I would like to display a cylinder in openGL. In order to do that, I would like to use the b-spline. 16 Control points(4 in U and 4 in V). The shape will be a square in U and a line in V. My first question is the following:
How can I display the "cube" created by the 16 control points using GL_LINE_STRIP?
I am also looking for a tutorial about B-spline and openGL.
Thank you for any help you can give!!!
