A browser reconstruction of the three original RealMatter demos: Soft Cows, Fracturing Zombies (Zombiechinko), and First Person.
Original RealMatter demo and FastLSM work: Alec Rivers. Original artwork: Wolfire Games. Recovered artwork is hosted with permission from Wolfire. This site is a modern reconstruction, with some extended interactions, rather than the original executable.
The browser version uses Three.js and a standalone FastLSM WebAssembly solver. It also includes Box3D for optional physics experiments.
