How to texture a cylinder map in OpenGL?

Question

I know how to make ATVs, and it was pretty intuitive with the coordinates of the u, v texture, but it's hard for me to figure it out. Any help is appreciated.

Answer 1

Try to think about the parametric representation of the cylinder.

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

u and v are exactly the values ​​that you used as texture coordinates.
