| 01:31.32 | starseeker | don't faint ;-) |
| 01:31.51 | ``Erik | but if I do, then I can hit my head and have a reason for not showing up tomorrie :D |
| 01:32.15 | starseeker | aw, but then you won't get to see my annoying marching cubes email |
| 01:32.30 | ``Erik | O.o |
| 01:32.44 | ``Erik | dare I ask? |
| 01:33.21 | starseeker | probably asking stuff you've already though about - octrees |
| 01:33.54 | ``Erik | for marching cubes? you're probably talking about an approach to the subdivision stuff I was talking about... |
| 01:34.45 | starseeker | I think gqa could benefit from the application of similar ideas, just using volumes rather than the marching cube face logic |
| 01:35.03 | ``Erik | but knowing when to subdivide would be a trick, there's the risk of geometry passing through a 'cube' without hitting a vertex of the cube, so the algorithm will assume there's no geometry in it |
| 01:35.12 | starseeker | we do quad subdivision on nurbs, and octree subdivision of volumes is the 3d version of that |
| 01:35.26 | ``Erik | yes, I'm well familiar with quadtrees and octrees |
| 01:35.34 | starseeker | I was talking with Ed about that earlier |
| 01:35.39 | starseeker | have a couple ideas |
| 01:36.37 | ``Erik | isn't sure it actually is a benefit to g_qa, the locality thrashing may offset any meager benefit |
| 01:36.50 | starseeker | depends on how dense a grid you fire |
| 01:37.26 | ``Erik | you're basically guaranteeing a cache miss every time with the current approach, I think... |
| 01:37.28 | starseeker | or rather, need to fire |
| 01:37.54 | starseeker | gqa's current approach? |
| 01:38.01 | ``Erik | yeh, it hops all over the place |
| 01:38.07 | starseeker | mm |
| 01:38.30 | ``Erik | and I'd imagine that most of the cost is cache related anyways... *shrug* |
| 01:38.38 | ``Erik | hit it with shark :D |
| 01:38.52 | ``Erik | then redo it to just shoot a regular grid and compare that |
| 01:39.04 | starseeker | well, if you're in tomorrow and have a few minutes I'd like to outline what I'm thinking octree wise |
| 01:39.26 | starseeker | if nothing else, you get a chance to shoot down one of my ideas and you know how much fun you have doing that |
| 01:39.32 | starseeker | :P |
| 01:39.44 | starseeker | almost as good as making fun of me being stuck in the mud |
| 01:39.51 | Nohla | holas |
| 01:40.16 | starseeker | hola :-) |
| 01:40.17 | ``Erik | octrees even lost ground to kd-trees back when cpu's were much slower *shrug* |
| 01:40.35 | ``Erik | they were the rage for outdoor game crap way back when, though |
| 01:40.43 | starseeker | nods |
| 01:40.43 | ``Erik | um, along with ROAM for big terrains heh |
| 01:41.10 | ``Erik | then hoppe did his shtuff |
| 01:41.46 | ``Erik | (yeah, I know... wtf, something good from microsoft? obviously their research facility is on a different planet hten their product development, corporate, legal, etc stuff) |
| 01:41.56 | starseeker | has notice that before |
| 01:42.07 | ``Erik | VIPM was nifty at the time, though |
| 01:42.29 | ``Erik | s/hten/than/ |
| 01:42.39 | ``Erik | evening, nohla |
| 01:42.55 | starseeker | well, don't want to waste time if it's a useless idea |
| 01:43.03 | ``Erik | trapped like carrots, heh |
| 01:43.07 | starseeker | hopes he hasn't forced ``Erik to explain it to Ed... |
| 01:43.22 | Nohla | ``Erik good day, for the hole day :) |
| 01:43.53 | ``Erik | well, it'll probably go something like... <ed> so what's this cliff was saying about octrees? <erik> that's the adaptive refinement we talked about. <ed> ah |
| 01:44.10 | starseeker | heh |
| 01:45.16 | ``Erik | unless this demo thingy puts me in a mood, then I might say "heh, yeah, cliff found an ancient technique we all ditched and is pretending to be a coder" :D *duck* |
| 01:45.58 | starseeker | sigh - I do feel like that on some days |
| 01:46.13 | ``Erik | hehehe, naw, just different background :D |
| 01:46.26 | ``Erik | you were doing... math... for fun... when I was studying all the video game fu |
| 01:46.32 | starseeker | heh |
| 01:46.44 | starseeker | I just didn't have access to video games or computers |
| 01:46.54 | starseeker | shudders to think how messed up he would be if he had |
| 01:47.10 | ``Erik | I mean, proofs instead of quaternions? srsy? |
| 01:47.44 | starseeker | ``Erik: so kd-trees were the successer to octrees? |
| 01:48.06 | ``Erik | they were the successor to b-trees |
| 01:48.27 | starseeker | ah |
| 01:48.46 | ``Erik | but 3 kd-tree stages tended to be quicker than a single octree stage for most video game crud |
| 01:49.09 | ``Erik | and what's his name wrote articles about portal/sector at about the same time, which was teh awesomez |
| 01:49.20 | ``Erik | h-something on, uh, gamedev.net? |
| 01:49.25 | ``Erik | havok? |
| 01:49.32 | starseeker | oh, the Id guy? |
| 01:49.48 | ``Erik | dunno |
| 01:50.04 | ``Erik | shoot, what was the name of that site... black background and orangish text |
| 01:50.14 | starseeker | are you using kd-trees for the marching cubes stuff then? |
| 01:50.35 | ``Erik | no |
| 01:50.52 | ``Erik | first version is going to be regular grid walked linearly |
| 01:51.05 | ``Erik | I'm not sure subdivision approaches would be acceptable :/ |
| 01:51.31 | ``Erik | for the same reason the metaball ray "tracing" is flakey |
| 01:51.55 | starseeker | missing small features? |
| 01:52.02 | ``Erik | yeah |
| 01:52.21 | starseeker | my suggestion to Ed was to use the bounding box hierarchy of the CSG primitives |
| 01:52.24 | ``Erik | the 'small'ness of the feature is the size of the first sample subdivision |
| 01:52.38 | starseeker | unlike metaballs, we have some extra information we can use |
| 01:52.47 | ``Erik | possibly |
| 01:53.05 | ``Erik | but it's all irrelevant until I figure out how to shove triangles into an nmg :D |
| 01:53.12 | starseeker | octree seemed to lend itself to that... |
| 01:53.13 | starseeker | heh yeah |
| 01:53.22 | starseeker | that's wacky |
| 01:53.31 | ``Erik | the schedule has a wad of time at the end for exploring optimizations |
| 01:53.46 | starseeker | remembers being scared of that early on - looks like I was right to fear ;-) |
| 01:53.50 | ``Erik | no need for premature optimizations :) |
| 01:57.00 | ``Erik | heh /* implement me */ ... that helps |
