Plane.DotNormal Method |
Language: |
Computes the dot product of a plane and a 3-D vector. The w parameter of the vector is assumed to be 0.

value that represents the dot product of the plane and the 3-D vector.
Given a plane (a, b, c, d) and a 3-D vector (x, y, z), this method's return value is a*x + b*y + c*z + d*0. The DotNormal method is useful for calculating the angle between the normal of the plane and another normal.
