A Skysphere is a sphere object that is large enough to encompass your world.

A typical peice of code would be



The general idea is that as your camera moves, so does the sphere, to give the impression that the sky never moves, only rotates as the camera rotates.

Yes, the camera is inside the sphere, so it is surrounded on every side by the sphere. The sphere is textured and then turned inside out so the texture is on the inside, i.e facing the camera simulating a sky all around you.

Whatever I did I didn't do it!
