public class SharedEdgeVertex

extends SharedVertex

Description: The purpose of the SharedEdgeVertex object is to avoid paging. When a finer resolution octree node discovers that it has a vertex that is either on the face or the edge of a coarser resolution (adjacent) neighboring node, the finer resolution node instantiates a SharedVertex object and adds it to the coarser resolution neighbor's sharedVertexList. Then when Marching Cubes is done, a second pass is made through all of the coarser resolution nodes with a non-empty sharedVertexList, and then their triangles are updated. The SharedVertex object is used to remember state information such as:

1. The TriangleVertex that is shared
2. the edge of the coarser cube the SharedVertex may be on
3. the octant that the finer resolution node responsible for generating the sharedVertex is in
