glyphcss

>Turn 3D models into ASCII art, rendered as text in a single<pre>. No WebGL. No <canvas> — inspect, hover, and click every cell.

>Load OBJ, glTF, GLB, STL, and MagicaVoxel VOX — with UV textures and material colors. Works with vanilla JS, React, and Vue, or straight in your terminal.

[ HOW IT WORKS ]

>glyphcss loads OBJ, glTF, GLB, STL, and VOX mesh files. Each scene renders into a single <pre>: the rasteriser projects every polygon, fills a cols × rows character grid, and writes one string to textContent per render. There are no per-polygon DOM nodes and no matrix3d.

>Interactivity is opt-in and sparse: drop a <GlyphHotspot>at any 3D anchor and glyphcss emits one absolutely-positioned<div> over the projected cell. Real DOM events, real :hover styles, real role="button"accessibility — without one DOM node per polygon.

[ HELLO WORLD ]

>glyphcss provides custom elements (<glyph-scene>, <glyph-mesh>), an imperative createGlyphScene API, and optional React / Vue bindings. Use whichever entry point fits your stack.
