nightpeak

A 3D game engine I wrote in Rust, and four places I built with it: a lounge, a diner, a manor and a mountain road.

Rust / wgpu / WGSLOpen project
A lounge with a lit checkerboard dance floor, red curtains and a sunset on the stage screen.
A manor at night with every window lit, in the snow.
A roadside diner at night with cars parked outside.
A long bar with a backlit wall of bottles.

Matrix light transport

A renderer that computes bounced light with matrix math on the GPU instead of random rays, so the image has no noise.

CUDA C++ / Python / Tensor coresOpen project
Eight renders of the same box room, each lit by a different colour of light.

Anti-unification compressor

A compressor that finds the repeated templates in a file and stores only the parts that change. Tested on 1 GB of Wikipedia.

AlphaFold on flexible proteins

I compared AlphaFold's predictions with lab measurements for 140 flexible proteins. It gets the rigid sections right and misplaces them relative to each other.
