Sphere

Pretty much what you would except of a 3D sphere. When texturing the sphere, remember to consider the 'u extent' and 'v extent' These determine the way that the input texture maps over the sphere. One important use for this is to supply a curved backdrop to a camera. In the snippet below, play with the u and v extend knobs to see the effect they have on the texture.

Press 'Expand' and select and copy everything below this line, then paste into the Nuke node graph.
