How about creating 1 NSGradient instance for each color you want, then creating one bezier path for each line. The path would describe the outer edges of the pipe, then you'd *fill* it with the gradient at the desired angle, rather than stroking.
Thanks for your response. I'm nearly convinced to look into the gradients tomorrow, although I'm afraid it won't result in a better performance: Empty the path, calculate the angle, create the rect (with rounded edges), apply the gradient and fill the path ... vs. three move to / line to ... I'll see.
If you need better performance than that, you should seriously consider OpenGL. In fact, you should be kind to your users' batteries and processor loads (you *are* considering laptops, aren't you?) and consider OpenGL anyway. It'd make quick and light work of this by comparison ...
OpenGL to make some basic lines look somehow three-dimensional? Isn't that over-kill? Sorry for my ignorance, I haven't coded OpenGL, yet, and I am a bit reluctant to add it to my (already long) todo list for this project ... But it would be interesting ... I'll have to make up my mind :-)
