Method Detail

### computePointAt

    public static Vec3D computePointAt(float u,
                                       float v,
                                       Vec3D[][] points)

  Computes a single point on the bezier surface given by the 2d array of control points. The desired point's coordinates have to be specified in UV space (range 0.0 .. 1.0). The implementation does not check or enforce the correct range of these coords and will not return valid points if the range is exceeded.

  Parameters:
    `u` - positive normalized U coordinate on the bezier surface
    `v` - positive normalized V coordinate on the bezier surface
    `points` - 4x4 array defining the patch's control points
  Returns:
    point on surface

                           int y,
                           Vec3D p)
