Detailed Description

Representation of a triangulated MarchingCubessurface in a volume defined by eight voxels.

If the MarchingCubessurface crosses any of x,y or z axes within the volume, a coordinate of that intersectionpoint is created in a coordinate list. Those positions are used by the triangles in this and neighboring volumes.

Each of the voxels are on either side of the threshold. Since there are eight voxels, 256 different configurations are possible.

Depending on the configuration of the voxels, one of 256 models are chosen, and some of those models have multiple submodels.

Each model/submodel corresponds to static configuration of triangles. The trianlges are drawn between this volume's coordinates, and the neighbor volume's coordinates.
