This function fills the output value of the desired point with the value of the point in the solid whose index is index. index can have a value of 0, 1, 2, or 3, depending on which point is desired (that is, 0 for the first point, 1 for the second point, etc.). If there are only three corners on the solid, then the points with indices 2 and 3 will have the same value. The returned point will be in WCS coordinates.
