I''m not sure what you mean. Do you want to find the angle between two vectors? Use the dot product for that.

no no no, I''ve reduced the problem down to I have 2 angles now between +180 and -180 off the x axis and I want to know whether they are within X degrees of each other.

Uh...

|angle1 - angle2| < x

?

Cédric

|angle1 - angle2| < x OR 360 - |angle1 - angle2| < x
