Description

Hi, I was curious if there is any support for ray tracing. I am interested in prototyping raytracing applications on macOS with Metal 2 and then scaling them up for production on Nvidia's RTX GPUs.

Contributor guide

Research direction
Investigate MoltenVK's current support for Vulkan ray tracing extensions (VK KHR ray tracing, VK KHR ray query, VK KHR acceleration structure). Study Metal's ray tracing API starting from Metal 2.3 (MTLAccelerationStructure, MTLIntersectionFunctionTable). Identify the gaps between Vulkan and Metal ray tracing models. Look at existing implementations in other portability layers or prototypes. Understand the threading and memory management implications. Propose a design for mapping Vulkan ray tracing concepts to Metal.
