multiplyInversePoint3dArray Method

Multiply each point in the array by the inverse of this Transform.

• For a transform T = [M o] the inverse transform T' = [M' -M'o] exists if and only if M has an inverse M'. Indeed, for any point p, we have T'Tp = T'(Mp + o) = M'(Mp + o) - M'o = M'Mp + M'o - M'o = p.
• If result is given, resize it to match the input points array and update it with original points p[].
• If result is not given, return a new array.
• Returns undefined if the matrix part if this Transform is singular.
