Masking a textured sphere question
Author
Hi All,
I'm masking using the following code:
My texture is covering half of the sphere and the other half is invisible. But when I rotate the sphere and I look upon the the texture from behind I connot see the theture. It is only visible from the front of the sphere.
How can I make my half-a-sphere viewable from each side (front and back)?

Thanks for the reply Jerax!
But it did not work. I was still not able to see through the 'invisible' masked part of the texture and see the back of the texture on the sphere.
-----
BTW I have disabled the depth buffer, drawn the sphere and enabled the depth buffer again. This had the wanted result of viewing the texture from all angles. But when I draw an object above it the object becomes transparent because of the disabled depth buffer and blends with the sphere texture.
