public class SoLogicalViewportElement extends SoElement
Stores the logical viewport region. This element stores the logical viewport region, which indicates to the camera(s) the whole size of the window which is being rendered into. This information is needed when the viewport region has been split, so that the camera doesn't adjust its parameters on only a part of the whole window.LogicalViewportElement is used for "tiled" rendering
in this case it contains the size (and aspect ratio) of the complete large image, while ViewportRegionElement contains the size of the tile (subimage) we are currently rendering. SoCamera.computeView uses the logical viewport's aspect ratio for ADJUST_CAMERA mode, so we render all the tiles with the same adjustment (but only if the LogicalViewportElement was actually set during traversal see SoOffscreenRenderArea
).- See Also:
