The Intel real-time path tracer is up on Github now: https://github.com/intel/RealTimePathTracingResearchFramework . It began as a fork of https://github.com/Twinklebear/ChameleonRT , and has gone way beyond it to add tons of awesome capabilities for real-time path tracing research in #Vulkan ! It's exciting to see it out publicly now, so definitely check it out!
