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.

SOA Cloth Simulation with 256-bit Intel® Advanced Vector Extensions (Intel® AVX)

This white paper describes a code sample that uses Intel® AVX for computing mesh-based cloth simulation. A structure of arrays (SOA) implementation is used to maximize data parallelism enabling usage of 256-bit (8 float) SIMD processing. Code is provided.

Embree: Photo-Realistic Ray Tracing Kernels

Photo-realistic rendering requires accurate simulation of light propagation according to physics laws. The best known way to solve this problem is Monte Carlo ray tracing. We describe a state-of-the-art photo-realistic Monte Carlo rendering engine.

Fast CPU DXT Compression

DXT compression is a lossy texture compression algorithm that can reduce texture storage requirements and decrease texture bandwidth. DXT decompression is typically hardware accelerated, which makes it very fast and efficient.

Software Occlusion Culling

This article details an algorithm and associated sample code for software occlusion culling which is available for download. The technique divides scene objects into occluders and occludees and culls occludees based on a depth comparison with the occluders that are software rasterized to the depth buffer. The sample code uses frustum culling and is optimized with Streaming SIMD Extensions (SSE)...
