Collabora has announced that it has partnered with Microsoft DirectX engineers to build OpenCL and OpenGL mapping layers, in order to bring OpenCL 1.2 and OpenGL 3.3 support to all Windows and DirectX 12 enabled devices.
According to the team, this work builds on a lot of previous work. First and foremost, it is building this by using Mesa 3D, with the Gallium interface as the base for the OpenGL layer, and NIR as the base for the OpenCL compiler. Collabora is also using LLVM and the SPIRV-LLVM-Translator from Khronos as the compiler front-end.
In addition, the team is taking advantage of Microsoft’s experience in creating their D3D12 Translation Layer. Moreover, it will take advantage of its own experience from developing Zink.
Mesa 3D is an open source implementation of several graphics technologies, including OpenCL and OpenGL. The OpenGL implementation in Mesa promises to be robust. It will also be used as the base for several industry-strength OpenGL drivers from multiple GPU vendors.
Among other things, Mesa consists of several API implementations (called state-trackers) as well as the Gallium low-level driver interface. It’s worth noting that the Gallium interface hides a lot of the legacy OpenGL details. It also translates OpenGL calls into something that looks more like modern GPU primitives.
Lastly, a GPU vendor only has to implement a D3D12 driver for their hardware in order to support all three APIs. This mapping layer will also serve as a starting point in porting older OpenCL and OpenGL applications over to D3D12.

While he is a die-hard PC gamer, his gaming roots can be found on consoles. John loved – and still does – the 16-bit consoles, and considers SNES to be one of the best consoles. Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2. John has also written a higher degree thesis on the “The Evolution of PC graphics cards.”

Vulkan for everything and DX12 for Most win 10 games.
OPGL is now too old
Even 4.6 old as hell… wtf?
The only question on John’s mind is,
But does it run
CrysisResident Evil nude mods? ?Some Off topic article John…You might find this interesting. It’s about RTX…Even non-RTX GPUs might benefit from RAY TRACING it seems…

Nvidia released a new developer toolkit called Nvidia’s RTX Global Illumination SDK v1.0 (RTXGI), which aims to provide all the tools necessary to provide scalable lighting solutions across all DirectX Ray-Tracing compliant GPUs without prohibitive requirements.
Different Ray-Tracing characteristics can be integrated scaling from basic lighting to the best lighting that could be simulated, maintaining the optimization of resources and providing pure dynamic lighting, not pre-calculated as currently used.
“The fundamental advantage here is that it’s a scalable SDK that allows low-end hardware that may not have ray tracing capabilities to produce global illumination,” Tony Tamasi, SVP of content and technology at Nvidia, says. “Then hardware that has ray tracing capability gets progressively better, meaning the updates are higher quality and more frequent.
“It works off of very traditional flows the game developers are very familiar with, which is light probes. Think of it as baked lighting. But then it allows you to trace rays from those light probes so you get more accurate lighting, more real-time updates, and you don’t get some of the artifacts that you normally get through those light probes, such as light leaking.”
Key Highlights of the RTXGI SDK v1.0 release include:
Full Source Code. Providing full source code so you can easily integrate RTXGI into your tools and customize it to your specific needs.
No Baking, No Leaks. Dramatically speed up your iteration time with real-time ray traced lighting. No more waiting for bakes. No more obsessing over light probe positioning either; no light or shadow leaking.
Any DXR GPU. RTXGI runs on a broad range of hardware. All DXR-enabled GPUs are supported, including GeForce RTX 20 Series, GTX 1660 Series, and GTX 10 series.
Tuned & Optimized. Easy to integrate and fast to provide results, right out of the box. Performance optimized to fit in 60Hz frame budgets.
According to Nvidia, you can have a small amount of Ray-Tracing with graphics card that does not even have dedicated hardware for it, and still get better lighting than conventional, with playable performance. Then, with more powerful hardware with dedicated hardware for RT, you can get better effects and higher performance. This scalability will make it possible to use the technology in all ranges, and not have to worry about which graphics will be used by the end user. It will be compatible with any graphics that supports DirectX Ray-Tracing, so it is not exclusive to Nvidia. It can also be used in the future on Navi 2X and Intel Xe, which makes this SDK even more interesting. The Khronos Group announced official Vulkan RT ray tracing earlier this month, and we can expect to hear more from game devs making the most of that API later in the year. As for hardware, AMD will bring its own spin on the ray tracing formula with RDNA 2.0 in discrete Navi 2X graphics cards, the Xbox Series X, and the PlayStation 5 in the Winter.
