TODOs

General

• GitHub CI

GLSL

• Packed types for material struct alignment
• Parallelize TLAS builder
• Find a better way to orthonormalize directions.
• Find a scale-dependent offset of ray origins to avoid self-intersections. (Ray Tracing Gems Chapter 6)
• Implement path regularization to address fireflies. Currently, I use clamping. (Ray Tracing Gems Chapter 17)
• Fix BVH. Crashes for some scenes.
• Add accumulation buffer.
• Fix RNG
• Implement low-discrepancy sequence samplers
• Implement SAH as BVH split function.
• Fix BVH memory consumption. BVH copies vertex/index data from Scene.
• Flatten BVH as DFS for (potentially) better cache coherence.
• Improve SSBO alignment. Renderer copies vertices with 1 empty float buffer to align vec3s to vec4s.
• Implement render modes (Albedo, Normal, Depth, BVH)

Metal

• Custom intersection function for alpha testing
