Hi, > Or do I have to add my own code to answer queries like is point (x,y) close enough to that bezier curve to register a hit, on a mouse click?
CD does not have functions like that, it is a simple graphics library. Such questions don't usually be solved by graphics libraries. Foley is a great reference, Graphics Gems is another. I would search for algorithms and implement myself...
