Most games render clouds with planar cloud textures mapping to the sky dome, which isn't visually convincing when approaching or passing through clouds. For a realistic experience in flying games, we describe a technique for dynamic volumetric clouds.

This demo showcases an extension to Z-partitioning (cascaded shadow maps) called Sample Distribution Shadow Maps (SDSMs). SDSMs optimize the placement and size of a fixed number of Z-partitions by analyzing the shadow sample distribution required by the current frame. They build on the advantages of current state of the art techniques, including predictable performance and constant memory usage,...
We introduce adaptive volumetric shadow maps (AVSM), a real-time shadow algorithm that supports high-quality shadowing from dynamic volumetric media such as hair and smoke. The key contribution of AVSM is the introduction of a streaming simplification algorithm that generates an accurate volumetric light attenuation function using a small fixed memory footprint. This compression strategy leads to...
This sample demonstrates a number of deferred rendering techniques including conventional deferred shading, deferred lighting and tile-based deferred shading. Tile-based deferred shading is implemented in DirectX 11 Compute Shader and achieves high performance even with many lights by amortizing the light culling overhead over screen tiles as well as grouping lights to avoid wasting memory...
