vox
What is a .vox file?
application/x-vox
VOX is MagicaVoxel's chunked binary voxel-scene format. A VOX header and version are followed by a MAIN container whose SIZE, XYZI, RGBA, palette, transform, group, and shape chunks describe voxel models and optional scene hierarchy using little-endian integers.
How to use a .vox file
Use an example .vox file to test chunk traversal, palette indexing, voxel-coordinate bounds, multi-model scene links, unknown-chunk skipping, and comparison of the occupied voxel set after conversion.
