Current progress on my Bitonic sort obsession, compared against GPUSorting's OneSweep implementation (github.com/b0nes164/GPU...) as a reference

32-bit keys only. Tried to pick the best tuning parameters for the OneSweep reference to steelman the comparison

In HLSL, calling
GoldNoise(DispatchThreadID.xy, 1.0)
produces NaNs for certain values of DispatchThreadID.xy, e.g. (994, 581).

It doesn’t happen when I pass constant values, so it seems to occur only for non-uniform inputs ?🤔?

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Our #SIGGRAPHAsia 2025 paper "Sample Space Partitioning and Spatiotemporal Resampling for Specular Manifold Sampling" improves #realtime #caustics rendering.

Left. The dominant axis is x. We first translate the ray along its direction vector such that the transformed ray’s origin o coincides with the subspace spanned by the other, non-dominant axes (only y in this 2D-example). Scaling the direction vector by 1/dx the x-component of the transformed ray’s direction d becomes 1. Now the intersection ray parameter with the near and far plane along the x-axis directly corresponds to the bounding box coordinates bminX and bmaxX without any further computations required

Axis-Normalized Ray-Box Intersection
"By transforming the ray we eliminate the need for one third of the traditional bounding-slab tests and achieve a speed enhancement of approximately 13.8% or 10.9%"
