RGB rendering is founded on lies and perpetuated by misconceptions about the practicality of spectral rendering. My new blog post series describes a spectral GPU path tracer. Part 1 focuses on how to make it work with existing RGB assets.

Gigi Version 1.01.5 Released

The big items:
* Indirect Draw (GPU driven rasterization)
* AMD FFX Upscaling /Frame Generation
* Variable aliases for shaders (~push constants)
If you want to play around with the FSR stuff, there's a "AMD FSR" technique in the Gigi Browser.

Demo of bilinear interpolation of SDF samples:
- Negative (interior) samples of the analytic SDF are blue, positive (exterior) samples are orange.
- Circles are drawn around samples to show distance magnitude.
- Intermediate bilinear interp samples / segments are drawn.

The experiments with surflets and voxels yielded some cool results, but it became quite obvious that distance fields were the way to go to represent the surface of morph objects (as I alluded to previously). This allowed us to implement some visually neat effects like this twist transition.

Ray marching is a common approach to GPU-accelerated volume rendering, but gives biased transmittance estimates. My new #SIGGRAPHAsia paper (+code) proposes an amazingly simple formula to eliminate this bias almost completely without using more samples.

A couple barriers to C development are lack of a fast sorting library and a fast hash set and map. I've found these two libraries to be excellent at providing those. They are macro based, but I think the trade-off is worth it. Both work with C99.

🙈 Just as Transformers learn long-range relationships between words or pixels, our new paper shows they can also learn how light interacts and bounces around a 3D scene.

So, I made a hair shader that doesn't require any specially made meshes or textures.
Initially I made this work by sampling many normal directions rotated around the hair strand direction, but I eventually got an approximation working that doesn't rely on multi-sampling.
