Sparse Voxels Rasterization: Real-time High-fidelity Radiance Field Rendering

A novel approach for rendering radiance fields using adaptive sparse voxels and rasterization, achieving high-fidelity results at over 100 FPS without neural networks. The method introduces efficient voxel allocation across different detail levels and implements a custom rasterizer using ray direction-dependent Morton ordering, eliminating common rendering artifacts.

A detailed explanation debunks the common misconception about GPU branching optimization, specifically addressing how ternary operations and if statements don't actually create conditional branches in modern GPUs. The article demonstrates through machine code examples that using step() and mix() as optimization alternatives actually leads to slower performance.
