Detailed Description

This node represents a sphere. By default, the sphere is centered at the origin and has a radius of 1. The sphere is transformed by the current cumulative transformation and is drawn with the current lighting model, drawing style, material, and geometric complexity.

A sphere does not have faces or parts. Therefore, the sphere ignores material and normal bindings, using the first material for the entire sphere and using its own normals. 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 on the yz-plane.

Action Behavior

SoGLRenderAction
Draws sphere based on the current coordinates, materials, drawing style, and so on.

SoRayPickAction
Intersects the ray with the sphere. No details are created for intersections.

SoGetBoundingBoxAction
Computes the bounding box that encloses the sphere.

SoCallbackAction
If any triangle callbacks are registered with the action, they will be invoked for each successive triangle that approximates the sphere.
