| 12:20.11 | elf_ | solved that problem with the way images were showing too dark to see anything in the simulation, it was a lighting problem, setting up an attribute for the default light of the scene did the trick |
| 12:20.32 | elf_ | here's the latest updated page of the simulation http://brlcad.org/wiki/Mged_simulation |
| 12:20.50 | elf_ | and here's the video http://youtu.be/XS1wUnQ8q0M |
| 12:58.40 | brlcad | elf_: that's showing up in psychadelic flashing pink and blue on my screen |
| 12:58.45 | brlcad | is that intended?? |
| 13:14.44 | elf_ | It is supposed to be all pink, the blue was there from somewhere, couldn't figure out from where though. The thing is that without the -A30 parameter the rt command keeps the image darkened, like this one http://youtu.be/KhE0HO8Uloc , if I add the lighting the geometry is properly lit but the colors are much more stronger |
| 13:15.53 | elf_ | and no matter what color I set up for that mater plastic command or any color I set with comb_color command when I rt it outside mged I get that "psychadelic pink" |

| 14:09.44 | brlcad | elf_: but what does an individual frame look like |
| 14:11.19 | elf_ | brlcad, this is what an individual frame looks like http://imageshack.us/a/img267/8663/image1fr.png |
| 14:11.47 | brlcad | yeah, that's way too bright |
| 14:12.10 | brlcad | so couple problems to fix |
| 14:12.13 | elf_ | I know, though you saw in the other youtube link, without the light it shouldn't be that bright |
| 14:12.27 | brlcad | first off, ignore youtube |
| 14:12.32 | elf_ | The lighting it's only on 30% so definitely not that bright |
| 14:12.34 | brlcad | that's just one more layer of compression |
| 14:12.40 | elf_ | okay |
| 14:12.45 | brlcad | the problem is in the conversion from image frames to movie |
| 14:13.00 | brlcad | the movie should look like the image frames |
| 14:13.08 | brlcad | if it doesn't, it's a movie encoding problem |
| 14:13.29 | elf_ | I used imageMagick |
| 14:13.52 | brlcad | using imagemagick is fine |
| 14:14.02 | elf_ | no compression, except the one that the convert command from ImageMagick does |
| 14:14.40 | brlcad | so lets step back, do you have a set of image frames that aren't A30? |
| 14:17.11 | elf_ | yes I do |
| 14:17.37 | brlcad | also, this image (http://brlcad.org/wiki/Image:Simulation_1.png) needs to be redone... suggest a full window screenshot, move the model down a little bit so everything is in view |
| 14:18.05 | brlcad | could make the window a little bigger and zoom 1.3 more or so |
| 14:18.19 | brlcad | er, make the window a little *smaller* |
| 14:18.27 | elf_ | okay |
| 14:21.12 | brlcad | 10:17 < elf_> yes I do <-- can you show me? :) |
| 14:21.35 | elf_ | yeah a sec, was going to upload a pic but imageshack is being dificult |
| 14:24.28 | elf_ | Here http://imageshack.us/a/img4/8472/image982.png |
| 14:25.00 | brlcad | er ,that's a black image |
| 14:25.37 | elf_ | no, that's the thing it's a dark image, but if you look under the right angle you'll see the plane and the cube above it |
| 14:25.57 | elf_ | it's some kind of dark pink or something |
| 14:26.23 | brlcad | if that's a render frame, then your scene isn't right |
| 14:27.02 | elf_ | It's what I get after running the simulate script so yeah a render frame |
| 14:27.08 | brlcad | I yes, I see it now |
| 14:27.10 | brlcad | that's not right |
| 14:28.28 | elf_ | I thought it was supposed to look something like the image after I run the raytracing tool in mged so that's why I asked yesterday if I can do something like that in the script |
| 14:28.32 | brlcad | that's what you get if you exactly follow your tutorial steps? |
| 14:28.41 | brlcad | or did you add a light to the scene or something? |
| 14:29.07 | brlcad | it should look the same as when you run it in mged |
| 14:29.22 | elf_ | That's what I get if I follow the tutorial steps, running the simulate script, both the one with the viewset and the one without it, without the -A option |
| 14:29.54 | elf_ | In mged I get both the cube and the plane in a gray color |
| 14:29.59 | elf_ | on the black background obv |
| 14:31.57 | brlcad | I'm going to try the steps now myself -- while I'm doing that, perhaps you can create a better mged screenshot or fix up the paragraph before the mater commands to explain what the other options are -- suggest just running "mater cube.r" and answering the interactive prompts so people can see what each is |
| 14:33.29 | elf_ | okay |
| 14:44.09 | brlcad | (like you did for the 'in' command) |
| 14:45.23 | brlcad | instructions say "sed box" but I think you meant sed cube? |
| 14:46.35 | brlcad | you say "We want our ground plane and cube to have a texture" but that's not true or what you later describe |
| 14:46.45 | brlcad | you want it to have color and material properties |
| 14:46.49 | brlcad | texture means something else |
| 14:46.51 | elf_ | yes I modified that now when I am adding the explanations for the mater |
| 14:46.58 | elf_ | sed box was old |
| 14:47.16 | elf_ | you are right about the texture |
| 14:48.16 | brlcad | after "You should get the following answer:" ... that is not what I get following your instructions |
| 14:48.31 | elf_ | you get cube gp and sim.c |
| 14:48.37 | brlcad | nope |
| 14:49.31 | brlcad | okay, so I think I see where some of the problems are coming from |
| 14:50.13 | brlcad | what's in sim.c for you? |
| 14:50.15 | brlcad | l sim.c |
| 14:51.07 | elf_ | the cube and the gp regions grouped |
| 14:51.27 | brlcad | that's not precise |
| 14:51.32 | brlcad | what does l sim.c say |
| 14:51.52 | elf_ | sim_gp.r sim_cube.r bb_reg_sim_gp.r bb_reg_sim_cube.r |
| 14:52.16 | brlcad | l sim_cube.r |
| 14:52.44 | brlcad | so that is most definitely not "the cube and the gp regions grouped" for starters |
| 14:53.06 | elf_ | meant to ask you how do you copy paste from the mged window? |
| 14:53.43 | brlcad | it's four objects, presumably regions, created by the simulate command .. what those four objects are depends on what is in them |
| 14:53.55 | brlcad | what platform are you on? |
| 14:53.59 | elf_ | linux |
| 14:54.11 | brlcad | it's the same copy-paste as any other X window |
| 14:54.22 | brlcad | usually select text, then middle mouse |
| 14:55.18 | elf_ | it's not working, tried ctrl+c / ctrl+shift+c then to paste it in here |
| 14:55.47 | brlcad | do you have a three-button mouse? |
| 14:56.08 | elf_ | sim_cube.r: REGION id=1000 (air=0, los=100, GIFTmater=1) --Shader 'plastic {tr 0.2 re 0.2} 'Color 50 0 0 u cube [0, 0, -0.291666] scale 1 |
| 14:56.15 | elf_ | that worked the mouse |
| 14:57.19 | brlcad | so there it looks like the simulate command is creating it's own copy of the two regions you were displaying (cube.r and gp.r), making sim_cube.r and sim_gp.r |
| 14:57.25 | brlcad | don't know what the other two objects are for |
| 14:58.00 | brlcad | next thing to add to the tutorial is to show them the scene you had them create |
| 14:58.15 | elf_ | Yeah. that I knew, it is supposed to work like that, in the simulate.c file I think, it needs those 2, that's why the ground region needs to be named gp.r |
| 14:58.31 | brlcad | you tell them all these in/mater/r commands, then jump straight to simulate without showing them what you made |
| 14:59.08 | brlcad | elf_: you may know it, but you're not *saying* it .. and it's certainly not being made clear in the tutorial... :) |
| 14:59.20 | elf_ | You are right |
| 14:59.55 | brlcad | before the "Now we are ready to run the simulate command" line .. I suggest adding two more commands |
| 15:00.01 | brlcad | ae 35 25 |
| 15:00.03 | brlcad | autoview |
| 15:00.18 | brlcad | then embed a screenshot there of what that looks like |
| 15:00.34 | elf_ | okay |
| 15:00.58 | brlcad | that way they'll know if they got anything wrong, they can see the scene, and it's more clear what happens when the simulate command runs |
| 15:01.12 | elf_ | the other 2(bb_reg_sim_cube.r and bb_reg_sim_gp.r) are the bounding box for the simulation |
| 15:01.25 | elf_ | right I will add those |
| 15:02.15 | brlcad | the problem is that sim.c puts them all together -- that means you'll have overlapping regions, which is wrong to render |
| 15:02.58 | elf_ | I do have overlapping regions, lots of those actually. So uhmm how can I get those out of the sim.c? |
| 15:03.00 | brlcad | technically wrong to model but the simulate command is a work in progress |
| 15:03.55 | brlcad | g bb.c bb_*.r |
| 15:04.14 | brlcad | rm rm sim.c bb_*.r |
| 15:04.31 | brlcad | oops, just: rm sim.c bb_*.r |
| 15:04.51 | elf_ | hmm will try it |
| 15:05.15 | brlcad | elf_: after autoview, add an "rt" command -- that's a better window to screenshot |
| 15:05.31 | brlcad | or "rt -W" |
| 15:06.05 | elf_ | ok |
| 15:07.16 | brlcad | also suggest changing tra 0 0 100 to tra 0 0 50 (no use starting so high, just makes it hard to see the box |
| 15:08.14 | elf_ | yes, it can get even lower for a better view, with the ground plane a little smaller, it will look better |
| 15:11.19 | brlcad | try this view: |
| 15:12.13 | brlcad | ae 35 15 |
| 15:12.21 | brlcad | tra 0 10 0 |
| 15:12.38 | brlcad | rather: ae 35 15 ; autoview ; tra 0 10 0 |
| 15:12.47 | brlcad | then rt or rt -W |
| 15:13.01 | brlcad | the ground plane size is good |
| 15:15.52 | brlcad | i like the size ratio you came up with, I think that works well |
| 15:16.17 | brlcad | just started really far apart and 35 25 is an odd angle for watching it drop |
| 15:16.20 | elf_ | It looks good |
| 15:16.35 | elf_ | with your settings I mean :) |
| 15:17.59 | brlcad | so suggest making all those updates and redo just the first video and we'll see what it looks like |
| 15:18.48 | elf_ | okay working on it and on the wiki page |
| 15:19.03 | brlcad | note the video script command needs to change, rt -a 35 -e 10 .. and not sim.c but "sim_cube.r sim_gp.r" |
| 15:19.21 | brlcad | (and should explain why those two earlier) |
| 15:19.26 | brlcad | you don't want the bb's |
| 15:20.06 | brlcad | before Z, can explain what sim.c is, show the l listing with four objects |
| 15:20.08 | elf_ | right, then I should let them see that the sim.c group is not just the sim_cube.r and sim_gp.r but also the 2 bb, and we don't want those there |
| 15:20.40 | brlcad | don't need to go through those steps I gave you to remove the bb, can just use those two regions instead of sim.c |
| 15:20.51 | brlcad | but should explain that and why |
| 15:21.01 | elf_ | got it |
| 15:21.25 | brlcad | so thats a lot of things .. you going to remember all of that? :) |
| 15:21.51 | elf_ | That's what I have all this convo for :) |
| 15:27.52 | brlcad | 1) full window mged screenshot at intro, 2) sed box/cube, 2a) 0 0 50, 2b) still have "matter" in there, 3) set up view, run rt before simulate, 4) add rt window screenshot, 5) explain sim.c, 6) draw sim_cube.r sim_gp.r, 7) add screenshot after "draw cube.r" after simulate to see difference, 8) update simulation script -- no A30, no sim.c, 400 steps. also suggest letting it be default size (512x512) so you don't have to explain that there, let the second one be |
| 15:28.56 | brlcad | can double-check me with the convo, but that's most of what I recall plus a couple other details |
| 15:29.45 | elf_ | Thank you for summarizing it :) |
| 15:30.02 | brlcad | after you rebuild the first simple animation, we'll see what that looks like with the other updates |
| 15:30.28 | *** join/#brlcad paulproteuss (~paulprote@rose.makesad.us) |
| 15:30.33 | paulproteuss | brlcad: Hey, are you Sean? (: |
| 15:31.00 | brlcad | paulproteuss: hi and it depends who is asking ;) |
| 15:31.12 | brlcad | or more specifically, why you'd be asking that :) |
| 15:31.32 | paulproteuss | I'm Asheesh, and I'm curious if there are any bitesize brlcad bugs that might interest Hopkins students this weekend (see also https://openhatch.org/wiki/Open_Source_Comes_to_Campus/JHU ) |
| 15:31.52 | brlcad | ah, hey asheesh |
| 15:31.54 | paulproteuss | Doc fixes, or compile warning fixes, or tiny tiny feature additions, etc. |
| 15:31.56 | brlcad | I heard about that |
| 15:31.58 | paulproteuss | (-: |
| 15:32.07 | paulproteuss | I thought you might have, but I also thought I'd try pinging you directly to see what happens. |
| 15:32.08 | brlcad | congrats on the setup |
| 15:32.21 | paulproteuss | Thanks! |
| 15:32.22 | brlcad | you still in sanfran? |
| 15:32.45 | paulproteuss | Generally, though at the moment I'm in Baltimore, prepping! |
| 15:33.00 | brlcad | nods, very good |
| 15:33.13 | brlcad | so what level of effort are you thinking .. how tiny? |
| 15:33.29 | brlcad | like 10 minute tiny, or 60 min tiny, or 1 day tiny? |
| 15:33.33 | paulproteuss | 10-60 min |
| 15:33.50 | paulproteuss | Up to 90 I suppose, but given variance of experience between students, those numbers vary. |
| 15:34.25 | paulproteuss | There could be some epic C hackers who can fix one-day bugs in one hour, but mostly I expect freshman and sophomores. |
| 15:34.26 | brlcad | we have http://brlcad.org/wiki/Quickies but they're anywhere from 10 minutes to 20 hours (mostly depending on user experience) |
| 15:34.59 | brlcad | I have an openhatch account, but I think I'd created it before tasks could be added |
| 15:35.06 | brlcad | or there was some problem, don't recall, that was more than a year ago iirc |
| 15:35.11 | paulproteuss | Wow, this is one great page. |
| 15:35.56 | paulproteuss | libbn docs fixes seems pretty great to me. |
| 15:36.07 | brlcad | yep |
| 15:36.23 | brlcad | there are a couple dozen files |
| 15:36.37 | brlcad | so moving the comments for just one file would be a perfect patch that'd probably take less than 10 minutes |
| 15:37.04 | brlcad | quick recompile to make sure a typo wasn't fat fingered in |
| 15:37.37 | paulproteuss | And it's svn, so openhatch.org/missions/svn seems relevant |
| 15:38.13 | brlcad | hah, nifty -- hadn't seen missions |
| 15:38.49 | paulproteuss | Every once in a while I wonder if we should move that to its own site. |
| 15:39.12 | paulproteuss | But for now, I'm focusing on the events, and will consider web tech ramifications another time! |
| 15:39.26 | brlcad | ahhhh.. that's right -- now I'm remembering |
| 15:40.18 | brlcad | you have that cool bug tracking interface, but not one for sourceforge and not one for a "raw"/xml/whatever dump format to be added manually... :) |
| 15:41.20 | brlcad | looked into migrating some of our tasks into trac, but that effort was stalled |
| 15:41.44 | paulproteuss | Behind the scenes there's an epic rewrite of the bug import code, which will make it a bajillion times less stressful to add support for other tracker types. |
| 15:42.27 | paulproteuss | The epic rewrite makes there be less code, which is what good rewrites are for! |
| 15:42.33 | paulproteuss | But anyway. (-: |
| 15:42.48 | brlcad | :) |
| 15:49.32 | brlcad | paulproteuss: so I'm reminded that the event is tomorrow, do you need anything else other than that wiki page? I can probably flesh out a few more VERY EASY coding entries before tomorrow |
| 15:51.33 | paulproteuss | One thing I want to do is test how long it takes to compile brlcad before I accept too many new suggestions from you. |
| 15:51.41 | paulproteuss | Let me go kick that off! |
| 15:51.51 | brlcad | dev guide goes into detail on participation including patches: http://brlcad.svn.sourceforge.net/viewvc/brlcad/brlcad/trunk/HACKING |
| 15:52.41 | paulproteuss | Nice! |
| 15:52.44 | brlcad | best is the new cmake build system, compiles in parallel much better than autotools |
| 15:52.55 | paulproteuss | If you update that wiki page, just ping me so I can be sure to know about the task. |
| 15:53.09 | paulproteuss | I'm keeping a private spreadsheet for my own notes about what tasks I've personally looked at that seem excellent. |
| 15:53.55 | brlcad | my 5-year old 2-core laptop compiles the whole package in about 15 minutes, latest macbookpro compile was about 3 minutes iirc |
| 15:54.19 | paulproteuss | Well that's just totally excellently fast. |
| 15:54.31 | paulproteuss | By contrast, LibreOffice takes about 3.5h, and Firefox 3h, on my laptop. |
| 15:54.37 | paulproteuss | I guess C++ actually is slow to compile. Who knew? |
| 15:54.50 | brlcad | yeah, our C++ sources doubled our compile time |
| 15:55.04 | brlcad | about 25% of our sources are c++ and they account for at least 50% of the compile time |
| 15:55.21 | brlcad | well that and docbook/xml processing ... |
| 15:56.37 | paulproteuss | Oh, computers. |
| 15:57.14 | brlcad | paulproteuss: don't know if it's any use, but we pulled together a VM with BRL-CAD pre-downloaded into a linux distro with all dependencies installed, it's available https://sourceforge.net/projects/brlcad/files/BRL-CAD%20for%20Virtual%20Machines/ |
| 15:57.48 | brlcad | freebsd and haiku have similar setups handy to help new contributors jump in |
| 15:59.06 | brlcad | don't think it'll save you time for tomorrow, but maybe something to mention that some projects might offer |
| 16:02.01 | paulproteuss | Amusing that svn checkout will probably take way longer than the build. |
| 16:45.55 | brlcad | just updated http://brlcad.org/wiki/Compiling |
| 16:46.14 | brlcad | hm, looks like CIA is AWOL |
| 16:55.34 | brlcad | paulproteuss: just saw your acm note in my digest, replied with a brief summary |
| 16:55.43 | brlcad | mainly for others, of course |
| 17:04.32 | elf_ | brlcad, here's how the gif looks like right now http://imageshack.us/a/img515/2659/simc.gif |
| 17:05.01 | elf_ | I don't like the fact that the image seems to be moving by all when the cube comes closer to the ground plane |
| 17:05.17 | elf_ | I think it has something to do with the way the view is set... |
| 17:05.25 | elf_ | or it might be something else? |
| 17:05.44 | brlcad | elf_: that's something to talk about in the tutorial |
| 17:05.55 | brlcad | and is motivation for the second script |
| 17:06.02 | brlcad | but don't worry about it right now |
| 17:06.17 | elf_ | okay |
| 17:06.50 | elf_ | uhmm the file is also kinda large... 1.5mb I think the limit to the site is 1mb |
| 17:08.26 | brlcad | still want to make sure the color is right .. don't worry about adding animations yet |
| 17:09.08 | brlcad | so for the two rt images you embedded, can you make them be the full render |
| 17:09.35 | brlcad | either the full rt window or at least the full 512x512 image |
| 17:09.58 | brlcad | can run "rt -W -o file.png" to stash the rendering |
| 17:10.27 | elf_ | Ahh I updated the wiki file if that's what you are asking http://brlcad.org/wiki/Mged_simulation |
| 17:10.50 | brlcad | also missing the tra after autoview to get it centered better for the mged screenshots |
| 17:11.01 | brlcad | I'm referring to the wiki page |
| 17:12.01 | brlcad | and iterations still seem too short |
| 17:12.09 | elf_ | okay, I will add the tra and I am sorry but I don't understand what do you mean by making them full render? |
| 17:12.18 | brlcad | want to see the box hit the surface, the animation ends too early |
| 17:12.45 | brlcad | check the 1,2,3,4,5,... list again .. there are a couple more things in there that I don't see too |
| 17:13.03 | elf_ | Iterations are 185 for the cube to be on the plane, that's what I ran the first script with |
| 17:13.07 | elf_ | and it landed on the ground |
| 17:13.18 | elf_ | more of it and it gets inside the plane |
| 17:13.47 | brlcad | so the collision detection failed :) |
| 17:14.10 | elf_ | yep |
| 17:14.18 | elf_ | not entirely though |
| 17:14.40 | brlcad | that was working, so maybe a question for abhijit or the first code you can work on, but for the animation, just let it go through |
| 17:14.59 | brlcad | stopping the video just looks odd |
| 17:15.03 | elf_ | it got in the ground plane, it looked like half of the cube was in the ground plane then it turned on it's side then the simulate stopped |
| 17:15.17 | elf_ | there are another 5 images after the gif that I showed you |
| 17:15.38 | elf_ | okay, will add the 5 more images till the cube stops moving |
| 17:16.39 | brlcad | what I meant about "full render" is that http://brlcad.org/wiki/Image:Geometry_of_simulation.png and http://brlcad.org/wiki/Image:Simulation_rt_100.png appear to be screen captures, not the actual rendered image |
| 17:16.53 | brlcad | subtle difference only because your screen capture is off by a pixel |
| 17:17.49 | brlcad | it should either be the actual render image (rt -W -o file.png) or the actual full window with the title bar and all, captured with a window-capture tool |
| 17:18.02 | brlcad | not just eyeballing it with your mouse |
| 17:18.16 | elf_ | okay, got it, didn't know I could do the rt -W -o trick |
| 17:20.27 | brlcad | doesn't need to be in the instructions, more for you to get the image |
| 17:21.12 | brlcad | and you did know, note your animation script uses that option ;) |
| 17:21.51 | elf_ | right again :)) |

| 18:22.10 | brlcad | elf_: http://brlcad.org/wiki/Image:Geometry_of_simulation.png is what you actually get after autoview + tra 0 10 0 ? |
| 18:24.27 | elf_ | Hmm, I am not sure, I might have put some zoom in it, it doesn't look like the other ones |
| 18:39.24 | elf_ | brlcad, here's the page and I added the simulation with the viewset gif in 256x256 format, I have to add a smaller version of this one http://imageshack.us/a/img829/5530/simtotal.gif (the one without the viewset) |
| 18:39.46 | elf_ | but I started rendering the one with the viewset in 800x800pixels and it takes some time |
| 18:40.00 | elf_ | uhmm like a lot of time |
| 19:02.15 | brlcad | don't do the big one yet! |
| 19:03.31 | brlcad | elf_: it still doesn't look right |
| 19:03.36 | elf_ | kay will stop it it didn't get too far anyway |
| 19:04.02 | brlcad | so with the first one, what does one of the actual movie frames look like? |
| 19:04.45 | elf_ | http://imageshack.us/a/img11/8977/image1erc.png |
| 19:05.33 | brlcad | hat doesn't look right |
| 19:06.09 | elf_ | what's amiss? |
| 19:06.14 | brlcad | you may be dealing with a bug, but try running this: rt -a 35 -e 15 -o test.png sim.g sim_gp.r sim_cube.r |
| 19:06.41 | brlcad | and: rt -a 35 -e 15 -o test2.png sim.g gp.r cube.r |
| 19:06.43 | elf_ | no that's the one with the viewset |
| 19:06.58 | brlcad | what? |
| 19:07.16 | brlcad | run those two commands outside of mged |
| 19:07.47 | elf_ | the one that I showed you it's the image with the view set, from the small gif from the wiki page |
| 19:08.13 | elf_ | http://imageshack.us/a/img805/5145/image1iz.png this is the one from the link with the bigger anymation I posted |
| 19:08.29 | brlcad | okay, but still doesn't look right |
| 19:08.44 | elf_ | will run the commands in a terminal |
| 19:09.01 | brlcad | that is WAY darker than it should be, looks like zero ambient |
| 19:11.12 | elf_ | test 1 http://imageshack.us/a/img145/3820/testkp.png |
| 19:11.14 | brlcad | if that's a bug, it needs to be isolated and fixed |
| 19:11.24 | elf_ | test 2 http://imageshack.us/a/img43/6624/test2zb.png |
| 19:11.47 | brlcad | okay, so it's not the simulation causing a problem |
| 19:12.08 | brlcad | try: rt -a 35 -e 15 -o test3.pix sim.g gp.r cube.r |
| 19:12.35 | brlcad | followed by: pix-png -o test3.png test3.pix |
| 19:14.11 | elf_ | http://imageshack.us/a/img443/9375/test3j.png |
| 19:14.59 | brlcad | okay, and if you run this: rt -a 35 -e 15 sim.g gp.r cube.r |
| 19:15.06 | brlcad | does it show up dark in the window |
| 19:16.08 | elf_ | if I run that in mged or out of it? |
| 19:16.14 | brlcad | out |

| 19:17.35 | elf_ | damn long thing... short story it doesn't open anything |
| 19:17.57 | brlcad | huh, that's odd |
| 19:18.24 | brlcad | specify the framebuffer: rt -F/dev/oglp -a 35 -e 15 sim.g gp.r cube.r |
| 19:19.16 | elf_ | I get a transparent window with the plane and cube |
| 19:19.30 | brlcad | starseeker: couple lines that would be great to add to your .vimrc ... |
| 19:19.30 | brlcad | :highlight ExtraWhitespace ctermbg=red guibg=red |
| 19:19.31 | brlcad | :match ExtraWhitespace /\s\+$/ |
| 19:19.57 | brlcad | so you can see where you drop those turds that carl chases after |
| 19:20.24 | brlcad | elf_: i don't understand what that means |
| 19:20.41 | brlcad | the question is whether it shows up dark like the other images were |
| 19:21.29 | elf_ | it doesn't show up dark like other images cause the whole window is transparent, like glass and you paint on it the cube and the ground plane |
| 19:21.40 | brlcad | if a window is transparent, you're saying you can see through it |
| 19:21.49 | brlcad | screenshot? |
| 19:23.45 | brlcad | then try: rt -W -a 35 -e 15 -o test4.png sim.g gp.r cube.r |
| 19:24.02 | elf_ | http://imageshack.us/a/img339/3395/transparentap.png |
| 19:24.45 | brlcad | wtf |
| 19:25.04 | elf_ | told you it was transparent... |
| 19:25.09 | brlcad | is that your desktop background? |
| 19:25.37 | brlcad | expecting to see the window decoration |
| 19:27.04 | elf_ | http://imageshack.us/a/img542/2149/test4b.png |
| 19:27.13 | elf_ | yes that's the desktop background |
| 19:27.46 | elf_ | I use the screenshot in ubuntu and it is setted not to show the window decoration |
| 19:27.55 | elf_ | I can take another one with the decoration |
| 19:27.59 | brlcad | ah |
| 19:28.27 | brlcad | so the short term fix is to add -W to your first script |
| 19:28.48 | brlcad | -W -s256 |
| 19:28.50 | elf_ | I hope this has nothing to do with the fact that I didn't install mged, I am running it from the folder where I build it, so I use bin/rt bin/mged etc for commands |
| 19:29.00 | brlcad | that shouldn't matter |
| 19:29.04 | elf_ | okay |
| 19:29.07 | elf_ | wanted to make sure |
| 19:29.33 | brlcad | is this also "transparent": rt -F/dev/X -a 35 -e 15 sim.g gp.r cube.r |
| 19:31.29 | brlcad | it's suspicious that it says /usr/brlcad/dev-7.22.0 for the install path |
| 19:31.40 | brlcad | should be /usr/brlcad/dev-7.22.1 if building from an svn checkout |
| 19:33.18 | elf_ | the latest command Compile-time debug symbols are available |
| 19:33.19 | elf_ | Running on elfy |
| 19:33.19 | elf_ | Planning to run with 4 processors |
| 19:33.19 | elf_ | bin/rt -F/dev/X -a 35 -e 15 |
| 19:33.19 | elf_ | opendb sim.g; |
| 19:33.19 | elf_ | tree gp.r cube.r; |
| 19:33.21 | elf_ | rt: rt_dirbuild(sim.g) failure |
| 19:34.07 | elf_ | I didn't build from the latest svn checkout... it was from the latest official release |
| 19:35.20 | brlcad | ok |
| 19:35.27 | brlcad | so the dirbuild failure is something you're doing |
| 19:35.36 | brlcad | all the other examples I gave were sim.g |
| 19:35.46 | brlcad | so you either removed the .g file or you replaced with another |
| 19:36.02 | brlcad | it looks like you used s3.g |
| 19:37.41 | elf_ | the s3.g file I am using is the same as the sim.g file you are using |
| 19:38.40 | elf_ | but you are right now I ran it with the wrong file |
| 19:38.55 | elf_ | and with that command I get a dark window |
| 19:40.00 | brlcad | okay, so redo the anim with -W -s256 and should make a more interesting script for the higher quality one |
| 19:42.08 | elf_ | A more interesting script? |
| 19:42.14 | elf_ | What do you have in mind? |
| 19:42.21 | brlcad | a multipass render |
| 19:42.50 | brlcad | so right now you have it rendering a 800x800 directly to a pix file, then converting the pix to a png |
| 19:43.29 | brlcad | suggest starting an fbserv, rendering into it twice, then extracting your png |
| 19:43.35 | brlcad | what's your screen resolution? |
| 19:45.09 | elf_ | 1366x768 pixels |
| 19:45.20 | brlcad | ouch |
| 19:45.21 | brlcad | okay |
| 19:45.28 | brlcad | you can add this to the beginning of your high-res script: |
| 19:45.48 | elf_ | I am on a laptop.. that's why |
| 19:46.01 | brlcad | fbserv -W 360 -N 640 5 /dev/X & |
| 19:46.21 | brlcad | then change the line that says: rt -M -s800 -o image$i.pix \ |
| 19:47.35 | brlcad | to say: rt -M -w 360 -n 640 -W -F5 \ |
| 19:48.23 | brlcad | then duplicate that whole block to the EOF |
| 19:48.37 | brlcad | and change the second rt -M -w 360 -n 640 -W -F5 \ to say ... |
| 19:49.19 | brlcad | rtedge -M -w 360 -n 640 -W -F5 -c "set ov=1" \ |
| 19:49.49 | brlcad | finally, instead of pix-png -s800 image$i.pix > image$i.png ... |
| 19:50.11 | brlcad | run fb-png -F5 -w 360 -n 640 image$i.png |
| 19:51.01 | brlcad | add a "kill %1" command after the for loop to shut down the fbserv |
| 19:52.11 | elf_ | like this http://brlcad.org/wiki/Mged_simulation ? |
| 19:53.10 | brlcad | yep! |
| 19:53.46 | brlcad | check your script, though |
| 19:53.50 | brlcad | don't need rm -f image$i.pix for example |
| 19:54.43 | brlcad | any reason you don't simulate to 200? |
| 19:54.55 | brlcad | nice round number |
| 19:55.14 | brlcad | even if it stops moving at 190, that's be useful |
| 19:56.25 | elf_ | I actually let it run till 200, but it doesn't go further than 190 it just stops there and stays like that for a long time |
| 19:56.52 | brlcad | that's fine .. the extra animation frames will make the video better |
| 19:57.20 | brlcad | so that should keep your laptop hot for a while :) |
| 19:57.44 | elf_ | it will :)) |
| 19:57.52 | brlcad | while it's rendering, you can update the text to explain everything that changed and what does what |
| 19:58.33 | brlcad | I'd try to reduce the paragraph that start "In order to create an animation...." |
| 19:59.16 | brlcad | it can be a little more brief, like not needing to explain 512x512 being the default there |
| 20:00.09 | brlcad | azymuth is a typo :) |
| 20:00.48 | elf_ | you are right :) |
| 20:01.08 | brlcad | the imagemagick explanation should be right after the brief script too |
| 20:02.12 | brlcad | along with that video |
| 20:02.41 | brlcad | THEN proceed with, "well, that's great, but lets stop the view from constantly changing and make it look better..." |
| 20:04.51 | elf_ | okay will move it upper |
| 20:06.30 | brlcad | then you don't have to explain imagemagick and creating the video for the "big finale" |
| 20:08.30 | elf_ | You are right, it makes more sense to show them the movie and the gif creation after the first script, it's more logical, like a gradual learning process |
