Remarks

This element stores the rectangular area within the current viewport region that needs to be updated when rendering. It can be used for partial rendering updates when applications know that only a portion of the objects need to be rerendered. Cameras can use the info in this element to set up a view volume against which culling can be performed. This element also sets up the GL scissor box to limit drawing.

The update area is specified in normalized viewport coordinates, where (0,0) is the lower left corner of the viewport and (1,1) is the upper right corner. The area is given as an origin and a size.
