BIOMASS

BIOMASS is tower defense with a ridiculous crowd of zombies. The crowd runs in WebGPU compute: steering, contact, damage and death all happen on the GPU.

The interesting bit is what happens when they pile into each other. They’re using a position-based contact solver, so the horde presses together like a liquid. A zombie stuck at the back can’t just keep walking through the ones in front of it. Change the map and the flow field gets rebuilt, then the crowd finds its way around the new shape.

It’s built with Three.js and WebGPU, inspired by Sir, We Have an Orc Problem from Mumpitz Games.
