| 22:18.27 | brlcad | starseeker: any reason to shove mged.tar.gz in as a tar.gz or just mimicking the shell archive? |
| 22:18.53 | starseeker | uh, not really - wasn't sure offhand how to do the shell archive |
| 22:19.11 | starseeker | wasn't really cleary why it was an archive at all, to be honest... |
| 22:19.11 | brlcad | really? :) |
| 22:19.13 | brlcad | "shar" |
| 22:19.24 | brlcad | old old tool |
| 22:19.31 | starseeker | mans shar |
| 22:19.51 | starseeker | huh - cool |
| 22:20.32 | brlcad | there's no reason mged.sh is a shar either |
| 22:20.44 | brlcad | was more CVS deficiencies handling binary data |
| 22:20.53 | starseeker | ah |
| 22:20.57 | brlcad | certainly don't need both |
| 22:21.09 | starseeker | I'll try making a new shar first |
| 22:21.15 | starseeker | replace the old one |
| 22:21.16 | brlcad | maybe a latex2docbook? |
| 22:21.26 | brlcad | then get rid of the old ones |
| 22:21.50 | starseeker | maybe... there are a truckload of eps files in there... dunno if they're all gonna convert well |
| 22:22.21 | starseeker | let me try the shar now - I'll probably need my gentoo box to get all the requisit tools for a serious docbook conversion attempt |
| 22:24.59 | brlcad | keep them as eps |
| 22:25.19 | brlcad | or convert them to svg |
| 22:25.49 | brlcad | some of them are undoubtedly just image data and can be png |
| 22:26.05 | brlcad | anything vector should become an svg though |
| 22:26.39 | starseeker | winces - looks like my ps2ps usage drastically increased the size of some of these - I'd better restore the originals |

| 22:53.54 | brlcad | heh, pretty good! |
| 22:54.32 | ``Erik | the barbie commercial made it look reasonably interesting O.o :D |
| 22:54.43 | brlcad | did a great job with the 3d |
| 22:55.32 | ``Erik | on par with avatar? (sans motion sickness?) |
| 22:57.38 | ``Erik | I'd read that after avatar, the studios scrambled to "add" 3d to films coming out that were filmed in 3d in a shoddy fashion, I'd imagine pixar has the insane renderfarm unf where they could at least re-render to get stereoscopic, but were the scenes arranged to take any kind of real advantage? (IE: useful, not gimmicky) |
| 22:59.06 | ``Erik | (hm, ~115 minutes, 24fps, ~2750 frames, not TOO much) |
| 22:59.33 | brlcad | more subtle than avatar |
| 22:59.55 | brlcad | a lot more, less "glitter", but added nice depth |

| 23:04.05 | brlcad | would have to at least clean up a tutorial |
| 23:04.19 | brlcad | to show them how to do some of the basics |
| 23:04.21 | ``Erik | *ponder* hoist the bezier solver, add some kinda keyframe info and fitting, mebbe some gui work to make it usable... |
| 23:04.38 | brlcad | that all exists in mged now |
| 23:04.56 | brlcad | just no docs for it |
| 23:05.15 | ``Erik | the movie stuff I was doing, I was just writing a for `jot` loop to raytrace, convert to png, then run ffmpeg on the set of images at the end |
| 23:06.01 | ``Erik | for anything other than moving the camera in a static scene would require a prep for every frame, though |
| 23:06.12 | brlcad | yep |
| 23:06.35 | brlcad | that's where src/anim and the mged stuff helps, you specify keyframes and it'll interpolate the intermediates |
| 23:12.54 | ``Erik | nifty, linear or bezier spline? |
| 23:13.49 | ``Erik | the lightwave 4 scene manager was good fun to play with, making the curves and getting animations :) |

| 23:14.14 | brlcad | options for both |
| 23:14.21 | brlcad | cubic splines too iirc |
| 23:14.40 | ``Erik | anim_time yeah |
| 23:15.58 | ``Erik | anim_script looks like the big hammer |
| 23:20.52 | ``Erik | hrm, yeah, it does a "clean" between frames, even if the scene itself doesn't change :/ |
| 23:21.29 | ``Erik | given that we have geometry requiring more prep time than raytrace time, that might need to be fixed eventually |
| 23:44.42 | brlcad | I'd be surprised if prep actually is longer than render time for something actually modeled to look good, especially once you just add a couple custom lights with realistic shadows |
| 23:45.12 | brlcad | not to mention oversampled HD-quality video frames |
| 23:46.00 | ``Erik | well, for a 512x512, the uh, geometry I like to show off the TIE stuff with is a heck of a prep |
| 23:46.18 | ``Erik | and I'm kinda in the 320x240 video mindset, not 1080 :D |
| 23:46.27 | brlcad | that's crap video :) |
| 23:46.29 | ``Erik | yeah |
| 23:46.51 | ``Erik | but ffmpeg's default is highly compressed mpeg, and I haven't found a way to make it not suck yet |
| 23:47.07 | ``Erik | so why cook cpu on accuracy that'll be thrown away in the assembly? |
| 23:47.58 | ``Erik | there're a few models that sit and churn a long time on prep before a fairly fast raytrace... usually with buttloads of bots |
| 23:48.08 | brlcad | 1920x1080 video should ideally be about 7680x4320 -j2 -H3 render frames so you can downsample nicely |
| 23:48.59 | brlcad | should do well to eliminate temporal aliasing too |
| 23:49.06 | ``Erik | 16x pixel oversampling plus 4x per pixel sampling? 64 pixels per end pixel? |
| 23:49.25 | brlcad | mm |
| 23:51.45 | brlcad | that was just 4x oversample with 3x per pixel, so you have enough samples to sample a jittered average, so 12 rays per pixel |
