Hi,

Think I'm going to get out of my depth here but...

Given a Bezier spline (that I've defined so I know the end and control points) how can I determine the slope of the tangent at a particular point on the spline?

Actually I *think* I can do that - but it's over simpifying the requirement. What I really need, given a secant of the spline from a known start point and of known length, is to determine its end point (or slope)

I could use a cardinal spline instead of a Bezier if it was easier to obtain the result but that looks more difficult to me...

Regards,
Viv
