turing-sphere

Reaction-diffusion on the sphere, solved live with spherical harmonics: implicit spectral diffusion + explicit reaction (IMEX Euler), transforms on WebGPU via shtns-webgpu. The solver itself is the MATLAB below — numbl parses and lowers it in your browser, and each line becomes a WebGPU compute kernel. Edit it and the pattern changes. Drag to rotate.
