dual marching cubes table
I've just finished building these tables for dual marching cubes (by Nielson). VerticesNumberTable contains the length of the array of vertices to create for each Voxel (1 to 4 internal vertices), while EdgesTable is used to assign every one of these vertices to the right edges of the voxel, in order to use them to calculate internal vertex position and normal. Edgetable works a little like triTable for original marching Cubes algorithm. Every set of edges is separated by the next set by a -1. The list is closed by -2, so this value can be used to break a cycle.
#region EdgesTable
public static int[,] EdgesTable = new int[256, 16]
