		<description>This sounds like a great explanation for something that I&#039;ve been trying to figure out for a while, however, I have a question.

I understand a little bit about matrix math, but after carefully following your instructions to create the 4x4 matrix, I don&#039;t understand how to use that matrix to get the Euler rotations that the constrained object needs to assume in order to aim at the target.

Could you help me understand?

Thanks so much,
Kirk</description>
