If a point (x, y, z) is rotated through angle θ about x – axis to a new point (x’, y’, z’) then the new point is calculated as y’ = y cosθ – z sinθ z’ = y sinθ + z cosθ x’ = x About y – axis z’ = z cosθ – x sinθ x’ = z sinθ + x cosθ y’ = y About z – axis x’ = x cosθ – y sinθ y’ = x sinθ + y cosθ z’ = z Scaling Scaling with respect a selected fixed position (xf, yf, zf) can be represented with the following transformation sequence: 1. Translate the fixed point to the origin 2. Scale the object relative to the coordinate origin 3. Translate the fixed point back to its original position The equations for this sequence of transformation is (where s is scaling factor) x’ = x * s + (1 – s) * xf y’ = y *s + (1 – s) * yf z’ = z * s + (1 – s) * zf Source Code.
