Voxels

A voxel is a sub-volume box with constant scalar/vector value. The object in voxel representation is split into many small sub-volumes (voxels) and its properties are distributed through voxels.

Voxels are used for analysis and visualization of 3D-dimensional distribution of data. Medicine (mainly, tomography), computational physics (hydrodynamics, aerodynamics, nuclear physics) and many other industries use voxels for 3D data visualization and analysis of physical processes.

Open CASCADE provides several basic data containers for voxels with fast access to the data and optimal allocation of data in memory. Also, a special visualization toolkit allows visualizing voxels as colored or black/white points and cubes, displaying only the voxels visible from the user's point of view.
