      • closestPlanePointIndex

        private float closestPlanePointIndex​(WildMagic.LibGraphics.Collision.PickRecord kPickPoint)

Because the mesh is closed, even for the plane, the edge triangles wrap around the back of the mesh, and are co-planar with the forward-facing triangles (the ones that display the data) -- when picking is done, the pickClosest sometimes returns the back-facing triangle. This function returns the correct, visible triangle for the plane:

        Returns:
        the minimum distance to the plane.
