Intro and NNEF 1.0 Finalization
SIGGRAPH 2018 is a huge computer graphics expo that occurs in a seemingly random host city around North America. (Asia has a sister event, called SIGGRAPH Asia, which likewise shuffles around.) In the last twenty years, the North American SIGGRAPH seems to like Los Angeles, which hosted the event nine times over that period, but Vancouver won out this year. As you would expect, the maintainers of OpenGL and Vulkan are there, and they have a lot to talk about.
- NNEF 1.0 has been finalized and released!
- The first public demo of OpenXR is available and on the show floor.
- glTF Texture Transmission Extension is being discussed.
- OpenCL Ecosystem Roadmap is being discussed.
- Khronos Educators Program has launched.
I will go through each of these points. Feel free to skip around between the sections that interest you!

While the Vulkan update headlines the Khronos Group’s presence at GDC 2017, they also re-announced their VR initiative, now called OpenXR. This specification wraps around the individual SDKs, outlining functionality that is to be exposed to the application and the devices. If a device implements the device layer, then it will immediately support everything that uses the standard, and vice-versa.
OpenVR was donated by Valve, leading to OpenXR...
... because an X is really just a reflected V, right?
Like OpenGL and Vulkan, individual vendors will still be allowed to implement their own functionality, which I’m hoping will be mostly exposed through extensions. The goal is to ensure that users can, at a minimum, enjoy the base experience of any title on any device.
They are aiming for 2018, but interested parties should contribute now to influence the initial release.
