Real-Time Occlusion Culling with a Lazy Occlusion Grid
We present a new conservative image-based occlusion culling method to increase the speed of hardware accelerated rendering of very complex general scenes which may consist of mill...

Two Methods for Fast Ray-Cast Ambient Occlusion
Ambient occlusion has proven to be a useful tool for producing realistic images, both in offline rendering and interactive applications. In production rendering, ambient occlusion...

Hardware-accelerated ambient occlusion computation
In this paper, we present a novel, hardwareaccelerated approach to compute the visibility between surface points and directional light sources. Thus, our method provides a first-o...

An Information-Theoretic Ambient Occlusion
Ambient occlusion is a powerful technique that mimics indirect global illumination at a fraction of the cost. In this paper, we introduce a new ambient occlusion technique based o...

Fast Occlusion Sweeping
While realistic illumination significantly improves the visual quality and perception of rendered images, it is often very expensive to compute. In this paper, we propose a new al...
