openGL and spline rendering

can you render, transform and store spline objects using openGL ?

please help !

What do you mean from the spline objects?
I OpenGL you can draw many primitives, such a TRIANGLES, QUADS, POLYGONS, etc.
See glBegin/glEnd specification:


glu has support for splines, but only for rendering them, you can transform the result of course but there is no spline manipulation functions in glu you would have to use some other library for that (irit for example).
