Sphere { radius r }Explanation :
The Sphere node specifies a sphere centered at (0, 0, 0) in the local coordinate system. The radius field specifies the radius of the sphere and must be >= 0.0.
When a texture is applied to a sphere, the texture covers the entire surface, wrapping counterclockwise from the back of the sphere. The texture has a seam at the back where the YZ plane intersects the sphere. TextureTransform affects the texture coordinates of the Sphere.
The Sphere geometry is considered to be solid and thus requires outside faces only. When viewed from the inside the results are undefined.
