Detailed Description

The Sphere node specifies a sphere centred at (0, 0, 0) in the local coordinate system.

The radius field specifies the radius of the sphere and shall be greater than zero. Figure 13.8 depicts the fields of the Sphere node.

When a texture is applied to a sphere, the texture covers the entire surface, wrapping counterclockwise from the back of the sphere (i.e., longitudinal arc intersecting the -Z-axis) when viewed from the top of the sphere. The texture has a seam at the back where the X=0 plane intersects the sphere and Z values are negative.

The solid field determines whether the sphere is visible when viewed from the inside. If solid is false both sides of the sphere will be rendered.
