OpenGL - texture mapping and glutSolidSphere

I have this image of earth surface, and I want to map it to a glutSolidSphere. When I use

Code:

---

glTexGeni(GL_S,GL_TEXTURE_GEN_MODE,GL_SPHERE_MAP);

---

I get strange results.

My texture is fully visible from one side of the sphere, and when I turn, the scene, the texture does not turn with the sphere. It's like I'm always seeing the same side of the sphere. I don't see how to map the image all around the sphere.

my image file and the results are visible at my website

I have never been able to get glutSphere to work properly with textures. I suggest trying a gluSphere (it's the only one I have been able to properly wrap a texture around).

If I can, I will send you a little program that demonstrates the earth and moon in orbit around each other (also does some lighting effects), which uses a textured gluSphere (so you can see the actual implementation details).

Otherwise good luck (sphere texturing is one of the more painful things you can do, even if you aren't doing it manually).

I would really like that source of yours :P
