SoTransformSeparator – group node that saves and restores transformation state
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.
