This library contains voxel storage modification code, meant to be reasonably performant and flexible. It's generic over the voxel type, with specific voxel implementations in src/impls.

It is by no means complete! Changes and additions are heartily encouraged, although some things (e.g. mesh extraction) might go better in separate libraries on top of this one.

Sparse Voxel Octree

The tree module defines a sparse voxel octree (SVO) data structure. Every branch point in the tree can optionally contain a single voxel to represent that entire section, so the same space can be stored at multiple levels of details.

Fields, Mosaics & Brushes

The field modules defines a field trait to define a density and normal for every point in space. This is used to represent volumetric data. The mosaic module extends fields with materials, such that any point in space can correspond to a material, or to nothing. Mosaics are the basis for voxel brushes, which can be used to edit the SVO. Brushes provide the bounds of the brush, as well as a mosaic; everywhere the mosaic defines a material, the corresponding voxel is overwritten.

A few basic fields and mosaics (such as spheres) are provided, and some "higher-order" types are provided to transform or combine simpler ones.
