Method Detail

geodesate

public static void geodesate(org.openmali.vecmath2.Vector3f a,
                             org.openmali.vecmath2.Vector3f b,
                             org.openmali.vecmath2.Vector3f c,
                             int N,
                             int offset,
                             org.openmali.vecmath2.Vector3f[] vertices)

This method can be used to geodesate a triangle. In mathspeak, project the nth-order tessellation onto the unit circle. In English, subdivide the triangle into N^2 smaller triangles of the same proportions, and then map all the new vertices to the unit circle. (This routine assumes a, b, and c are already unit vectors.)

Parameters:

a - First corner (should be a unit vector)

b - Second corner (should be a unit vector)

c - Third corner (should be a unit vector)

N - Number of splits in each edge

offset - Offset to base vertex index

vertices - Target vertex array
