Dynamic Volumetric Cloud Rendering for Games on Multi-Core Platforms

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.

IIR Gaussian Blur Filter Implementation using Intel® Advanced Vector Extensions

This white paper proposes an implementation for the Infinite Impulse Response (IIR) Gaussian blur filter using Intel® Advanced Vector Extensions (Intel® AVX) instructions. For a 2048x2048 image size, the AVX implementation is ~2X faster than the SSE code.

3D Vector Normalization Using 256-Bit Intel® Advanced Vector Extensions (Intel® AVX)

This article shows how to use 256-bit Intel® Advanced Vector Extensions (Intel® AVX) to normalize an array of 3D vectors. We describe a shuffle approach to convert between AOS & SOA on-the-fly in order to make data ready for up to 8-wide SIMD processing.
