How do I texture map a cylinder in OpenGL?

Question

I know how to do quads and that was pretty intuitive with the u,v texture coordinates but I'm having a hard time figuring this out. Any help is appreciated.

Answer 1

Try to think about the parametric representation of a cylinder

cylinder(u, v):
    x = r * cos(u * 2*pi)
    y = r * sin(u * 2*pi)
    z = v

u and v are exactly those values you'd use as texture coordinates.
