Don't know if this Q belongs here or in Advanced.

I need to know how to get actuall coordinates from a spline so I can make a camera (or an object) follow a spline path...

I am using the 1D spline example in the Red Book as my spline, (glEvalCoord()) and I just can't figure out how to get the coordinates out so I can put them into my gluLookAt function...

any help?

Thanks,

Hm, if you have the spline equation there is nothing stoping you to generate any point on it, you just have to know how http://www.opengl.org/discussion_boards/ubb/biggrin.gif

Because I think this would be to much for this forum, just grab a good math book that covers bezier curves and surfaces.
