Detailed Description

Stores a view volume subset.

This element stores a view volume subset. This element is used for "tiled" rendering, where we create a large image by rendering one tile (subimage) at a time. In this case we must "narrow" the view volume for each tile, without modifying the camera nodes in the scene graph. SoCamera::computeView uses this element to modify the view volume after other adjustments have been made. See also SoOffscreenRenderArea.
