A method to generate polygonal boundary representations
from voxel-based volume representations is presented.
As an auxiliary data structure, the algorithm makes
use of a face octree extracted
from the voxel-based volume representation.
The precision of the computed boundary is given by the
length of the main diagonal of the voxels in the initial
Experimental results that illustrate the method are
