Outlines of glucylinder?

OpenGL OpenGL: Advanced Coding

Is is possible to obtain the outlines of the polygons that define the cylinder called by glucylinder funcion?
The intention is to increase speed when someone rotates, pans or zooms the object.

Rendering the wireframe of an object might actually slow down the framerate depending upon what video card you have. The GeForce family of video cards are notorious for this. Anyway, to render the wireframe of a quadric, just call gluQuadricDrawStyle with GL_LINE as the second argument. Hope that helps.
