The WebGPUPathTracer branch is finally merged! With upscaling and denoising supported. Initial release coming tomorrow! But for now check out a demo here ✨ gkjohnson.github.io/three-gpu-path… #threejs #webgpu

Trying more complicated scenes. Radiance Cascades does all lighting here: sub-surface scattering, caustics, volumetric multiple scattering (64 orders), and iridescence. Because the simulation is spectral, there is no approximation or fit for thin-film interference or iridescence.

Experimenting with a multi-level cache for high-frequency effects based on my previous work for SPWI surface GI (left). Specular effects like caustics scale in 2D on surfaces. Also researching solutions to angular aliasing and flickering of depth-upscaled probes (right). No TAA.

I reverse engineered and reimplemented DLSS 5's neural rendering in Vulkan, from the architecture down to the last rounding. same input, same output as Nvidia's DLSS5, 7.8ms per 1080P on RTX 4070 super code and docs : github.com/maanHimself/Op…

new wip vulkan renderer. global illumination using sparse radiance cascades and a z-buffered environment map. emissives only, no noise, no temporal accumulation, no ray tracing. i have learned an awful lot this year i hope i can find a JOB. and goodness gracious box3d is so good

An extension of Radiance Cascades global illumination to support complex transmissive and reflective light transport, including diffuse and specular reflection, refraction with dispersion, caustics, and subsurface scattering. Left: U-HRC (32^3), Right: spectral path tracer

@0xC0DE6502 The puzzle here is not: cheese -> mouse -> elephant. 3 mice at an opticians means play the Three Blind Mice melody on an organ across the map.

Google solved consistent hashing in just 5 lines of C++ John Lamping and Eric Veach designed it to map keys to buckets with almost no memory when a bucket is added, only about 1/n of the keys move the entire algorithm is a tiny loop using a 64-bit LCG and the constant 2862933555777941757ULL O(ln n) expected time, O(1) memory

Most code assumes cache lines are 64 bytes. but that’s a bad assumption on hardware with wider lines. C++ gives you std::hardware_destructive_interference_size specifically to avoid false sharing without hardcoding a cache line width.

I’m happy to announce the release of a new open source 3D physics engine called Box3D. I’ve been working on this project for a few years now, but it represents over 20 years of experience writing physics engines for games. Read more here: box2d.org/posts/2026/06/…

You can't engineer luck. Cleanest phrasing of P vs NP I've heard. NP is the magical computer that always tells you which path to take. P is what current silicon can do. Tetris is NP-complete. Chess is EXP-complete. MIT 6.006 Introduction to Algorithms, Fall 2011.

Someone just open-sourced a desktop app that generates 3D models from images and runs 100% locally. It's called Modly. Drop in an image, it generates a fully textured 3D mesh on your own GPU. No cloud. → Photo to 3D mesh in seconds → Runs 100% locally on your GPU → Pluggable AI model extensions → Windows + Linux
