Vulkan Propulsion Group announced Vulkan’s ray-tracing technology tonight, which will be the industry’s first cross-platform, cross-system open-light tracing API, with AMD, NVIDIA and Intel also announcing their support. From the 2018 NVIDIA launch Turing GPU calculation, the PC platform supportreal light chase has been 2 years, this year with the new host to support light pursuit, AMD RDNA2 graphics card release, the full popularity of light pursuit technology is also on the way.
Previous light pursuit is mainly based on the Windows platform, using the DXR optical pursuit standard in Microsoft DX specification, AMD and NVIDIA will be based on the development of their own GPU optical pursuit scheme.
Compared with Microsoft’s DX12 specification, Vulkan has become so popular in recent years that it has been able to virtually unify other platforms than Windows, including Android, although it has not previously supported light-chasing technology.
The Khronos Group, which has been working with the Ray Tracing Task Sub Group since 2018 to advance light-chasing technology, is now ready to come up with its own light-chasing solution.
Now the Vulkna light chase technology is the first stage, the official did not release specific performance details, issued two “Wolfenstein: Youngblood” game of the comparison, you can blindly guess that that is open edgy.
The answer was revealed, and the second one was followed by Vulkan, who said the metal on the wall, the floor of the door and the reflection near the window were enhanced, and the overall lighting effect in the scene was enhanced. (But I didn’t see any significant changes)
However, for Vulkan, due to its cross-platform features, it is expected to become the most popular light pursuit technology in the future, and the Khronos Group announced that it will be compatible with Microsoft’s DXR optical pursuit technology for developers to port. To this end, developers are allowed to use the HLSL shader language to create Vulkan’s Ray Tracing SPIR-V shader.
It’s worth noting that after the announcement of the Vulkan version of Light Pursuit, AMD, Intel and NVIDIA, as well as Imagination Technologies, which also move disserviced the GPU, also announced their support for the first time, and it seems likely that Vulkan will unify future light-chasing game development.
