The interaction of light and matter in the world surrounding us is of striking complexity and
beauty. Since the very beginning of computer graphics, adequate modelling of these …

Thoroughly revised, this third edition focuses on modern techniques used to generate
synthetic three-dimensional images in a fraction of a second. With the advent of …

Physically plausible illumination at real-time framerates is often achieved using
approximations. One popular example is ambient occlusion (AO), for which very simple and …

We introduce a visually pleasant ambient occlusion approximation running on real-time
graphics hardware. Our method is a multi-pass algorithm that separates the ambient …

High quality image synthesis is a long-standing goal in computer graphics. Complex
lighting, reflection, shadow and global illumination effects can be rendered with modern …

Ambient occlusion (abbr. AO) plays an important role in realistic rendering applications
because AO produces more realistic ambient lighting, which is achieved by calculating the …

This survey deals with obscurances and ambient occlusion. These are relatively cheap
techniques that simulate diffuse indirect illumination in a way that looks realistic, though they …

Obscurance and Ambient Occlusion (AO) are popular techniques in both film and games
that model how ambient light is shadowed. While it is largely a solved problem for static …

Ambient occlusion captures a subset of global illumination effects, by computing for each
point of the surface the amount of incoming light from all directions and considering potential …

This new algorithm, based on GPUs, can compute ambient occlusion to inexpensively
approximate global-illumination effects in real-time systems and games. The first step in …
