Detailed Description
A regular subdivision of an AABB3D into a cell count per axis.
Pairs the continuous extent AABB3D describes with the discrete resolution a sampled field, a simulation grid, or an extraction pass imposes on it. Everything else is derived: cell size, cell centre, corner position, linear index.
Indexing is x-major, y next, z outermost, matching the layout volume_common.glsl assumes and the order VolumeGridBuffer allocates in. A different traversal order is a different type, not a flag on this one.
Cell-centred and corner-sampled are both expressed here rather than chosen at construction: marching cubes reads corners of the same lattice whose centres a simulation writes, and forcing that choice into the type would require two lattices where one describes the geometry.
