Here's a thread for sharing renderings that people make involving either BRL-CAD geometry models or BRL-CAD rendering. Feel free to post your own pictures.

To kick things off, here's a rendering I made a few months back: t62.png

I don't remember exactly, but this image has pretty much all the knobs turned all the way up, so it was computationally intensive and rendered at a ridiculous resolution for a huge poster printing. I believe it was 16384x16384 with hypersampling (don't recall exact setting but probably -H3), shadow rays (300 sample rays per hit if I recall correctly), and ambient occlusion (forget how many samples, but it was a lot too!). Basically, in the "trillions of rays" ballpark. I should calculate the actual. Regardless, rendering with remrt took something like 4-8 hours using over 300 cores. The poster looks amazing. ;)

Really need to get ambient working with rt's cutting plane option... Screen-Shot-2020-08-27-at-12.46.23-AM.png

This building render turned out pretty nice, though. Wow, this is an oldie! building_1024.png

the building looks cool

Sumagna Das (Aug 27 2020 at 06:43):

Did you make it in BRL-CAD?

Sean (Aug 27 2020 at 18:43):

@Sumagna Das yes, that's a pure BRL-CAD model made from scratch

Sean (Aug 27 2020 at 18:45):

that was 14 years ago though, and my memory of who all worked on it is fuzzy. I remember directing and coordinating a lot, but I think there was a summer student or two involved in taking measurements and creating the geometry. I put the scene together, created and textured the ground, and rendered it.

Improved ambient occlusion support for cut planes.. before and after:

Cool. This sampling method converges to a very precise surface area metric in a fraction of a second:

Somewhat better view of what's going on...

Testing out three different methods for visualizing a model's exploded complexity in a collage format:

(All three are incomplete, still running as those are just previews -- full res is print-quality)

Hah - wacky cool

Sean (Sep 11 2024 at 21:56):

There was a really cool collage I saw at Siggraph that gave me the idea. Still have to pad the images better and probably cull out negative cuts, but idea is to spread it all out in one image.

starseeker (Sep 12 2024 at 13:30):

Reminds me of that old "exploded views" paper from siggraph years ago

starseeker (Sep 12 2024 at 13:31):

I think it was this... https://grail.cs.washington.edu/projects/exview3D/
