This screenshot was produced by some proof-of-concept visibility
technology I've been working on recently.
The upper-left shows a bird's-eye view of the visible polygons as they
relate to the viewer.
The upper-right pane shows the rendered image of the visible polygons
The lower-left pane shows the scene with no visibility solution applied.
The lower-right pane shows the non-conservative visibility solution.
This image is one frame from an animation of a very dynamic scene. You can
download the animation and/or find more information on our website at:
