Map a texture on the inner side of the sphere

does anyone know how to map a texture on the inner side of a sphere?

Just map a texture to a sphere normally (try gluSphere) and use gluLookAt to put your eye inside the sphere looking out.

it’s not working, when i’m inside the sphere it disappears.

What disappears? The sphere? Is backside culling enabled?

The sphere disappears,i used this glEnable(GL_CULL_FACE);maybe this is the problem

it’s working now i used glEnable(GL_BACK); that was the problem thanks
