Detailed Description

Stores the current view volume.

This element stores the current view volume.

Warning

Open Inventor does not guarantee that the view volume element corresponds to the current view and projection matrix elements used for rendering. A node could, for example, set the SoProjectionMatrixElement but not the SoViewVolumeElement. An example of this is the SoDepthOffset node. If you need these matrices, it is safer to access them through the SoViewingMatrixElement and SoProjectionMatrixElement. Cameras nodes do set the view volume and both matrix elements on a render traversal.
