Ray tracing seems to be all the rage at GDC this year, so AMD has announced Radeon-Rays, an open source ray tracing SDK. From what I understand, it's basically them making a big splash over a re-named and updated AMD FireRays with Vulkan support.
Here's what they said about it:
Radeon-Rays is a GPU intersection acceleration library with basic support for heterogeneous systems. AMD developed Radeon-Rays to help developers get the most out of AMD GPUs and CPU or APUs, as well as save them from maintaining hardware-dependent code. Radeon-Rays exposes a well-defined C++ API for scene construction and performing asynchronous ray intersection queries. The current implementation is based on OpenCL, which means Radeon-Rays supports execution on all platforms conforming to the OpenCL 1.2 standard. It is not limited to AMD hardware or a specific operating system. Radeon-Rays can be easily distributed and through its API helps assure compatibility and best performance across a wide range of hardware platforms.
Direct Link
It's nice to see AMD continue to put their stuff out in the open, with it not being tied to their hardware and available for anyone to use. You can find it on GitHub with some other info available in this post on the GPUOpen site.
They also have the "Baikal initiative", an open source (MIT license) GPU-based global illumination renderer that initially started as a sample application for showing off Radeon-Rays, which has since evolved into a fully functional rendering engine.
Thanks for the tip, mirv!

Quoting: ShmerlGood, that should answer the hype that MS are trying to create with their lock-in.
More likely in relation to Nvidia's recent RTX demos with their Volta cards.

Whats Microsoft upto now? I admit I dont follow much of the goings on in windows world as I only use it for work and nothing else so have no need to hunt news about it out.

Spreading lock-in, as usual.

Quoting: CybolicIn the meantime, isn't Blender doing almost the same with their realtime Eevee renderer? I know Eevee is not technically a ray tracer, but isn't it pulling similar tricks?Any Blender users checked out AMD's ProRender yet?
Also the new, upcoming lightmapper for Unity seems to be making use of RadeonRays:

I wonder how cross platform these technologies really are? I wouldn't be surprised if the optimization effort went mostly towards their own hardware. :)

Does AMD's method require new hardware, is NV claims just because Volta has great 16FP precision (up to 125 tflops apparently at fp16).
