heerich.js

heerich.js is a zero-dependency JavaScript library that converts 3D voxel compositions into resolution-independent SVG graphics. It supports multiple camera projections (oblique, perspective, orthographic, isometric), boolean operations for adding and subtracting geometry, and per-face styling. The output renders natively in the DOM as semantic markup, enabling CSS manipulation and infinite scaling without pixel degradation.

Designed for developers building geometric visualizations, the engine draws inspiration from sculptor Erwin Heerich's cardboard works. According to the repository, the project was built with Claude Code. Users can construct scenes by stacking voxels, applying transformations, and querying geometry programmatically before exporting to SVG.
