Abstract
Hardware occlusion queries make it possible for an application to ask the 3D API whether or not any pixels would be drawn if a particular object was rendered. With this feature, applications can check to see whether or not the bounding boxes of complex objects are visible; if the bounds are occluded, the application
can skip drawing those objects. In this chapter, we present a simple and powerful algorithm to solve the problem of latency and CPU/GPU stall typically associated with a naive usage of hardware occlusion queries.
