AMD Brings Ray Tracing Support In Its Open-Source Vulkan

Over the last week, the AMD Vulkan graphics driver, AMDVLK GPUOpen, has increased support for 64-bit ray tracing for its Radeon RX 6000 GPUs. This includes both desktop/mobility GPUs & APUs utilizing the RDNA 2 graphics architecture. All AMD Vulkan drivers across all platforms, such as Mesa3D RADV, AMDVLK GPUOpen, and AMDGPU-PRO, will now support hardware ray tracing.

AMDVLK GPUOpen, AMD’s open-source Vulkan driver, supports hardware raytracing for RDNA 2 GPUs In Linux

Included in the new updates are the GPU Ray Tracing Library, or GPURT, which will consist of the Bounding volume hierarchy (BVH) build and sort processing found in ray tracing using shaders such as HLSL. This library will allow a standard library to initiate more uniformity and enhance graphics rendering. The new library will also be compatible with DirectX 12 DXR.

The GPU Ray Tracing (GPURT) library is described as “a static library (source deliverable) that provides ray tracing-related functionalities for AMD drivers supporting DXR (DirectX 12) and the Vulkan® RT API.” The library is constructed on the company’s Platform Abstraction Library (PAL).

The GPURT library utilizes a C++ interface as its basis. The public interface is divided into multiple header files based on their dependencies and usage. Users interested in the full info on the RDNA 2 GPU Ray Tracing Library (GPURT), along with a breakdown of the structure, can find out more on the official GitHub page.
