Slime Mold Simulation Shaders

Thousands of agents are being simulated on your GPU in realtime, rendered in browser.

Based on a variety of papers detailing methods for slime mold simulation, Sean has created a few of his own artistic implementations of this unique technique. Porting the shaders to web proved to be non-trivial; the shaders ended up being completely rewritten from the ground up. The greatest challenge was overcoming WebGL's lack of Read/Write shader buffers, an integral feature utilized in multiple places in the original shader code. Information on how this was accomplished is available on Sean's Github devlog.

Eyeball Audio Visualizer

A realtime audio visualizer which works with any recording device or song. This was made in Unity's HDRP and uses an implementation of the slime shader as well as a few other custom shaders. The agents' logic had to be reigned in to create an eyeball effect and 'burst' at moments of musical intensity.

Edge Highlight Shader

This is the first in a suite of shaders intended to easily and algorithmically paint models in a miniature-painting style. A highlight map is baked on the cpu based on relative angle between vertices and relative distance between vertices.

This is essentially a way to bake a crease map, though is highly customizable and built in Unity with the intention of mimicking common miniature painting techniques such as edge highlighting and washes.

Photography

Sean enjoys exploring the natural world via car, plane, train, backpacking, and camping. In his adventures, he likes to capture beauty via photography and has developed a portfolio over many years.
