- The new 16_Raytracing unit test shows a simple cross-platform path tracer. On iOS this path tracer requires A11 or higher. It is meant to be used in tools in the future and doesn't run in real-time.
To support the new path tracer, the Metal raytracing backend has been overhauled to use a sort-and-dispatch based approach, enabling efficient support for multiple hit groups and miss shaders. The most significant limitation for raytracing on Metal is that only tail recursion is supported, which can be worked around using larger per-ray payloads and splitting up shaders into sub-shaders after each TraceRay call; see the Metal shaders used for 16_Raytracing for an example on how this can be done.
