How do you texture map an object like glutSolidTorus()? glutSolidTeapot seems to automatically take on texture mapping without giving coordinates but none of the others do. I have an object made out of Torus'' and would like to texture map it with a bitmap. So far it only works on teapots

I''m not sure exactly what glut does, and doesn''t because I don''t use it myself... But OpenGL can automatically generate texture coordinates for you:

glTexGen(GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR);
glTexGen(GL_T, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR);
glEnable(GL_TEXTURE_GEN_S);
glEnable(GL_TEXTURE_GEN_T);

Add this to your code, and it will work...

The last parameter og glTexGen can also be GL_EYE_LINEAR or GL_SPHERE_MAP... Try them, and you''ll see some cool stuff!

Thanks, what header file do I need to include for this?

Man, I keep forgetting to log in...how do you stay logged in? Anywho, I figured it out. I guess it's supposed to be glTexGeni?
I put that in and it works...found it on a website. Thanks once again James! You're a life saver...or a sanity saver. Whichever goes first.

p.s. You're right about that last parameter...very cool effects.
