A voxel is an element of a 3D grid. Depending on the representation, it can store occupancy, density, distance, color, learned features, or other attributes.

- A polygon
Dense and sparse grids
Dense grids allocate every cell in a volume. Sparse structures store active regions, which is important because most of the volume around a surface is empty.
Interpret cubic resolution carefully
A label such as 1024³ describes a three-dimensional resolution setting. It does not mean the exported mesh contains that many vertices or the texture is 1024 pixels wide.
