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.
To coincide with the release of OpenGL 4.6, NVIDIA is pleased to announce the immediate availability of our OpenGL 4.6 beta drivers for Windows and Linux. These drivers provide full OpenGL 4.6 and GLSL 4.60 functionality and also add support for the GL_KHR_parallel_shader_compile extension released today. This beta release is based on the published OpenGL 4.6 Khronos Specification, and is expected to pass the OpenGL 4.6 Khronos Conformance Testing Process when available. Current conformance status can be found online. Further details and driver downloads are available at the NVIDIA OpenGL driver website.
The Khronos Group has updated the Birds of a Feather schedule and speaker list. 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.
The entire WebGL Insights book is now available for free in PDF format with permission from CRC Press. The 23 chapters on advanced WebGL topics from 42 authors and 25 reviewers is basically still the only book on _advanced_ WebGL. Get your copy today, and start making awesome WebGL content.
Researchers at CMU and NVIDIA have developed an open source shading language and compiler framework named Spire enhanced to support shader components for high-performance rendering. The Spire compiler can generate either GLSL or SPIR-V output for use with OpenGL and Vulkan based engines. The work interfaces with a modernmini 3D engine that supports equivalent back-ends for both OpenGL and Vulkan. The researchers will present this year’s work at SIGGRAPH next week which builds on a paper from last year’s SIGGRAPH.
Attending SIGGRAPH 2017 next week? OpenGL developers should attend this free NVIDIA session on Monday, July 31 to get the most out of OpenGL on Quadro, GeForce, and Tegra GPUs. Hear from an OpenGL expert at NVIDIA how the OpenGL continues to evolve. See how NVIDIA’s Nsight developer tools make OpenGL development easier for you. Learn how your application can benefit from NVIDIA advancing OpenGL as a cross-platform, open industry standard. See this schedule for a complete list of NVIDIA content at SIGGRAPH.
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.
