:21.10 | Yoshi47 | from my path... |
| 18:21.14 | brlcad | it just runs "bwish" |
| 18:21.28 | Yoshi47 | right |
| 18:21.39 | brlcad | what happens if you just run "rtwizard" |
| 18:22.12 | Yoshi47 | same thing |
| 18:23.02 | brlcad | if you run "bwish", what happens? |
| 18:23.22 | Yoshi47 | bwish> |
| 18:23.37 | Yoshi47 | well i ran ./bwish |
| 18:23.41 | brlcad | heh |
| 18:23.42 | brlcad | dude |
| 18:23.58 | brlcad | "rtwizard" is not "./rtwizard" |
| 18:24.18 | brlcad | nor is "bwish" "./bwish" :) |
| 18:24.30 | brlcad | your path isn't set |
| 18:24.42 | Yoshi47 | i guess i don't folly understand the principle yet, kinda do but not all the way |
| 18:24.52 | brlcad | you have to set your path for binaries to be found |
| 18:24.56 | Yoshi47 | brlcad, thats what i figured |
| 18:25.24 | brlcad | you're fine when it's a stand-alone binary, but not when it's something that relies on other resources |
| 18:25.37 | brlcad | that goes for any application, not just brl-cad tools |
| 18:26.07 | brlcad | export PATH=/opt/brlcad/bin:$PATH |
| 18:26.10 | brlcad | for bash at least |
| 18:26.30 | Yoshi47 | got it |
| 18:26.34 | Yoshi47 | thanks |
| 18:27.17 | Yoshi47 | how long should it take to load |
| 18:30.31 | brlcad | depends on how fast your system is, but there should be a progress meter |
| 18:30.41 | brlcad | unless you see it spit out an error |
| 18:31.42 | Yoshi47 | no it was a seperate window 40% Megawidgets Packed |
| 18:31.47 | Yoshi47 | still can go on though |
| 18:35.29 | brlcad | if it's not moving, it's stalled on something |
| 18:37.15 | brlcad | ~seen Ralith |
| 18:37.18 | ibot | ralith is currently on #brlcad, last said: ':P'. |
| 18:37.21 | Yoshi47 | no i just close it and i can move on |
| 18:37.37 | brlcad | should have prodded ralith over the weekend |
| 18:41.42 | Yoshi47 | what type of file is outputted from the wizard? png or jpeg |
| 18:42.11 | brlcad | well definitely not jpeg because we don't support any lossy formats |
| 18:42.17 | brlcad | but either pix or png |
| 18:42.18 | Yoshi47 | good |
| 18:42.32 | Yoshi47 | outputs a corrupted file png |
| 18:42.35 | Yoshi47 | 3MB big |
| 18:42.48 | starseeker | hmm - this is LGPL and looks like about 1M in size - wonder if it's any good? http://plib.sourceforge.net/ssg/index.html |
| 18:42.49 | brlcad | are you sure it's a png? |
| 18:42.58 | brlcad | i'm betting it's a pix |
| 18:43.05 | Yoshi47 | how do you specify i just ending the file name with png |
| 18:43.12 | brlcad | ah, heh |
| 18:43.18 | brlcad | yeah, that won't do it |
| 18:43.28 | brlcad | if it has no options to say "png", then it's definitely a pix file |
| 18:43.40 | brlcad | pix are raw first quadrant image files |
| 18:43.45 | brlcad | you can run pix-png to convert it |
| 18:44.08 | Yoshi47 | ok i'll try that |
| 18:44.08 | brlcad | (pix-png -n 1024 -w 768 < file.pix > file.png |
| 18:44.16 | brlcad | for a 1024x768 image of course |
| 18:44.32 | brlcad | it's a raw image, so you have to tell it what the dimensions are |
| 18:45.31 | starseeker | hrm. maybe not so small - needs some plib utility libraries |
| 18:45.32 | starseeker | nuts |
| 18:46.45 | brlcad | hm? que? |
| 18:46.51 | starseeker | er, sorry |
| 18:47.18 | starseeker | just looking around to see if there is some kind of small scene graph library we could use in archer without including all of Ogre/OpenSceneGraph |
| 18:47.18 | brlcad | working in *any* scene graph is going to be about the same amount of work, regardless of how complex it is |
| 18:47.39 | brlcad | most of the work is on the archer/mged/libdm side of things |
| 18:48.10 | starseeker | nods. Figured, but we probably can't justify pulling everything needed for Ogre just to make archer's wireframe behave better |
| 18:48.31 | starseeker | was hoping there was something small that could be used just for Archer, prior to the new GUI work |
| 18:49.17 | brlcad | sure we could -- if it improves things, then it's progress -- an orge libdm interface would be very useful |
| 18:49.56 | starseeker | but Ogre + deps would be a great deal larger than even opennurbs or docbook - wouldn't that be too much to pull in? |
| 18:50.18 | starseeker | at least, without something new and spectacular in the UI department? |
| 18:50.21 | brlcad | it is a lot for a small gain, depends how well it worked |
| 18:50.47 | brlcad | if it was perfectly seamless and fully integrated, I think it'd be worth it - but that's a big 'if' |
| 18:50.53 | starseeker | nods |
| 18:51.26 | starseeker | I should explore the libdm setup and the new rtgl work, might be a good starting point |
| 18:51.55 | brlcad | could still create an ogre libdm as a dev project, assume a system-installed ogre with an interface that is all or nothing on/off |
| 18:52.05 | brlcad | yeah, was going to say that |
| 18:52.19 | brlcad | the way rtgl is now is far from ideal (and actually a bit of a problem) |
| 18:52.52 | brlcad | libdm's api was originally constructed around displaying polygonal line segments |
| 18:53.06 | starseeker | winces |
| 18:53.23 | starseeker | and I'm guessing we can't monkey with that API anytime soon? |
| 18:53.26 | brlcad | it needs to be more scenegraphish where you either set up rendering callbacks (probably ideal) or expand the api to more general entities |
| 18:53.33 | brlcad | sure we can |
| 18:53.53 | starseeker | wouldn't we be breaking external code? Or does nobody use the dm directly? |
| 18:54.04 | brlcad | libdm is fair game to change, so long as the archer and tcl megawidgets continue to "work" |
| 18:54.14 | starseeker | ah :-) |
| 18:54.18 | brlcad | the tcl megawidgets are used externally |
| 18:54.59 | starseeker | hates to expose his ignorance but had better - "rendering callbacks" refers to ? |
| 18:55.12 | brlcad | the src/tclscripts/lib entities in particular |
| 18:56.02 | brlcad | okay, rendering callbacks are just like logging callbacks (if that helps) |
| 18:56.11 | Yoshi47 | why is there little tiny dots here and there on my images? |
| 18:56.23 | brlcad | but consider if you had something you wanted to draw, like a bunch of line segments that need to get sent to opengl |
| 18:56.35 | brlcad | Yoshi47: screenshot? |
| 18:56.45 | Yoshi47 | one sec. |
| 18:57.20 | brlcad | a direct approach would be to have a place where your application code compiles a list of line segments, and then sends those to libdm saying "draw this" .. an immediate mode of sorts |
| 18:58.18 | brlcad | a callback approach would be more like telling libdm, "call this function when it's time to draw" and then that function dispatches the things to be drawn in that callback function using a context libdm provides |
| 18:58.48 | Yoshi47 | brlcad, http://ej.nijenhuis.pixi.me/v/CAD/ |
| 18:59.31 | brlcad | doesn't matter much for somethign simple like rendering line segments, but can be a big deal if you want to support arbitrary rendering methods (like ray-tracing or scene graphs) instead of just some subset of geometric entities |
| 19:01.50 | starseeker | brlcad: OK. Is there a pre-existing API you would like libdm to emulate? |
| 19:06.09 | brlcad | I'd just solve the problem as you go along -- it's pretty easy to tell where/when things go wrong because you end up with #ifdef code outside of libdm |
| 19:06.10 | *** join/#brlcad talcite (n=Matthew@bas1-toronto21-1242460322.dsl.bell.ca) |
| 19:06.35 | starseeker | nods |
| 19:07.19 | starseeker | when the rubber hits the road, what did you want to do about Ogre's build system? do we assume cmake is available and trigger it with autoconf? |
| 19:07.34 | Yoshi47 | is it how i rendered it, it also happens when rendering inside wged. |
| 19:07.51 | starseeker | (e.g. with Ogre living in src/other/ogre ...) |
| 19:11.55 | brlcad | for the main brlcad line, I'd assume ogre was system installed like X and leave it at that for now -- you get another dm if you don't have it |
| 19:12.07 | brlcad | we just make sure we have it when it comes time to release |
| 19:12.24 | starseeker | OK |
| 19:13.53 | Yoshi47 | well since im done with bearing for now, back to my imported dxf shape, how should i extrude it? |
| 19:18.54 | talcite | ahaha the review request has been posted! https://bugzilla.redhat.com/show_bug.cgi?id=518949 |
| 19:19.21 | brlcad | Ralith: wake up dude :) |
| 19:26.48 | ``Erik | Yoshi47: it'd be neat to see render_balls done with perspective mode and some scene around the object :) |
| 19:28.12 | Yoshi47 | ``Erik, i have to make the scene first, which leads back to my question 4 lines up... by the way how is my drawing? bad or not too bad for 3 days at it? |
| 19:28.43 | ``Erik | drawing? |
| 19:29.58 | Yoshi47 | ``Erik, what would you like? sorry |
| 19:30.18 | ``Erik | the model looks cool, I tend to just make a 'half' with a checkerboard shader and make the background color 'blue', so it comes out like http://brlcad.org/gallery/s/renderings/primitives/niceballs.png.html |
| 19:30.26 | ``Erik | but just cuz it's really easy and quick *shrug* |
| 19:31.36 | ``Erik | could always concat it into like the bldg391.g or cornell.g just to get some real surroundings :) |
| 19:31.43 | Yoshi47 | ``Erik, what degree perspective on it? |
| 19:32.08 | ``Erik | play with it? between 0 and 90, probably someting like 60ish would be good? |
| 19:32.32 | ``Erik | (er, 0 and 180) |
| 19:32.32 | Yoshi47 | ``Erik, so you have no answer my extruding? |
| 19:32.38 | ``Erik | no, I don't :( |
| 19:33.02 | ``Erik | maybe brlcad knows, but he's off napping or playing with his hello kitty dolls again or something |
| 19:33.04 | Yoshi47 | ``Erik, umm, i would figure more people would be extruding stuff on a regular basis. |
| 19:33.35 | ``Erik | <-- tends to stick to lower level stuff, doesn't know squat about modelling :) |
| 19:34.03 | Yoshi47 | ``Erik, well someones got to do the lower stuff, i know i can't |
| 19:35.04 | brlcad | Yoshi47: those dots are floating point tolerance bugs where two faces are overlapping -- the boolean logic is ill-defined, a very old issue |
| 19:35.15 | ``Erik | has been thinking about replacing libbu's red/black tree with a generalized tree interface (callbacks in a struct) O.o |
| 19:35.32 | Yoshi47 | brlcad, umm ok, i guess nothing we can do |
| 19:36.00 | Yoshi47 | brlcad, you also don't have a answer about extruding? |
| 19:36.04 | brlcad | Yoshi47: you can eliminate the artifacts by restructuring the booleans, but it's usually easiest to just render larger and scale down |
| 19:36.21 | brlcad | the points are hairline floating point so they won't scale up with the image |
| 19:36.22 | ``Erik | or hypersample |
| 19:36.26 | Yoshi47 | brlcad, i'll keep in mind for the next render |
| 19:36.55 | brlcad | yeah, hypersampling should minimize it too -H4 or larger |
| 19:37.14 | brlcad | hasn't even read the question about extruding yet .. lots of threads goin :) |
| 19:38.15 | ``Erik | importing a dxf 'shape' is an iffy thing, we only handle triangle meshes from autocad, not anything like a 2d layout |
| 19:38.20 | ``Erik | I think |
| 19:38.27 | brlcad | as for 3 days at it .. newbie time scale .. that shouldn't have taken more than an hour or less |
| 19:38.46 | brlcad | i bet if you did it again, it'd only take a day now |
| 19:38.57 | brlcad | and then do it again, probably half a day |
| 19:39.07 | brlcad | fast falloff |
| 19:39.19 | brlcad | talcite: awesome! |
| 19:44.08 | Yoshi47 | brlcad, i bet i could do it under and hour now... |
| 19:45.27 | Yoshi47 | ``Erik, so what your saying im better off redrawing, shouldn't be too hard but a couple hours since i got like 4 extrusions to do... |
| 19:49.54 | CIA-28 | BRL-CAD: 03brlcad * r35692 10/brlcad/trunk/src/tclscripts/mged/help.tcl: note that the rotation values for clone's -b option are in degrees, as suggested by Yoshi47 on IRC. |
| 19:51.09 | brlcad | talcite: the floating point compliance problem is real, but I haven't yet seen it be an actual problem anywhere yet -- several platforms report that |
| 19:51.28 | brlcad | cross-compiling might have caused it even |
| 19:51.36 | talcite | oh ok. It just might be because I'm cross compiling in this case |
| 19:51.42 | Yoshi47 | brlcad, what does the CIA-28 mean? that the help will be updated or has been? |
| 19:51.44 | talcite | yeah. It didn't show up in native compiles |
| 19:52.21 | brlcad | starseeker: arbn is implicitly defined as the boundary enclosed by the surfaces resulting from those intersecting planes .. so yeah, implicit ;) |

| 20:05.15 | Yoshi47 | brlcad, cool |
| 20:07.18 | Yoshi47 | brlcad, im still having a hard time crasping the concept behind this, if i desing my extrusion a foot long how easy is it later on to extrude that to what ever lenght i would like? would OED work on it for changing the length and then that would push down to the primitive shapes? |
| 20:10.29 | brlcad | it should, but not sure I've heard of anyone try |
| 20:11.09 | brlcad | would be pretty simple to do an adjust or primitive edit to change the length given it's a simple vector |
| 20:15.04 | brlcad | adjust extrude1.s H {0 0 100} |
| 20:15.34 | brlcad | "get extrude1.s" will show all of his parameters |
| 20:15.56 | brlcad | note that's a low-level operation -- if you mess up, you're screwed |
| 20:16.27 | brlcad | it WILL let you make invalid geometry and then never let you mess with that object again (because it's invalid) .. so be careful, make a backup, etc |
| 20:17.23 | Yoshi47 | so if my extrusion is a region this should be possible too... |
| 20:17.32 | Yoshi47 | or even a group? |
| 20:17.47 | brlcad | your extrusion is not a region |
| 20:17.56 | brlcad | your region may contain/reference an extrusion |
| 20:18.43 | brlcad | that get/adjust example works on primitives |
| 20:19.06 | brlcad | the get on a combination/region/group is going to simply show you the objects they reference and any transformation matrices |
| 20:19.26 | Yoshi47 | ok but in order for me to get me extrusion shape i need to make multiple shapes and then put them in a region with -+u and then i have a region, can i change to whole region and all its children at once or just individual members |
| 20:20.08 | Yoshi47 | i think i'll just make my extrusion a foot long and then try it when im done, should be a good learning experience. |
| 20:20.54 | brlcad | using get/adjust, that's specific to primitives and per-object -- I'd suggest just trying an example of scaling down an extrusion in the same direction as it's H vector and it *should* modify the H after a push |
| 20:21.05 | brlcad | or leave it unpushed, shouldn't matter |
| 20:21.36 | Yoshi47 | brlcad, ok |

| 21:26.29 | Yoshi47 | remember most of the measurements but not all... |
| 21:47.37 | brlcad | so you lost the whole thing?? |
| 21:47.43 | Yoshi47 | brlcad, yep |
| 21:47.48 | Yoshi47 | i sad |
| 21:47.49 | brlcad | way to put that rework measurement to test :) |
| 21:47.59 | brlcad | you'd make a great case study about the learning curve |
| 21:48.02 | Yoshi47 | brlcad, yep, knock on wood |
| 21:48.28 | Yoshi47 | well i plan on doing it tomorrow, |
| 21:48.28 | brlcad | if you do recreate, please do share how long it takes... :) |
| 21:48.31 | Yoshi47 | so i'll time myself |
| 21:48.34 | brlcad | cool |
| 21:48.57 | brlcad | what's your fs? |
| 21:49.16 | Yoshi47 | i can't see it taking that long, most of my time was playing around with commands, especially that clone one... |
| 21:49.38 | brlcad | clone gave you trouble? |
| 21:49.41 | Yoshi47 | one sec got to ssh in i forget, |
| 21:49.44 | brlcad | (other than the rads/degs) |
| 21:49.55 | Yoshi47 | brlcad, a little had to figure that degrees thing out... |
| 21:50.02 | Yoshi47 | brl maybe 10mins on that |
| 21:50.38 | Yoshi47 | etx3 |
| 21:50.47 | Yoshi47 | i know there is an undelete for that right? |
| 21:50.59 | Yoshi47 | but have no clue how to work it or start using it |
| 21:51.03 | Yoshi47 | ext3* |
| 21:51.21 | brlcad | it's not exactly an undelete, but there is a way you can try to recover |
| 21:51.56 | Yoshi47 | well im willing... |
| 21:56.53 | CIA-28 | BRL-CAD: 03starseeker * r35693 10/brlcad/trunk/src/librt/primitives/nmg/nmg_brep.cpp: Start sketching out a way to get enough info for BREP surfaces out of NMG faces. |
| 21:58.32 | mafm | Yoshi47: http://www.xs4all.nl/~carlo17/howto/undelete_ext3.html |
| 21:58.34 | mafm | good luck |
| 21:58.37 | mafm | :) |
| 21:58.48 | Yoshi47 | mafm, ya im reading it already |
| 21:58.49 | brlcad | yeah, it's quite involved |
| 21:59.00 | Yoshi47 | brlcad, i think it will be faster to redraw |
| 21:59.27 | mafm | thinks undeleted and on-line defrag would be ext4's flagship features |
| 21:59.35 | mafm | yet none of those are available yet :/ |
| 22:00.16 | brlcad | you could probably find the .g file in a raw search of the drive -- our start of file marker is pretty specific |
| 22:01.28 | Yoshi47 | brlcad, how would one go about a raw search? |
| 22:02.31 | brlcad | something like: grep -a -5 "Untitled BRL-CAD Database" /dev/hdawhatever > output.bin |
| 22:02.46 | brlcad | might have to unmount the drive |
| 22:02.52 | mafm | I think that there are specific tools for that |
| 22:03.12 | mafm | searching for files still present, matching a pattern |
| 22:03.50 | brlcad | the trick is to find your title or some other easily findable content, then dump enough context around that marker, then manually strip out the rest with a hex edit |
| 22:04.42 | brlcad | that ext3grep tool is basically doing something similar, but walking the inode structure -- a raw grep or dd is much lower-level |
| 22:04.59 | CIA-28 | BRL-CAD: 03irpguardian * r35694 10/brlcad/trunk/src/libged/human.c: Fixed a problem where name holder variables were not being properly initialized. |
| 22:05.16 | brlcad | which should help finding a match whether it was in the journal or on the fs or memory cache or whatever |
| 22:07.17 | brlcad | should have had you post your .g somewhere to check it out :) |
| 22:07.37 | Yoshi47 | brlcad, yep |
| 22:08.06 | brlcad | and you're sure you didn't just sync it to a remote host.. hehe |
| 22:08.30 | Yoshi47 | nope i was going to sync from work to home but did the other way and with out update on |
| 22:22.16 | Yoshi47 | well shes searching... |
| 22:23.57 | brlcad | -5 probably isn't going to be enough, but the trick first is to just *find* the string, then expand the context until it matches the whole file |
| 22:24.04 | brlcad | then hex edit |
| 22:25.55 | Yoshi47 | i got freebsd burning to a dvd for my notebook right now |
| 22:25.58 | Yoshi47 | going to give it a shot |
| 22:26.12 | Yoshi47 | brlcad, install better be easy! lol |
| 22:27.42 | *** join/#brlcad louipc (n=louipc@archlinux/trusteduser/louipc) |
| 22:28.22 | Yoshi47 | i kinda don't want to find it too, i want to give that redraw thing a timing test. lol |
| 22:34.42 | Yoshi47 | brlcad, how big do you think my db would of been? .5mb 1mb 10mb? |
| 22:35.10 | brlcad | less than 1mb for sure |
| 22:35.31 | brlcad | probably not more than 2-4kb actually, but hard to say what junk you had in there ;) |
| 22:35.40 | Yoshi47 | i got a whole bunch of txt files back |
| 22:35.47 | Yoshi47 | from ralf |
| 22:35.59 | brlcad | did you set a title? |
| 22:36.15 | Yoshi47 | yep |
| 22:36.17 | Yoshi47 | 608Z |
| 22:36.19 | brlcad | you'll want to search a unique identifier |
| 22:36.55 | brlcad | yeah, that's not distinctive enough |
| 22:40.24 | brlcad | but... |
| 22:40.30 | brlcad | probably could find it with.. |
| 22:40.34 | brlcad | what was your grep? |
| 22:40.53 | brlcad | 'title[^[:print:]]608Z' should be pretty darn specific |
| 22:41.14 | Yoshi47 | i used http://projects.izzysoft.de/trac/ext3undel/ |
| 22:41.30 | Yoshi47 | but it return a dir i delete a while ago, i thinks it gone... |
| 22:41.44 | Yoshi47 | oh well, well just have to test our time theory out i don't mind too much |
| 22:41.55 | Yoshi47 | second time is always a charm |
| 22:42.13 | brlcad | try the /dev/hda grep in the background, just let it run overnight or something :) |
| 22:42.49 | brlcad | grep -a -10000 'title[^[:print:]]608Z' /dev/hda1 > output.bin |
| 22:43.25 | brlcad | or whatever you have that fs mounted as, ideally direct output to something not on /dev/hda1 :) |
| 22:43.35 | brlcad | -10000 should be plenty to capture the file |
| 22:44.31 | Yoshi47 | wouldn't that also capture the current one or both? |
| 22:44.39 | Yoshi47 | i guess both its grepping, duh |
| 22:45.03 | brlcad | yeah |
| 22:45.43 | Yoshi47 | here we go with fbsd |
| 22:45.54 | brlcad | you can test it with grep -a 'title[^[:print:]]608Z' yourfile.g | less |
| 22:45.58 | brlcad | should see the file ;) |
| 22:48.16 | Yoshi47 | 88G to search through |
| 22:49.23 | brlcad | yeah, that'll take a while :) |
| 22:49.53 | Yoshi47 | fbsd install kinda hard |
| 22:50.06 | brlcad | ? |
| 22:50.20 | Yoshi47 | oh, got to create a freebsd slice |
| 22:50.21 | brlcad | I didn't suggest you install fbsd did I? :) |
| 22:50.45 | Yoshi47 | brlcad, yes, im going to give it a try on my notebook since it needs a reload anyways, got a newer one |
| 22:50.47 | brlcad | I mean, love the OS, but one learning curve per week is pretty respectable ;) |
| 22:51.01 | Yoshi47 | brlcad, na i take on lots |
| 22:51.02 | brlcad | ah, fun |
| 22:51.51 | brlcad | fbsd desktop is not my first choice, but the dev environment, stability, and server features are top-notch |
| 22:52.31 | brlcad | course, last time I had it on desktop was many years ago, so not fair to speak to what their status is today |
| 22:53.03 | Yoshi47 | brlcad, what you use for desktop? |
| 22:53.50 | brlcad | mostly macosx these days, live in terminal windows and emacs most of the time ;) |
| 22:53.58 | Yoshi47 | ah |
| 22:54.43 | brlcad | gentoo and ubuntu have had a fairly strong presense in the past |
| 22:55.08 | brlcad | I have a real strong sweet spot in my heart for haiku as beos used to be a primary for several years for me too |
| 22:55.57 | brlcad | i give that a try a couple times a year it seems, report all the bugs I find and return back to something that just works |
| 22:57.15 | Yoshi47 | well the install sucks |
| 22:57.38 | Yoshi47 | maybe try arch |
| 23:10.18 | ``Erik | bah, things that just work are no fun :D |
| 23:11.41 | Yoshi47 | ``Erik, nice |
| 23:11.52 | Yoshi47 | don't worry i will most likely get fed up with it and return once again to gentoo |
| 23:12.14 | ``Erik | <-- is a bit of the masochistic "everything at once" mentality... currently doing common lisp, emacs, and web development all at once |
| 23:12.25 | ``Erik | being a vim/c/systems guy 'n all |
| 23:17.40 | Yoshi47 | so whats for supper |
| 23:19.24 | brlcad | oof, yeah.. haven't eaten today, damn |
| 23:19.37 | brlcad | hate it when I forget that |
| 23:23.37 | Ralith | brlcad: oh, thanks for the prod |
| 23:23.56 | Ralith | ``Erik: yay emacs! :D |
| 23:24.10 | Ralith | (yay CL too, for that matter) |
| 23:25.28 | Ralith | opens email, gets intimidated by volume of spam, and just goes to the site directly |
| 23:25.35 | Yoshi47 | umm whole wheat bread and peanute butter and chocolate sprinkles |
| 23:27.50 | brlcad | Ralith: they debated for a little while whether to fail the five students that didn't fill out their own evals... :) |
| 23:27.57 | Ralith | wups. |
| 23:27.58 | brlcad | I was a proponent of the "not fail" option |
| 23:28.00 | brlcad | :) |
| 23:28.03 | Ralith | thank you for that. |
| 23:28.23 | Yoshi47 | lol |
| 23:28.23 | Ralith | probably should have jumped to it the moment he saw the email subject line a couple days ago |
| 23:28.24 | brlcad | told them you were up until 5am coding :) |
| 23:28.39 | brlcad | and coding all weekend, so it sounded great ;) |
| 23:28.43 | Ralith | ^^ |
| 23:28.57 | brlcad | I should have nagged more too |
| 23:29.08 | brlcad | I didn't exactly send out my own reminder mails to everyone |
| 23:29.09 | Yoshi47 | at least someone happy ihave to go through time trials now! |
| 23:29.11 | brlcad | busy summer |
| 23:29.22 | brlcad | Yoshi47: hehe, cool |
| 23:29.33 | brlcad | but then that definitely will be a good note to send out ;) |
| 23:30.03 | brlcad | I'm really curious how long you'd take on redo now that "most" of the tool learning is out of the way, and there's some basic memorization in place |
| 23:30.58 | brlcad | for govt folks, they generally go through a week or two of hands-on modeling training and you can see (and measure) the rate increase pretty directly |
| 23:31.10 | Yoshi47 | im guessing under 2 hours,im going to setup a stop watch because i will get annoyig user(like me) asking questions... |
| 23:31.41 | brlcad | it's interesting to see that everyone is different, but most settle at some base "rate" of comprehension and retention .. there's definitely diminishing returns |
| 23:31.51 | Ralith | Yoshi47: don't do yourself a disservice; you haven't been annoying, on an absolute scale and certainly not compared to many of the people you can find on IRC. |
| 23:32.13 | brlcad | haven't been at all annoying, live for this stuff ;) |
| 23:32.16 | Ralith | if anything, it's nice to have newbies around learning the ropes; gives the place a feeling of activity. |
| 23:32.21 | Ralith | vivacity* |
| 23:32.31 | Yoshi47 | Ralith, thanks, hey q for you, will you be working on gui over the school year or not |
| 23:32.38 | Ralith | I certainly hope to |
| 23:32.49 | Yoshi47 | cool |
| 23:32.52 | brlcad | that would be awesome :) |
| 23:32.59 | Ralith | I've invested enough effort in this project that it would be depressing to just drop it. |
| 23:33.12 | Ralith | and I did, after all, start in on it because it was something I wanted to happen. |
| 23:33.13 | brlcad | and it's actually starting to approach usable |
| 23:33.23 | Ralith | ^^ |
| 23:33.34 | brlcad | it's converging towards lots of the same things archer needs under the hood libged-wise |
| 23:33.45 | Yoshi47 | good, well if you need any help on gui design i have a little bit of experience with that, i have helped with kiosk software, hey i should show you guys a picture of my kiosk design. |
| 23:33.49 | Ralith | I'm really looking forward to digging around the display list code and hooking that up |
| 23:33.55 | brlcad | which happens to be a lot of the same that search exec needs, and other priorities |
| 23:34.25 | Ralith | Yoshi47: oh? I'd certainly be very interested in any comments you have, even on the current highly incomplete state. |
| 23:34.57 | ``Erik | bah, I shoulda sent an email as well... allz I did was hollar at indianlarry :/ |
| 23:34.59 | Yoshi47 | Ralith, i will have yo learn how to downlaod and compile it, since i don't think its in svn |
| 23:35.06 | Ralith | Yoshi47: it's in SVN. |
| 23:35.22 | Yoshi47 | so if i compiled this morning it will be inthere? |
| 23:35.36 | Ralith | before I get to the fun stuff I still need to fix that damned input handling bug (the filter that sends input to camera control is for some reason getting events from *everything*, leading to strange behavior) |
| 23:35.45 | Ralith | Yoshi47: it's not part of brl-cad proper. |
| 23:35.52 | Ralith | build system isn't integrated |
| 23:35.58 | Ralith | different tree |
| 23:36.01 | Ralith | but it's still there. |
| 23:36.11 | Ralith | it's in rt^3/src/g3d |
| 23:36.45 | Yoshi47 | oh ok, well im busy right now but i will be sure to look at it soon hopefully. |
| 23:36.56 | Yoshi47 | i started learning qt4 this spring |
| 23:38.05 | ``Erik | "well... a certain kind of pirate, yes, we've been called that" "is there some kind of preschool program?" hehehe good old family guy |
| 23:38.56 | Ralith | Yoshi47: cool! Direct contributions are certainly welcome as well. |
| 23:39.11 | Ralith | that input bug, for example, is a qt-wrangling issue. |
| 23:39.38 | Yoshi47 | i don't know if im there, since it takes me long enough to get a basic app going, currently working FANO (food and nutrional organizer) |
| 23:40.16 | ``Erik | wait, did we lose 2? I thought we had 5 at the beginning |
| 23:41.14 | ``Erik | huh, only 4, *think* |
| 23:41.22 | ``Erik | wait, I remember now heh :) |
| 23:42.06 | CIA-28 | BRL-CAD: 03brlcad * r35695 10/brlcad/trunk/TODO: annotate a couple of the header tasks to make life easier |
| 23:42.29 | brlcad | ~seen madant |
| 23:42.31 | ibot | madant <i=cb7baf0f@gateway/web/freenode/x-a32eed164597bd06> was last seen on IRC in channel #brlcad, 52d 3h 20m 37s ago, saying: 'nothing more disastrous than non-cooperative softwares ;)'. |
| 23:43.45 | brlcad | ``Erik: ralith was d-lo's not indianlarry's |
| 23:44.16 | Ralith | observes that it might be advisable in the future to associate mentors based on timezone |
| 23:44.23 | ``Erik | hrm? I know... O.o |
| 23:44.32 | Ralith | not that this was a real problem thanks to IRC, but still. |
| 23:45.00 | ``Erik | a week or two ago, when one of the 'almost time' emails came out, I let indianlarry know it was approaching, so he could do his part... not so he could probe his student :) |
| 23:45.05 | brlcad | ahh |
| 23:46.49 | Yoshi47 | heres a link to my prototype Kiosk we call it the "Miniky" since the first one was different and way bigger" i do have another prototype after this one that has rounded corners, and a slide out filter tray and a little different design on the back, enjoy! |
| 23:46.50 | Yoshi47 | http://ej.nijenhuis.pixi.me/v/kiosk/ |
| 23:47.08 | brlcad | someone should take a look at what jra just implemented in jbrlcad to convert it to librt... |
| 23:47.34 | Yoshi47 | is brlcad using java libs? |
| 23:47.39 | brlcad | maybe a src/conv tool that uses it .. arb6tobot |
| 23:47.40 | Ralith | no. |
| 23:47.47 | brlcad | yeah, no. ;) |
| 23:47.48 | Ralith | there was an experimental thing |
| 23:47.52 | Ralith | but afaik it's dead now |
| 23:47.57 | brlcad | it's not dead |
| 23:47.57 | Yoshi47 | Ralith, good |
| 23:48.00 | Ralith | inactive? |
| 23:48.04 | ``Erik | well, there's jbrlcad which is a tiny subset of librt written in java, but it's seperate |
| 23:48.14 | ``Erik | daytona pokes at it on occasion |
| 23:48.14 | brlcad | it's actually in production use.. it's just "done enough" for that purpose for now |
| 23:48.21 | Yoshi47 | umm |
| 23:48.28 | brlcad | none of our tools uses it |
| 23:48.41 | Yoshi47 | why would they use java for just a tiny bit? |
| 23:48.51 | ``Erik | and there's src/librtserver/ which exposes some of the C librt to java via JNI, but it requires java interface classes that are not publically available |
| 23:49.08 | brlcad | librtserver is closer to being dead |
| 23:49.27 | ``Erik | and a notion that we'd like to expose a lot of our shtuff via swig, which'd allow a java target |
| 23:49.39 | ``Erik | are they giving up librtserver for the GS? |
| 23:49.39 | brlcad | jbrlcad lets them access a .g and shoot rays at geometry without needing to bridge across JNI |
| 23:50.14 | *** join/#brlcad docelic (n=docelic@78.134.202.224) |
| 23:50.49 | Yoshi47 | what does the whole collaborative thing do? network helping? viewing? |
| 23:51.08 | Ralith | which collaborative thing? |
| 23:51.29 | Ralith | the geometry server project is at least in part targeted at allowing people to work together on a single model, I believe. |
| 23:51.37 | Ralith | but I doubt that's what you're talking about |
| 23:51.54 | Yoshi47 | the menu item under modes |
| 23:52.02 | Ralith | oh, an mged thing. |
| 23:52.15 | Yoshi47 | ya |
| 23:52.37 | Yoshi47 | thats all i know right now, besides, g-dxf, dxf-g, pix-png |
| 23:53.00 | Ralith | huh. no idea. |
| 23:53.01 | Yoshi47 | ive only touch a bit |
| 23:53.23 | Yoshi47 | Ralith, didni't you do through the whole old interface before designing the new one? |
| 23:53.32 | Ralith | nope. |
| 23:53.54 | Ralith | I'm familiar with its basics, but I fall far short of knowing the function of every menu item :P |
| 23:54.08 | brlcad | when you turn on collaborate, another mged can attach and you share the same geometry view |
| 23:54.21 | Ralith | neat! |
| 23:54.26 | Yoshi47 | another mged from another pc or same X |
| 23:54.28 | mafm | congratz, gsoc folks |
| 23:55.26 | Yoshi47 | on behalf of gsoc folks, thank you! lol |
| 23:55.45 | mafm | I mean Ralith and the rest |
| 23:55.50 | Yoshi47 | im their spokes person |
| 23:55.51 | Yoshi47 | i know |
| 23:55.54 | ``Erik | heh |
| 23:55.55 | mafm | though I don't see the rest around much :P |
| 23:55.57 | Yoshi47 | no one was answrring |
| 23:56.04 | ``Erik | raises his beer to all the gsoc folk O.o |
| 23:56.14 | *** topic/#brlcad by brlcad -> BRL-CAD Open Source Solid Modeling || http://brlcad.org || http://sf.net/projects/brlcad || Release 7.14.8 posted (20090511) || GSoC2009 Next Step: upload your code to google, wait for shirt ;) thanks everyone! |
| 23:56.15 | Yoshi47 | i raised my MUG(root beer) |
| 23:56.17 | Ralith | does think that the rest are missing out by not IRCing harder. |
| 23:56.23 | Ralith | upload to google? |
| 23:56.37 | brlcad | you have to upload your code to google |
| 23:56.50 | Ralith | okie. |
| 23:56.52 | brlcad | it's technically what they pay you for, you're "testing" their upload service :) |
| 23:56.56 | Ralith | heh |
| 23:56.59 | Ralith | digs for menu item |
| 23:56.59 | Yoshi47 | lol |
| 23:57.01 | louipc | you have to upload all your patches? |
| 23:57.07 | brlcad | yeah, basically |
| 23:57.13 | Ralith | er, that sounds complicated. |
| 23:57.13 | louipc | CRAZY |
| 23:57.17 | Ralith | can I just send them a tarball of g3d? :P |
| 23:57.29 | ``Erik | some mentors can't irc from work and want to spent their home time with their family *shrug* I know it sounds insane, but some people honestly have better things to do than sit around on irc O:-) |
| 23:57.36 | Yoshi47 | zip then encrypt it too! |
| 23:57.36 | Ralith | (yeah, I know, I'll find their docs) |
| 23:57.38 | ``Erik | does not. :( |
| 23:57.42 | Ralith | ``Erik: I mean the students |
| 23:57.47 | louipc | Ralith: send them a diff from when you started ;) |
| 23:57.52 | louipc | hehehhhe |
| 23:57.56 | brlcad | I think they just want the code you wrote/worked on, but an svn diff from when you started to know might be sufficient too -- have to read the requirement |
| 23:58.01 | ``Erik | yeh, the students benefit quite a bit from jabbering on irc I think |
| 23:58.13 | Ralith | I know I have |
| 23:58.19 | Ralith | not to mention being easily accessible for brlcad to poke at >_> |
| 23:58.31 | brlcad | :) |
| 23:58.35 | brlcad | pokes Ralith |
