| 00:59.45 | brlcad | summer of code summit was awesome, hopefully I can get this project to participate next year |

| 04:17.51 | louipc | damn I remember getting a month off |
| 07:09.44 | brlcad | I got a month off every year, even more if you counted the last days in december (though I wouldn't) -- same for friends in a half dozen other schools |
| 07:10.06 | brlcad | technically it was winter session, sometimes even could take a short course and get some credits out of the way |
| 07:11.46 | brlcad | either way, it's not meant to be perfect, it would have been simply to identify with a market that didn't overlap with google's program and *could* work, which it pretty much could regardless of whether you really like it .. |
| 07:12.22 | brlcad | summer isn't ideal either for tons of reasons |
| 07:12.37 | brlcad | i'd actually think we should do both, run a month long and run a 3 month program |

| 20:39.46 | starseeker | How goes it? |
| 20:40.01 | starseeker | Sorry about not being around - life has gotten... exciting of late |
| 20:41.24 | yukonbob | Hrmm... |
| 20:41.48 | yukonbob | not too bad here -- winter's set in by the look of it -- nothing too exciting going on... |
| 20:50.25 | starseeker | Heh - between work and my car it's been rather wild. |
| 20:52.54 | yukonbob | what's your work that it's "wild"? |
| 20:54.26 | brlcad | angasule: howdy |
| 20:54.30 | brlcad | Z80-Boy: yes |
| 20:55.42 | yukonbob | hey brlcad |
| 20:57.50 | starseeker | yukonbob: They like assigning projects that are outside my training, and don't let me finish ones that ARE inside my training |
| 20:57.50 | starseeker | brlcad: Glad to hear the summer of code meeting went well :-) |
| 20:57.50 | yukonbob | starseeker: ...is it interesting, or frustrating? |
| 20:57.52 | starseeker | yukonbob: With enough time and resources, it would be interesting. As it is... |
| 20:58.28 | ``Erik | heh, so you have a real job... ok? :LD |
| 20:58.29 | ``Erik | :D |
| 20:58.52 | brlcad | howdy yukonbob |
| 20:59.06 | brlcad | starseeker: it went great! |
| 20:59.10 | starseeker | ``Erik: Heh -pretty much |
| 20:59.17 | starseeker | brlcad: Excellent :-) |
| 20:59.18 | brlcad | already looking forward to doing it again next year |
| 20:59.30 | starseeker | What are your "A list" projects? |
| 20:59.42 | brlcad | for all of the hard work it took mentoring all of the students, the summit was one of the highlight return on investments |
| 20:59.51 | brlcad | BRL-CAD? |
| 20:59.53 | brlcad | BZFlag? :) |
| 20:59.57 | starseeker | Ah :-) |
| 21:00.11 | starseeker | I was thinking BRL-CAD, but bzflag is important too ;-) |
| 21:00.26 | ``Erik | probably more important |
| 21:00.33 | brlcad | there were lots of really good projects at the summit, just about every major OSS project was represented in some fashion |
| 21:00.59 | starseeker | "Deadline THIS Bob!" |
| 21:01.21 | starseeker | brlcad: Wow. What a neat opportunity to talk to the key players :-) |
| 21:02.03 | brlcad | text? |
| 21:02.14 | starseeker | You mean labels on models? |
| 21:02.28 | ``Erik | telnet bzflag.bz 32010 |
| 21:02.31 | brlcad | like annotations or wireframe text labels in the 3d scene? |
| 21:02.31 | ``Erik | > turn left |
| 21:02.32 | ``Erik | > fire |
| 21:02.56 | yukonbob | for labels in renderings, etc. Like povray -- so I could 'in mytitle text font size style "this is my text"', or similar... |
| 21:02.57 | brlcad | aww, connection refused :) |
| 21:03.09 | ``Erik | MSG from brlcad: get off my fucking server, twit! |
| 21:03.12 | ``Erik | *disconnected* |
| 21:03.14 | ``Erik | $ |
| 21:03.28 | brlcad | yukonbob: there already is a title -- the "title" command :) |
| 21:03.39 | brlcad | just doesn't display in the renderings (currently) |
| 21:03.57 | brlcad | talked about adding a "2D" overlay/annotation primitive |
| 21:04.04 | brlcad | that's on the ideas list to implement |
| 21:04.09 | yukonbob | brlcad: hrmm... /me will look into that -- I mentioned this before, but got no mention of 'title' (and didn't stumble/recognize it in browsing manuals) |
| 21:04.22 | brlcad | wouldn't even really be that hard -- the only trick is figuring out how it would interact with the ray-tracer if at all |
| 21:04.36 | brlcad | title is just that, a title that is set on geometry |
| 21:05.00 | brlcad | it's displayed in various places (like in the log during ray-tracing or as the window title in the geometry browser) |
| 21:05.05 | yukonbob | ..oh -- _that_ title -- ya -- I know that -- what about arbitrary text pasted as a renderable object, though... |
| 21:05.17 | brlcad | yeah, that'd be the new feature to add |
| 21:05.35 | brlcad | would be an excellent summer of code project idea :) |
| 21:05.44 | louipc | hmm how would that work? |
| 21:06.02 | brlcad | shouldn't take more than a month or so if they were familiar with coding |
| 21:06.14 | yukonbob | louipc: /me imagines it rendering TT fonts... a la povray |
| 21:06.30 | brlcad | yeah, that's slightly more tricky, but not impossible |
| 21:07.02 | starseeker | Would that be converting ttf structure to brlcad geometry? |
| 21:07.02 | louipc | would it make a texture on an invisible plane? |
| 21:07.21 | brlcad | I got true type font rendering in bzflag now via ftgl and freetype2, you could do something similar where you composite a rendered image with the font |
| 21:07.52 | brlcad | depends, whether you want it to be annotative or actually part of the scene, as a means to help model 3D text in the scene |
| 21:08.15 | brlcad | I wasn't thinking of making it 3D geometry just yet, annotations are a little more important |
| 21:08.16 | louipc | the text should be modifyable |
| 21:08.54 | poolio | alloo |
| 21:09.07 | louipc | salut |
| 21:09.10 | poolio | ca va? |
| 21:09.13 | yukonbob | ya -- annotations would be nice -- it's already done w/ the wireframes (axes, for example)... which would be nice to get semantics for display w/ rt setup... |
| 21:09.31 | starseeker | Sounds like in image editors - one layer for annotations which is otherwise transparent layered over the "image" |
| 21:09.35 | brlcad | another excellent form of implicit modelling -- the text correllates with some 3D shape implicitly depending on a specified font, position, and orientation |
| 21:09.51 | yukonbob | re: modifiable -- could be setup as attributes to objects... totally modifiable in that case... |
| 21:10.35 | yukonbob | actually, in that case, perhaps one could build a completely seperate tool that could query the DB, develop the text part, and make a composite image? |
| 21:11.17 | brlcad | yeah |
| 21:11.19 | louipc | poolio: ca va |
| 21:11.24 | brlcad | i think there's several viable ways |
| 21:11.26 | brlcad | with their tradeoffs |
| 21:12.06 | yukonbob | rt -o foo.pix model.g object; rtanno -i foo.pix -o newfoo.pix model.g object; |
| 21:13.35 | brlcad | yeah, had almost the exact same idea, cept it's labelled as rtannotate at the moment ;) |
| 21:13.47 | yukonbob | ;0 |
| 21:13.50 | yukonbob | ;), rather |
| 21:14.28 | starseeker | The beauty of tab completion on the command line :-) - no more is obscurity needed |
| 21:15.01 | yukonbob | starseeker: not everybody uses bash :( |
| 21:15.31 | louipc | yukonbob: what do you use? |
| 21:15.36 | yukonbob | sh |
| 21:15.39 | louipc | whoa |
| 21:15.40 | yukonbob | <PROTECTED> |
| 21:15.45 | louipc | hah! |
| 21:15.52 | starseeker | yukonbob: Well, if they seek out pain... |
| 21:15.57 | louipc | I don't even have sh |
| 21:16.13 | yukonbob | louipc: are you running a l00nucks? |
| 21:17.21 | starseeker | Guaranteed to defeat hackers as their brains explode trying to figure it out... |
| 21:17.22 | louipc | yukonbob: sh is a symlink to bash. No I'm running linux |
| 21:17.39 | ``Erik | heh, using 'creat' instead of 'create' is considered a mistake by the dude who wrote it (I forgot if that was thompson, ritchie, or who...) |
| 21:19.28 | yukonbob | ``Erik: yeh -- I remember reading an interview w/ Ritchie I believe, who considered not adding the 'e' the mistake he made with Unix... |
| 21:21.49 | yukonbob | sh is required by posix, whether it's traditional sh, or the gnu bastardized version... |
| 21:21.49 | ``Erik | bt I hv n prblm wth nt sng vwls n th nx trdtn |
| 21:21.49 | ``Erik | O:-) |

| 21:23.00 | brlcad | it' doesn't any more does it? |
| 21:23.14 | brlcad | i'd not had any problems since the fix |
| 21:23.15 | ``Erik | no, john fixed that |
| 21:23.25 | yukonbob | speaking of segfaults -- brlcad did you see that I revisited my earlier dsp issue (out of mem) and found it to be the same? |
| 21:23.32 | ``Erik | it'd be nice if it understood something about the input it's trying to complete |
| 21:23.37 | ``Erik | so opendb would complete on the filesystem |
| 21:23.40 | ``Erik | etc |
| 21:24.05 | ``Erik | and I have a suspicion that performance will suffer tab completing on large geometries, I think it's O(n) on names right now |
| 21:24.14 | brlcad | yukonbob: in all honesty, it's not gotten an honest slice of my attention in the debugger just yet other than to verify that confirming that it did look like a bug |
| 21:24.16 | ``Erik | using lsearch in tcl I think |
| 21:24.41 | brlcad | easy enough to test.. |
| 21:24.54 | Z80-Boy | brlcad: tab-completion? Woohoo! |
| 21:25.26 | ``Erik | 8 wheels and a keg party in the back? |
| 21:25.45 | louipc | hm? |
| 21:25.54 | ``Erik | the 'real model' :) |
| 21:27.24 | ``Erik | I did a tab completion thing in some code once upon a time, ended up using a trie because I had an obscenely slow machine :) |
| 21:27.45 | Z80-Boy | one could also use burrows-wheeler transform for tab completion |
| 21:27.47 | ``Erik | <-- points out that brlcad's desktop is *WAY* faster than dwaynes desktop *cough* |
| 21:27.56 | Z80-Boy | it would actually learn the things the user uses the most |
| 21:28.02 | brlcad | hm, seems to work fine with several hundred matches |
| 21:28.07 | brlcad | not even a blip on the cpu |
| 21:28.16 | ``Erik | how many million parts? |
| 21:28.58 | brlcad | dunno, just tried a few interactive |
| 21:29.23 | Z80-Boy | brlcad: if I have an unpushed matrix in a combination whose one part is an arbn then which functions are used? |
| 21:29.34 | ``Erik | *shrug* until someone complains, it's not an issue :) |
| 21:29.40 | Z80-Boy | it it like the ray is transformed through the matrix and then shot at the arbn? |
| 21:29.43 | ``Erik | just wanted to note that it might be one eventually |
| 21:29.50 | Z80-Boy | Or the arbn is transformed once and then rays shot at it? |
| 21:31.48 | Z80-Boy | Is this right? |
| 21:31.49 | Z80-Boy | <PROTECTED> |
| 21:31.50 | brlcad | hm, okay .. so it's choked on 16 copies of the entire t62 with every primitive renamed with an 'a' suffix (took about 15 seconds) |
| 21:32.05 | Z80-Boy | Isn't there something missing around the aip->eqn[i][3];? |
| 21:32.24 | brlcad | but at that point, even 'tops' takes about 15 seconds |
| 21:32.36 | Z80-Boy | why is it called norm_dist when aip->eqn[i][3]; is unnormalized? |
| 21:32.40 | Z80-Boy | Or is it normalized before? |
| 21:33.46 | ``Erik | take a shower? |
| 21:35.06 | Z80-Boy | I guess the code is wrong. |
| 21:35.54 | Z80-Boy | does VDOT do just a plain dot product? |
| 21:36.51 | brlcad | iirc, all of the norm() routines assume a normalized vector |
| 21:37.00 | brlcad | so that it doesn't have to check/compute it |
| 21:37.12 | Z80-Boy | this is norm_ variable, not a norm_routine |
| 21:37.14 | brlcad | that was a performance tweak a long time ago that made a big difference |
| 21:37.26 | *** part/#brlcad angasule (n=angasule@190.49.222.207) |
| 21:37.43 | brlcad | where is that line you pasted? |
| 21:37.50 | brlcad | in what routine? |
| 21:37.57 | Z80-Boy | rt_arbn_shot |
| 21:38.15 | Z80-Boy | I guess the last term has to be either divided or multiplied by the length of the plane vector |
| 21:38.24 | Z80-Boy | cause it's possible to enter the plane vectors unnormalized |
| 21:38.36 | Z80-Boy | -or- renormalize the plane vectors after they have been entered |
| 21:38.42 | brlcad | yeah |
| 21:38.47 | Z80-Boy | so that's the bug? |
| 21:38.49 | brlcad | are you running into a different problem? |
| 21:38.58 | brlcad | john had fixed the other one iirc |
| 21:39.03 | Z80-Boy | I am running into a problem that my Ronja holder looks different than it should |
| 21:39.06 | brlcad | that was related to normalized vectors |
| 21:39.10 | Z80-Boy | because I used an unnormalized plane in arbn |
| 21:39.24 | Z80-Boy | which one it was? |
| 21:39.30 | brlcad | i thought it was that one |
| 21:39.32 | brlcad | are you up to date? |
| 21:39.36 | Z80-Boy | this one is the "mirroring arbn produces a different shape" bug |
| 21:39.43 | Z80-Boy | I checked the bugtracker it's still marked open |
| 21:39.49 | Z80-Boy | Checked it today |
| 21:39.58 | brlcad | hmm |
| 21:40.04 | Z80-Boy | and it still compiles Ronja wrong |
| 21:40.07 | brlcad | then maybe confusing it with a differnt one you posted |
| 21:40.11 | Z80-Boy | just did update - it's till in the CVS |
| 21:41.04 | brlcad | k |
| 21:41.26 | Z80-Boy | the VDOT between a shot ray and plane normal produces what exactly? |
| 21:41.31 | Z80-Boy | A projection! |
| 21:44.44 | Z80-Boy | the plane basically stays the same if you multiply all 4 numbers by some constant, right? |
| 21:44.58 | Z80-Boy | ax+by+cz+d=0 |
| 21:45.34 | Z80-Boy | If you do it the VDOT grows by the same constant as the aip->eqn[i][3] |
| 21:45.39 | Z80-Boy | so it shouldn't be a problem |
| 21:45.45 | Z80-Boy | just the norm_dist gets denormalized |
| 21:45.53 | Z80-Boy | so now it has to be divided by the vector length |
| 21:46.16 | Z80-Boy | of the plane normal vector |
| 21:48.46 | Z80-Boy | and then there is a remote chance my holder will look right ;-) |
| 21:54.18 | brlcad | swank |
| 22:01.09 | Z80-Boy | hmm it didn't help, it's the same :( |
