Hi, I’m Addy! I’m interested in physics, rendering, and astronomy.
I’m a beginner at computer graphics and still learning from this great community.
Last year I wrote my first pathtraced renderer for iOS and I’m now learning FEM for 3d fluid simulation.

First test with ReSTIR, just for direct lighting for now. Figuring out the weights was a bit finicky, ngl. This scene is a bit too easy since all light sources are in the same spot, gonna try placing a bunch of light sources tomorrow.

Trying to implement (incorrect, hacky) reservoir merging and visualizing the reservoir contents, look way more modern-arty than it should

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.

Collaborated with Milkdrop to make a pack of 800 audio-reactive shaders.
Designed for VJs and visual artists. Anybody can use them with the open-source XorPlayer and Spout.
They work without audio too, great as moving backgrounds! Download:

Have fun!

signs of life on my attempt at shooting rays from a light source to eventually hit a film plane... it's spectral but the only materials so far are a perfectly mirrored mesh with slightly grey albedo, laid out in blender... need to add in refraction with ior dependence, and this will be very cool
