To reduce the number of ray-marching steps needed to find the surface of our morphs we generate a proxy from the constituent meshes. It must fully enclose the morphed surfaces while remaining as tight as possible to maximize throughput. We want to minimize the red and blue regions in the debug view.

Gigi Version 1.01.5 Released
github.com/electronicar...
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.

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.

Spent some time trying to do conservative culling of geometry for distance function evaluation. Turns out I ended up reinventing something like GJK (which I really have no clue about or experience with) with exact bounds.

How much resolution is required for SkyVisibility Octahedron Probe?
Is something like 6x6 sufficient?
