Sphere

Purpose:

This node is another of the eight shape Nodes. It provides you with a representation of a sphere. The node's default values create a sphere centered at the origin of (0,0,0) and having a radius of 1. This node, as with other shape nodes, is transformed by the current cumulative transformation and is drawn with the current material and texture.

Syntax

FILE FORMAT/DEFAULTS
Sphere {
	radius	1	# SFFloat
}

Explanation

This node doesn't have any faces or parts. The node therefore ignores material and normal bindings. Instead, Sphere uses the first material for the entire sphere. It also uses its own normals. When you apply a texture to the sphere, the texture will cover the entire surface. The texture will be wrapped counterclockwise from the back of the sphere and will therefore have a seam along the back on the yz-plane.

Example Use

The following code fragment is from LODtest.wrl.

Sphere { } # for [3, 5)
