PUNCTUM

Punctum — the accident that pierces the smooth surface. Not pixel-level glitch effects but corruption of the signed distance field itself. The geometry doesn't break visually — its mathematics become impossible. Inside becomes outside. Distance lies. Space tears.

WebGPU compute shaders evaluate and corrupt the SDF in parallel. Each texel holds a distance value that has been destabilized — entropy accumulation, field fracture, sign inversion, temporal echo. The contour lines expose the computational substrate: you see the math breaking.
