volume pixel (Voxel)

While a pixel is two-dimensional, a voxel adds the third dimension, spatial depth

. The abbreviation voxel is derived from the term volume pixel. A voxel is thus described by three coordinates: Length, Width, Depth. For true 3D representations, the voxels must undergo a transformation in which they receive different opacities. This is the prerequisite to be able to examine 3D bodies also with regard to the inner structure. Corresponding images

areknown in medicine from computer and magnetic resonance tomography.

Classical 3D representations are easier to process due to the voxels and can be viewed from all sides. Voxelization allows the user to add depth to two-dimensional graphics and images.
