Sphere {
field SFFloat radius 1 # (0,∞)

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 6.15 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. TextureTransform affects the texture coordinates of the Sphere.

The Sphere node's geometry requires outside faces only. When viewed from the inside the results are undefined.

cover Covers VRML 2 (but not the upcoming X3D standard). A good introduction to all VRML2 node types and how to build them.

cover This book introduces 3D concepts, VRML, Java3D, MPEG4/BIFS, and X3D. It is a very good introduction to the theory, The writers have an in depth knowledge due to their involvement in the standards making. This is a good book to help you choose which 3D open standards to use and to give you a good insight into these standards. It is probably not for those who want a basic introduction to 3D or for these who want a step-by-step programming in 3D book.
