dotProductStart3dEnd4d Method

Returns the dot product with vector (pointB - pointA * pointB.w)

• That is, pointA is weighted to weight of pointB.
• If pointB.w is zero, the homogeneous pointB is a simple vector
• If pointB.w is nonzero, the vector "from A to B" is not physical length.

dotProductStart3dEnd4d(pointA: Point3d, pointB: Point4d): number
