In the previous version, there were mathematical calculation errors, and various corrections have been made. it's getting better but the look has totally changed... #wgsl #webgpu #pathtracer #sdf

my favorite aspect of three-gpu-pathtracer (aside from being a wildly impressive piece of software) is how it implicitly shows you the fidelity delta between rasterization and path tracing every time you render a new frame - an unexpectedly useful educational tool

Wavefront pathtracer now handling both SDF geometry and ray-triangle intersection tests.

Old sonic experiment track "Not a beat 2359" -- sampling the `espeak` speech synth with randomly generated syllables over a beat (the title lied, sorry). The video is fractal meat rendered by my global illumination pathtracer coded in GLSL using artisanal intelligence.

New wavefront pathtracer is now handling diffuse bounce behavior. Foveated offsets using this interlacing scheme I've been playing with gives it an interesting look, more detail towards the center.

Reviving my realtime RT DI/GI project for the 7th time.
Screenshot is of the reference pathtracer I put together to ensure my scene binding/TLAS code was all working.
It's not particularly clean or performant on the CPU-side, but I can start experimenting with the GPU-side research now :)

been a couple years since I wrote a dumb pathtracer-in-a-shader; felt that itch again and decided to brush off the cobwebs by 'covering'/'blatantly ripping off' noby's brilliant 10yo 4k www.youtube.com/watch?v=9r8p...

Made some further improvements. The darker scenes seem to have better quality...
The output looks nice, i'm gonna try various SDF shapes #wgsl #webgpu #pathtracer #sdf

only after getting wasted do i suddenly start heavily plotting out the technical design for a performant slit-scan-based spectral pathtracer for that old funny SSTV game prototype of mine, wtf
(pic is old but relevant to this project i'm picking back up)

It's been some time. I've been working on a 2v2 map for CounterSitrke on my free time. Now I'm starting the detailing pass. These textures are for debug purposes and to familiarize myself with the material editor. From Substance Designer to Source 2 engine.

Soooo once I'm done with the pathtracer for now (which is gonna be real soon) do I return to my main game project or do I try to make a realtime voxel GI pathtracer 🤔🤔🤔
Somehow new year is consistently the time when I feel the sudden urge to do some purely graphics stuff

Makes debugging way easier: move the camera until you see a rendering error, a firefly; click on that pixel and see the path producing the issue. In most cases I can re-run the pathtracer on the CPU on that light path with the debugger, or printf on the GPU just from that light path.

This was built pre-locomotor and was a bit of pain to get set up. You had to spin the joystick around to cycle the legs haha
Super fun to build though! All rendered in Unreal using the pathtracer for Emefe's new album (check them out!) emefe.bandcamp.com/album/forward
