| 01:43.55 | CIA-7 | BRL-CAD: 03brlcad * 10brlcad/src/tclscripts/ (ami.tcl ampi.tcl): heh, there's quality control for ya.. check for existance of variable name so we actually do some work.. |
| 01:43.57 | brlcad | aborting is just a rude way of error'ing |
| 01:44.31 | brlcad | it should be more graceful about it though, yeah |
| 01:44.39 | IriX64 | agreed |
| 01:44.46 | brlcad | to fix it, look at the file dsp loading code |
| 01:44.59 | brlcad | src/librt/g_dsp.c .. match it to the abort error message you get |
| 01:45.36 | IriX64 | g_dsp.c line 3134 ive looked. |
| 01:49.37 | brlcad | if you "cd db" from inside the source tree, it should find its data file |
| 01:51.00 | IriX64 | after i bring up mged you mean, and load it from within "db"? |
| 01:52.06 | Maloeran | brlcad, Erik, can I assume zlib is not an unreasonable required dependency? |
| 01:52.30 | brlcad | Maloeran: it's already one |
| 01:52.34 | brlcad | (to brl-cad) |
| 01:52.44 | brlcad | so no, not at all ;) |
| 01:52.52 | Maloeran | Oh. :) |
| 01:53.16 | brlcad | pretty much anything like zlib that has zero dependencies of it's own are usually unreasonable |
| 01:53.51 | brlcad | or if the dep is just something like zlib with no deps of it's own |
| 01:55.55 | Maloeran | Usually unreasonable? |
| 01:55.56 | Maloeran | Just making sure you didn't intend to type "reasonable" instead |
| 01:55.56 | brlcad | other similar deps we currently already have, libpng, zlib, libregex, and termlib (not full-blown curses) |
| 01:55.56 | brlcad | er, yeah .. reasonable |
| 01:56.04 | IriX64 | will try it soon as this make install is done brlcad. |
| 01:56.24 | Maloeran | I can keep it optional, but if won't go nicely if processing nodes are compiled with/without it, without further handshake tests anyway |
| 01:56.36 | brlcad | something like gtk sit at the other extreme .. dependency hell |
| 01:56.51 | *** join/#brlcad louipc (n=louipc@bas8-toronto63-1177707015.dsl.bell.ca) |
| 01:57.03 | brlcad | zlib is trivial to use, no reason not to other than technical benefit |
| 01:57.09 | Maloeran | Nevermind actually, I'll keep it optional, I really prefer to keep dependencies to a minimum |
| 01:57.20 | brlcad | what are your deps currently? |
| 01:57.26 | louipc | Maloeran: cool vids ;) |
| 01:57.31 | brlcad | sdl's a fairly heavy one for keeping them to a minimum :) |
| 01:57.42 | Twingy | on my system I take make; make install and gtk isn't much of an issue :) |
| 01:57.52 | Maloeran | The engine : nothing but C99 and pthreads. The demos : SDL |
| 01:58.03 | Maloeran | Thanks louipc :) |
| 01:58.04 | brlcad | that's not too shabby |
| 01:58.05 | Twingy | I suppose anything is dependency hell if you have a crappy package system |
| 01:58.23 | Twingy | i.e. irix freeware |
| 01:58.30 | Twingy | i.e. redhat rpms |
| 01:59.05 | Maloeran | The video recording demo doesn't require SDL clearly, but I prefer some visible interactive output ;) |
| 01:59.06 | brlcad | which is the reality of being and caring about cross-platform |
| 01:59.16 | brlcad | if you don't care about that, then .. sure, not an issue |
| 02:01.46 | Maloeran | By the way brlcad, I found how to add proper N buffering support in SDL, but I don't think my patch would be accepted. It would be a mess to require a patched SDL too |
| 02:02.56 | brlcad | never know till you submit ;) |
| 02:03.07 | brlcad | i'd like that feature myself |
| 02:03.38 | brlcad | probably more of doing the patch in a way that is clean to the API |
| 02:04.42 | Maloeran | Easy : just provide a function to replace the "shadow" surface of any screen surface with another identical in size and format. The previous shadow surface becomes an independent surface |
| 02:06.45 | IriX64 | brlcad: tops reports mapped file open failed twice but it did do the list. |
| 02:07.15 | brlcad | so replace shadow with a pointer into an array, and add an API function to attach additional SDL_Surfaces (which just add to the array) like SDL_AddFlipSurface() |
| 02:07.41 | brlcad | then SDL_Flip just rotates the pointer through the array |
| 02:08.00 | brlcad | should be neat n clean enough to accept unless someone has moral objections to it |
| 02:08.01 | Maloeran | Rotation is not good enough, I must be able to hop erratically |
| 02:08.22 | Maloeran | Replacing the shadow surface is clean really, just changing one little pointer |
| 02:08.41 | brlcad | so add another that is SDL_SetFlipSurface() too, but let default just rotate or somesuch |
| 02:09.01 | brlcad | yeah, but that exposes an internal .. I can't see them accepting that |
| 02:09.48 | Maloeran | There's a function around it. SDL_SetShadowSurface( SDL_surface *shadow ); |
| 02:10.06 | Maloeran | The previous shadow/screen surface becomes a regular surface at that point, very simple |
| 02:10.18 | brlcad | so they already have the func |
| 02:10.25 | Maloeran | No :), that's mine |
| 02:10.33 | brlcad | ah.. hmm |
| 02:11.37 | brlcad | maybe they'll take it just like that, though they might not like the name if "Shadow" surfaces aren't exposed anywhere else |
| 02:12.01 | Maloeran | SDL_SetScreenSurface() might be more appropriate |
| 02:12.03 | brlcad | but that's easy enough to change if that's their only gripe |
| 02:12.16 | brlcad | go for it ;) |
| 02:12.37 | Maloeran | Now, I need to learn how to make a patch! :) I think it involves diff |
| 02:12.41 | brlcad | talked to any of the devs about making the change? |
| 02:12.42 | brlcad | hah |
| 02:12.45 | brlcad | serious? :) |
| 02:13.19 | Maloeran | Initial reply from dev was "I don't think it would be something we'd add to SDL itself" |
| 02:13.35 | brlcad | diff -u file > mymod.patch |
| 02:13.50 | brlcad | er diff -u fileold filenew > mymod.patch |
| 02:14.52 | Maloeran | Thanks |
| 02:15.51 | Maloeran | If multiple files were modified, can I append all the "diff" to the same patch? |
| 02:16.06 | louipc | :O |
| 02:16.09 | IriX64 | brlcad: aclocal-1.8.5/automake-1.8.5 fixes that syntax error in config bug. |
| 02:16.27 | louipc | Maloeran: yep |
| 02:16.29 | brlcad | diff -r -u dirold dirnew if you have entire directory differences, or even better ... cvs diff -u > mod.patch |
| 02:17.30 | brlcad | might want to add -b -B if you inadvertently changed whitespace too .. that's usually annoying to include with feature patches |
| 02:17.57 | brlcad | (never hurts, just means ignore differences in whitespace) |
| 02:18.03 | Maloeran | All right, thanks |

| 17:33.38 | ``Erik | (that woulda been MUCH faster if it were commented) |
| 17:41.47 | Maloeran | Of course it's balanced |
| 17:42.15 | Maloeran | Well kind of, it maintains the tree balance within good limits |
| 17:42.43 | ``Erik | 'within good limits'? :D |
| 17:43.02 | Maloeran | The most expensive branch can never be twice longuer than the shortest |
| 17:43.09 | Maloeran | And typically, the average is fairly good |
| 17:44.24 | Maloeran | I'm impressed you managed to make sense of the code :) |
| 17:46.46 | ``Erik | heh, it was rough and I still don't grok parts of it :) |
| 17:47.11 | ``Erik | some notional comment of what MM_BTREE_FLAGS_STEP is would make it a lot easier to read |
| 17:47.44 | ``Erik | and the naming convention makes things rough... 'anode' where I may've used 'ancestor_n' |
| 17:47.49 | Maloeran | It's a marker to recognize patterns in the tree structure |
| 17:49.27 | ``Erik | yeah, but that's one that's highlighted all through the insert ufnction on my printout as I was trying to 'solve' it :) |
| 17:50.02 | Maloeran | :) I think it's kind of elegant, very efficient |
| 17:50.36 | Maloeran | And the worst, rare case ( longuest twice as long as shortest ) is not too bad |
| 17:51.11 | Maloeran | So anyway, it's surely nothing new, but putting a name on the balanced binary tree could be nice |
| 17:51.57 | ``Erik | it's not really balanced, though, the min and max tree dpeth differ by more than 1 in cases |
| 17:52.35 | Maloeran | Of course. The point is high performance with a very much acceptable "worst case", it's not a perfect balance |
| 17:52.54 | Maloeran | Getting a perfect balance constantly is way too expensive, performance is the objective here |
| 17:53.55 | ``Erik | *shrug* well done avl's and rb trees are pretty fast, there was another one that stored dpeth at each node and rotated on the way down to maintain balance, I forget its name, though |
| 17:54.06 | ``Erik | I know it had lightening bolts on the diagrams in the MIT book :D |

| 19:41.02 | IriX64 | or do you mean asc2g? |

| 19:42.34 | IriX64 | ill see what i can do. |
| 19:43.22 | brlcad | then basically just ending up with a list/table of the geometry files in db/ and for each top level object, reporting whether g-whatever succeeded fully, partially, aborted abnormally, or outright crashed |
| 19:43.42 | brlcad | heck, if you did it for all the converters, that would be freaking sweet |
| 19:54.35 | IriX64 | tell you right now somethings wonky with g-dxf or dxf-g i translated to dxf and then used dxf-g and something got lost in the translation. |

| 23:26.19 | IriX64 | found where the error message is coming from. |
| 23:26.53 | brlcad | yes, so it's checking if the mapped file is valid, and aborting |
| 23:27.14 | IriX64 | looks like it. |
| 23:27.23 | brlcad | it should recognize earlier that the mapped file is invalid and terminate more gracefully |
| 23:27.33 | brlcad | the trick is where in g_dsp does it abort? |
| 23:27.41 | IriX64 | does that routine get called on every file, it must no? |

| 23:29.37 | brlcad | ``Erik: don't know how many papers you have on the subject, but there were some great ones last year on tessellation of arbitrary implicit surfaces using particles that is impressive |

| 23:41.59 | brlcad | avoiding the check isn't interesting .. it aborts there correctly |
| 23:42.21 | brlcad | the point is to find where in g_dsp that it is aborting, detecting that situation beforehand and just returning a failure instead |

| 23:44.24 | brlcad | ray shot hack is undoubtedly a variation of marching cubes to make it work |
| 23:44.40 | ``Erik | kinda sorta almost, I suppose |
| 23:44.45 | IriX64 | got that line 3134 in dsp_g.c |
| 23:44.50 | ``Erik | lee's answer to every geometry problem is to shoot rays through it and approximate |
| 23:44.54 | brlcad | the particles stuff is impressive |
| 23:44.58 | brlcad | and instant |
| 23:45.17 | IriX64 | err g_dsp.c |
| 23:45.24 | ``Erik | I grabbed the newer paper you pasted |
| 23:45.28 | ``Erik | is it worth grabbing the older one? |
| 23:45.42 | brlcad | IriX64: ah, hm, interesting |
| 23:45.58 | brlcad | yeah, the older is the basis for the newer |
| 23:46.09 | brlcad | hart is like the main implicit surfaces guy in the field |
| 23:46.12 | ``Erik | ok, wgot. |
| 23:46.22 | brlcad | http://graphics.cs.uiuc.edu/~jch/papers/ |
| 23:46.33 | brlcad | he's got tons of interesting stuff of relevance |

| 23:49.03 | brlcad | you've seen hart before, he's almost always presenting or organizing at siggraph |
| 23:51.17 | ``Erik | if I say in a session he's spoken at before... I've only been to one siggraph |
| 23:51.37 | ``Erik | and I was pretty heavy on fluid dynamics at that one |
| 23:51.43 | ``Erik | a bit on high perf rt |
| 23:51.46 | brlcad | ahh, that's right |
