com.openinventor.inventor.elements.SoModifyViewVolumeElement

public class SoModifyViewVolumeElement
extends SoElement

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.
