Coding from a public library, as one does. Is nice!

@aras @gob This picture has all the hallmarks of being a nice render: wooden flooring with specular highlights, no one in sight, multiple copies of the same book, giant plant indoors, bright colored fabric sofas, wide FOV, perfectly straight, flat furniture with emissive strips, nice trees outside, etc...
The floor light does have a switch and is probably plugged in, that's a rare nice touch.

Still trying to implement proper transparent bsdf in my raytracer (instead of hard-coding the refraction ray). Multiple sources and implementations use different formulas and neither of them works 😆

Also I have no idea what's happening on the screenshot

@lisyarus Looks like self intersection? Where you need to move the origin of the ray away from the intersection point in the direction of the bounce (so differently for reflection vs refraction).

Implemented a proper brdf (Cook-Torrance + GGX) and vndf sampling, now I can do some nicer materials! Here's a shiny ball and a golden dragon:

@lisyarus Very nice!
Do you have plans for loading significantly larger scenes? Are you anticipating issues there?

llemarie,
@llemarie@mastodon.gamedev.place avatar

@lisyarus one significant concern is memory. Will you manage to load the new Sponza scene?
I’ve played with the Moana Island scene, that’s a challenge I’ve not conquered yet (: The best I’ve done so far is untextured with missing instances, and that was still 100GB of memory. Lots of optimizations required.

Quick renders of the Sponza scene as voxels of arbitrary shapes (spheres for now).

Cube voxels are also easy.
Now what non-trivial shapes could be interesting for voxels?

@aeva Awesome! Will check it out (:
How about "fractxels" then?

@aeva I do have plans for that. I already support multi-level instancing, so in theory it's not much work.
Then it would look like this (: https://fosstodon.org/@tylermorganwall/112201808515391782
