multiplyXYZW Method
Transform the homogeneous point. Return as a new Point4d, or in the pre-allocated result (if result is given).
- If p = (x,y,z)then this method computesTp = M*p + o*wand returns thePoint4dformed byTpin the first three coordinates, andwin the fourth.
- Logically, this is multiplication by the 4x4 matrix formed from the 3x4 instance augmented with fourth row 0001.
