1. A method for determining the bounding voxelization of a triangle represented in a three dimensional space to be represented in a grid, said method comprising the steps of: dividing a triangle into a plurality of polygons, each being an intersected slice of a grid; rasterizing each polygon individually to determine an intersection of each edge with voxels on the defined slice for a given axis position; marking strips of said voxels iteratively using minimum and maximum voxel positions along a secondary axis for a tertiary axis.
