One of the key differences between OpenGL and Vulkan -and something that needs careful consideration when porting to Vulkan, is the coordinate system. Vulkan requires the right hand NDC space compared to GL that requires the left hand. Learn about the KHR_VK_maintainance1 extension and see how AnKi is flipping the viewport.
Intel has released their Graphics Driver 15.46 to provide launch support, as well as bugfixes, feature updates, Computer Vision and AI application development support, and support for Windows 10 Creator’s Update features. The driver is only for Windows 10 64-bit. Intel has enabled additional OpenCL media extensions, as well as a few preview extensions. In addition, 15.46 brings support for OpenGL v4.5, Vulkan v1.0.38, and programmable sample positions in Direct3D12.
Stephanie Hurlburt, one founder of Khronos member Binomial recently put out a call for beginner-friendly ways to learn Vulkan. The result is a nicely curated list of Vulkan Tutorials that one can call beginner level. Read more about Stephanie's thoughts on learning Vulkan, and then dive in yourself.
ArrayFire announced the release of ArrayFire v3.5, an open source library of parallel computing functions supporting CUDA, OpenCL, and CPU devices. This new version of ArrayFire improves features and performance for applications in machine learning, computer vision, signal processing, statistics, finance, and more. Release notes are available and the source code can be found on Github.
In collaboration with Google, Codeplay is proud to announce the release of a new open-source tool allowing the compilation of OpenCL C language kernels to run on the Vulkan API. The tool, named 'clspv', allows a subset of the OpenCL C language to be targeted at the Vulkan API. This tool allows developers to port code containing more than a million lines of OpenCL C to run on the Vulkan API. The source is available on Github.

Starting with v3.0, Babylon.js supports rendering using WebGL1 and WebGL2 contexts. The support is transparent for developers. By default the engine tries to get a WebGL2 context. If none is available then a WebGL1 one is retrieved. Learn more about Babylon.js v3.0 or get started on Github.
The Vulkan working group has released a major Vulkan 1.0 specification update that adds eighteen new KHR extensions. They include KHR replacements for the experimental KHX_external_memory_* and KHX_external_semaphore_* extensions released earlier this year, incorporating changes based on developer and implementer feedback. The release also adds a set of KHR_external_fence_* extensions. Together, these extensions allow applications to share memory and synchronization primitives across process and API boundaries. Two new extensions, KHR_dedicated_allocation and KHR_get_memory_requirements2, provide more expressive and extensible ways for applications to optimize their GPU memory allocation policies. KHR_16bit_storage, KHR_storage_buffer_storage_class, and KHR_variable_pointer allow Vulkan implementations to accept shader programs containing new programming constructs recently added to the SPIR-V intermediate shading language.
The new extensions are accompanied by a new release of the Vulkan 1.0 conformance test that checks that the new extensions are implemented correctly, and a new Vulkan SDK that provides loader and validation support and a snapshot of a compatible release of the GLSLang shader compiler. All of the new extensions are supported in the latest NVIDIA drivers, and support from other GPU vendors is in progress.

Microsoft announced updates to Paint 3D: Magic select enhancements & drawing tools. Paint 3D also now supports a new industry-wide open standard for 3D file sharing called GLB, a part of gLTF (GL Transmission Format). This allows for faster and more efficient transfer of 3D assets by outputting only one container for all assets, minimizing the file size and the ability to use the files across other programs as a universal format. glTF (GL Transmission Format) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. The glTF specification is managed by the Khronos Group.
The Khronos Group has posted their Birds of a Feather schedule online. If you will be at #SIGGRAPH2017 be sure to visit the BOF Blitz and After Party! BOFs include: OpenVX, NNEF, OpenCL and SYCL; COLLADA; glTF; WebGL; OpenXR; and Vulkan, OpenGL & OpenGL ES to wrap up the day. glTF has just posted their list of speakers, and what a line they have for you in store for you. At the end of the day, be sure to hang around for the BOF Blitz After-Party. The BOFs will be live streamed with video available afterwards, and t-shirts available online, for all those folks not attending.

Games developers know how to engage players and keep them interested, and how to tell stories in a non-linear fashion. And they have for years created content in three dimensions, a basic requirement for VR. Indeed, virtual reality is integrating games and the broader technology industry as never before. “It’s like two continents that were apart, and continental drift is bringing them together,” says Neil Trevett of the Khronos Group, a non-profit industry group.
