Re: angle calculation from three points

[Judd Storrs]

It sounds like you're on the right track (Reading between the lines it seems like you're doing something like a vector dot product and extracting the angle using an arccos). Nothing in your question really sounds wrong about your approach. Post some relevant code that doesn't work.

changes. I was trying to use the the formula for acos but I'm not getting
anywhere. Could anybody help me?
