voxj-codec

Encodes and decodes Voxel Json .voxj / .voxjz documents.

encode_voxj_file / encode_voxj_file_smallest / decode_voxj_file convert a whole document between the codec form (voxj::VoxjCodecFile, objects holding raw positions/samples) and the serde form (voxj::VoxjSerdeFile, objects holding encoded blocks): encode_voxj_file applies fixed block encodings, encode_voxj_file_smallest tries every encoding pairing and keeps the smallest deflated, and decode_voxj_file is the inverse. from_voxj_file_bytes / to_voxj_file_bytes parse and serialize a voxj::VoxjSerdeFile to and from the uncompressed .voxj JSON form; from_voxjz_file_bytes / to_voxjz_file_bytes handle the zip-packaged .voxjz form, and from_voxj_or_voxjz_file_bytes accepts either, detecting the form by its leading bytes.

The per-object building blocks underneath: encode_voxj_object / encode_voxj_object_smallest / decode_voxj_object convert a single object between raw position and sample encodings, and voxj_palette_cell_counts computes the cell count of each palette an object's palette_refs name (the widths packed-base64 needs). See the voxj crate for the format specification.
