sphere coordinates problem



Hi All,
I'm trying to produce a planetarium effect. ie. the eye point in the
centre of a sphere looking around at the interior. I want to be able to
place textures on the inside of the sphere based on azimuth and elevation.
What's the best way of doing this?.

Each texture would be defined positionally by the azimuth and elevation of
each corner. Is there an easy way of doing this or do I have to calculate
the 3d position of all of the vertices and texture them appropriately in a
manual way?.

Any pointers would be appreciated.

Ta,
Dave
