evaluator

[Zak]

Is there a way to extract the co-ordinates of points on a b-spline or surface calculated by an evaluator and save it to a file?

Hi !

No, OpenGL has no support for this, you have to use an external spline library of some form.

You can also look at the OpenGL spec to get the formulas used so that you can calculate it yourself.

Thanks,

Thanks,

I am already using formulas from “The NURBS Book”. It works OK. But I was looking for an easy way.
