- Hi,
- Could anyone out there help me determine the best fitting
- Bezier Curve for a Circular arc.
-
- Given a Circular Arc of:
- radius, R
- begin point, X0
- end point, X1
- where X0 and X1 are in Euclidean 3 space
-
- Find the Bezier Curve Control Points of best fit
- (i.e. Control Points are vectors of length 3)
- Presently, the Bezier Curve should be of order 3 (i.e. cubic),
- but, I would also like the general order n form if possible.
- NOTE:
- The best fit Bezier Curve I need is standard Bezier,
- not Rational Bezier.
-
-
- Formulae would help, some insight, or some good text books.
-
- This problem is one of many for which I am writing code ... to
- be implemented in a surfacing package. So any good (easy to understand)
- text references would be appreciated. Lord knows, I'll be
- working on these problems for a while.
-
-
- Thanx in advance,
- Mark Turella
