1. A computer implemented method of rendering a 3-D voxel-based object from a voxel chain representation of the object stored in a computer memory the method comprising:

  • a) rotating a set of incremental vectors to obtain a set of rotated incremental vectors;

    b) saving the set of rotated incremental vectors in a lookup table in the computer memory;

    c) calculating coordinates in a camera coordinate system of a first voxel in the voxel chain representation;

    d) calculating coordinates in a camera coordinate system of a second voxel of the voxel chain through the use of one of the rotated incremental vectors; and

    e) displaying a rendered image of the 3-D voxel-based object from the calculated coordinates.
