Screen Space Ambient Occlusion Ambient occlusion is a lighting model that approximates the amount of light reaching a point on a diffuse surface based on its directly visible occluders.

The Knight model used in this project has kindly been provided by animedia PM at Turbo Squid and can be found here. Percentage Closer Soft Shadows Percentage Closer Soft Shadows (PCSS) is a shadow mapping technique that renders realistic soft shadows with varying penumbra that harden on contact. This is accomplished with sub-sample stencil routing, and therefore requires Direct3D 10's ability to read from an MSAA render target. The results are similiar to depth peeling (an implementation is included) but since multiple layers are captured at once it is much faster. Stencil Routed K-Buffer This sample illustrates a method for capturing 8 layers of fragments with a single geometry pass. The algorithm by Loop et al in Approximating Subdivision Surfaces with Gregory Patches for Hardware TessellationĪnd the algorithm by Myles et al in Fast Parallel Construction of Smooth Surfaces from Meshes with Tri/Quad/Pent Facets. Control points of the approximation mesh are precomputed using the algorithm by Loop and Schaefer in Approximating Catmull-Clark Subdivision Surfaces with Bicubic Patches,

The example uses tessellation to render a displaced subdivision surface rendered with a polynomial approximation to the Catmull Clark surface. Adaptive tessellation is implemented as described by Dyken et al in Semi-uniform Adaptive Patch Tessellation Instanced Tessellation This example shows how to simulate tessellation using instancing.
