Embree:照片级光线追踪内核

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.

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.
