AyaRay

Last update: 2020/4/16

AyaRay is a physically based Windows-platform renderer. AyaRay is written in modern C++ and integrates multi-threading and SIMD at the bottom to optimize high-performance computing. It includes many state of the art algorithms published in recent years in light transport simulation. The ultimate goal of AyaRay is to have a complete offline rendering procedure, and provide the corresponding workflow for the artist.

Welcome to use any part of the code or the application in any place, but it should be warned that for now the code is just a demo. And it has no enough ability in any commercial occasions. If you have any issue, please post to the issue page and I will reply as early as I can.

Demos

Build

Because the project is still building and need fast iteration, so it has not provide project file yet, you can include all files to build the current version.

Compile switch

• AYA_DEBUG debug option (off by default)
• AYA_USE_SIMD Use SIMD / SEE instructions in the math library (on by default)
• AYA_SAMPLED_SPECTRUM Use Sampled Spectrum replace RGB Spectrum (off by default)
• AYA_USE_EMBREE Replace default BVH to Intel® Embree BVH (default ver.2)
• AYA_USE_EMBREE_STATIC_LIB Make Embree provided as static lib (on by default)
