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.

When you design data structures, always think in cache lines (64B or 128B). You don't want to have tiny nodes scattered around the memory. Often it's better to have wider nodes (preferably 1 cache line each) and shallower structures. Less pointer/offset indirections.

HairGS: Hair Strand Reconstruction based on 3D Gaussian Splatting (#BMVC2025) 📢
We reconstruct realistic 3D hair strands from multi-view images in ~1 hour. Results show robustness to a wide range of hair styles such as challenging curly hair.

@JarkkoPFC was talking about our lighting solution at SIGGRAPH last night (yesterday in USA). UE5 team was also talking about their Megalights tech. Going to be interesting to compare the technologies.

New at #SIGGRAPH2025:
Can we make Perlin Noise stretch along some underlying vector field? Well it turns out it's possible with two simple additions to the original method! No need for advection or convolutions.

First bits of Nanite Foliage in UE5-Main today including Voxel distance representations, some quick testing the perf increase in my scene is insane, 2x fps and looks much more dense too!
