Direct Known Subclasses:

SoGLClipPlaneElement

public class SoClipPlaneElement
extends SoAccumulatedElement

Stores the current set of clipping planes, specified as SbPlanes. This element stores the current set of clipping planes, specified as SbPlanes.

When a plane is added, this element gets the current model matrix from the state and stores it in the instance. This allows the get() method to return the clip plane in object space (the plane as originally defined) or world space (after being transformed by the model matrix).
