The Khronos Group announces from the SIGGRAPH 2017 Conference the immediate public availability of the OpenGL 4.6 specification. OpenGL 4.6 integrates the functionality of numerous ARB and EXT extensions created by Khronos members AMD, Intel, and NVIDIA into core, including the capability to ingest SPIR-V shaders. Learn more about this release. Khronos encourages and welcomes all feedback on the new specification.

Vulkan working group has released a major Vulkan 1.0 specification updateThe 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.

Khronos Releases OpenVX 1.2 Specification The Khronos Group announces the immediate release of the OpenVX 1.2 specification for cross-platform acceleration of computer vision applications and libraries. OpenVX is a high-level, graph-based API targeted at real-time mobile and embedded platforms. This open, cross-platform, royalty-free standard enables performance-portable, power-optimized computer vision applications such as face, body, and gesture tracking, smart video surveillance, autonomous driver assistance systems, visual inspection, and robotics. Core OpenVX 1.2 has significantly expanded functionality, including conditional execution, feature detection, and classification operations.

Khronos Finalizes glTF 1.0 SpecificationKhronos announced that the glTF™ 1.0 (GL Transmission Format ) royalty-free specification for transmission and loading of 3D content has been finalized for Ratification and is immediately available for use by tools and application vendors. glTF is an efficient, interoperable asset delivery format that compresses the size of 3D scenes and models, and minimizes runtime processing by applications using WebGL™ and other APIs. glTF also defines a common publishing format for 3D content tools and services.

The Khronos Group today announced the ratification and public release of the Khronos Data Format Specification 1.0. This new standard provides precise mechanisms to generate machine-readable format descriptions of repetitive data, such as pixels, enabling standards and software to cleanly communicate and interoperate. This royalty-free specification will be used across multiple Khronos API initiatives, and is open to be used by third party standards and applications.

The Khronos Group today announced the ratification and public release of the SPIR 2.0 provisional specification that provides a non-source encoding, and binary level portability, for OpenCL 2.0 device programs. SPIR (Standard Portable Intermediate Representation) is the industry's first open, cross-platform Intermediate Representation standard for portable heterogeneous parallel computing and is based on LLVM IR. SPIR enables developers to avoid exposing sensitive kernel source and enables a diversity of language front-ends to easily target OpenCL platforms and devices in addition to OpenCL C. Visit the SPIR specification in the OpenCL registry.

The Khronos Group today announced the immediate release of the OpenGL® ES 3.0 specification, bringing significant functionality and portability enhancements to the industry-leading, royalty-free 3D graphics API that is used on the majority of the world’s smartphones and tablets. OpenGL ES 3.0 provides access to state-of-the-art GPU functionality with portability across diverse mobile and embedded operating systems and platforms. OpenGL ES 3.0 is backwards compatible with OpenGL ES 2.0, enabling applications to incrementally add new visual features to applications. The full specification and reference materials are available for immediate download at http://www.khronos.org/registry/gles/.

The Khronos Group today announced the immediate release of the royalty-free, Adaptive Scalable Texture Compression (ASTC™) LDR extension specification, defining a new, highly flexible texture compression scheme for developers using both the OpenGL® ES and OpenGL® 3D graphics APIs. ASTC is an exceptionally efficient compression technology which allows encoding of for a wide variety of texture formats at bit-rates of 8 bits per pixel to below 1 bit per pixel. ASTC is published as a Khronos extension, KHR_compressed_texture_astc_ldr, which is available from the Khronos website.

The Khronos Group today announced the release of OpenMAX™ IL 1.2 as a provisional specification. OpenMAX IL is a royalty-free, cross-platform C-language API for integration of multimedia components into media frameworks to simplify deployment of audio/video encoders/decoders, camera control, and audio, video and image processing algorithms across diverse platforms. OpenMAX IL 1.2 is a backward compatible upgrade that includes dynamic buffer allocation, improved media graph management, in-band signaling, enhanced audio video synchronization, a wider range of standard components and enhanced camera control capabilities together with many other improvements and clarifications to increase interoperability between media processing components. The specification has been released in provisional form to enable developers and implementers to provide feedback before specification finalization. The OpenMAX IL 1.2 provisional specification is available for immediate download.
