An ASCII and halftone post-processing effect for three.js built on pmndrs/postprocessing. The scene is sampled on a cell grid, each cell's luminance picks a glyph from a runtime-generated glyph atlas, a Sobel pass swaps in directional edge glyphs along contours, per-cell temporal memory keeps characters from flickering between frames, and an SDF field morphs the glyph grid into arbitrary shapes.
