DESCRIPTION

This group node is similar to the SoSeparator node in that it saves state before traversing its children and restores it afterwards. However, it saves only the current transformation; all other state is left as is. This node can be useful for positioning a camera, since the transformations to the camera will not affect the rest of the scene, even through the camera will view the scene. Similarly, this node can be used to isolate transformations to light sources or other objects.

METHODS

       
                    
                     SoTransformSeparator()
Creates a transform separator node with default settings.

       
                    
                     SoTransformSeparator(int nChildren)
Constructor that takes approximate number of children.

    static SoType    
                    
static SoType        getClassTypeId()
Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoGetMatrixAction, SoRayPickAction
Saves the current transformation state, traverses all children, and restores the previous transformation state.

FILE FORMAT/DEFAULTS

TransformSeparator {
}
