SurfaceProjectWithGuessPoint Method

Project a 3D point orthogonally onto a surface (to find the nearest point). This method is meant to be used when a good approximate solution for the projection is available. Throws InvalidOperationException if the projection fails.

        uv : UV byref * 
        distance : float byref -> unit

Parameters

point XYZ: The point to project.
guessUV UV: The calculation will look for a project near the provided UV.
uv UV: The surface coordinates of the projected point.
distance Double: Holds the distance from input point to its projection.

Exceptions

Exception	Condition
ArgumentNullException	A non-optional argument was null
InvalidOperationException	The projection failed.
