CreateSphere:Int32 segments:Int32=8, parent:Int32=0

Parameter	Mode	Type	Default	Description
segments	In	Int32	8	Detail of the sphere, 2 to 100. Defaults to 8.
parent	In	Int32	0	Entity the sphere follows, or 0 for none. Defaults to 0.

Returns: The handle of the new sphere.

Description

Creates a sphere with a radius of 1 around the origin. segments sets how round it looks. A sphere has 2 * segments * (segments - 1) * 2 triangles, so 8 gives 224 and 16 gives 960, and 4 * segments + (segments - 1) * (2 * segments + 1) vertices (151 for 8): each pole has a vertex for every segment, and the seam of a ring is repeated, as in the original. Use the smallest number that still looks smooth at the distance the sphere is seen from. Valid values are 2 to 100.
