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 computes Tp = M*p + o*w and returns the Point4d formed by Tp in the first three coordinates, and w in the fourth.
  • Logically, this is multiplication by the 4x4 matrix formed from the 3x4 instance augmented with fourth row 0001.
