The Khronos Group has published a maintenance release to OpenGL 4.6 and OpenGL ES 3.2 with bug fixes from GitHub, the old Khronos Bugzilla issue tracker and from internal issues. OpenGL 4.6 changes are in the OpenGL Specification Core with Changes PDF starting on page 736. OpenGL ES 3.2 changes are in the OpenGL ES 3.2 Specification PDF on page 539.
RenderDoc 1.5 has been released. Changes include: SPIR-V reflection and disassembly has been refactored to be more reliable and is based on the publicly available grammar json; Vulkan has a new replay-time optimisation which takes advantage of the above replay options dialog; OpenGL has a low-memory optimisation to defer copying initial contents of textures and buffers that are rarely modified; Support for twenty-one (21) Vulkan extensions have been added; Support for fifteen (15) OpenGL extensions have been added along with whitelisting of some OpenGL ES extensions that were already supported. A complete list of changes and improvements is available in the Latest release notes.
Basemark GPU 1.2 adds iOS and macOS to our list of already supported operating systems: Android, Windows, and Linux. We include OpenGL ES 3.1, OpenGL 4.5, Vulkan 1.0, DirectX 12 and Metal. With the new features in Basemark GPU 1.2, you will be able to analyze and compare the 3D graphics performance of smartphones, tablets, notebooks, Windows and Linux desktop PCs, etc.
With the release of virglrenderer 0.8.0, getting accelerated OpenGL within a virtual machine (VM) made a big leap forward. One specific aim was to support hosts that support only OpenGL ES to a point that within the VM guest also OpenGL 4.3 applications can be run. An aim that was fully achieved as we can now run games like Alien Isolation within qemu on certain devices that support only OpenGL ES 3.2 and a number of extension.
The Khronos Group BOF day is today, July 31. For those folks that really wanted to catch some of the BOF Day sessions, but couldn’t make, we have it covered for you. Starting at 9AM PT, the morning livestream will start on YouTube. The afternoon sessions will be on a second afternoon livestream also on YouTube. Learn more about the Khronos Group BOF Day and all of the various sessions on our SIGGRAPH 2019 event page.
SIGGRAPH is next week! The conference is July 28-August 1. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR and Vulkan) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Title sponsor NVIDIA, Beer Sponsor LunarG, and Demo sponsor Cesium, for making possible the Khronos Networking Reception at the end of the day.
Arm Mobile Studio provides free tools for tracing OpenGL ES, Vulkan and OpenCL API calls, to help you optimize application performance and system resources. Learn more at the Arm Webinar on April 23. The webinar will be made available online after the event.
Arm Mobile Studio is a suite of free-to-use tools which help game and app developers to reach more of the mobile market by efficiently optimizing and debugging high-end content for all Android devices. It includes the Arm Graphics Analyzer to trace graphics performance issues easily, and Arm Streamline performance analyzer, for a whole-system view of performance to determine bottlenecks quickly across both the CPU and GPU. Arm Mobile Studio supports frame-by-frame analysis of OpenGL ES and Vulkan content and lets you trace Vulkan, OpenGL ES, EGL and OpenCL API calls easily in your game from within the Unreal game engine.
Khronos will be holding their Annual GDC Developer Day Sessions on March 19th in Moscone West Room 2020. The complete schedule is available online:
glTF and WebGL - 10:00am – 11:00am
OpenXR – State of the Union – 11:20am – 12:20pm
Vulkan – State of the Union - 1:20pm – 2:20pm
Making Use of New Vulkan Features – 2:40pm – 3:40pm
Bringing Fortnite to Mobile with Vulkan and OpenGL ES – 4:00pm – 5:00pm
Ubisoft’s Experience Developing with Vulkan – 5:30pm – 6:30pm
Running all day March 18-19 will be the Khronos OpenXR Table at VRDC. Finally on March 20th starting at 6:30pm, there will be the annual WebGL/WebVR Meetup to be held in Galvanize. In past years there were over 200 people attending with only standing room and people being turned away. If you want to get in, show up early. This event will be live streamed on the Silicon Valley WebGL group on Facebook.
If you are attending GDC 2019, be sure to mark March 19th in your calendar. Khronos will be hosting the annual Developer Day sessions in the Moscone West, Room 2020 from 10am to 6:30PM. This year there will be six (6) sessions covering glTF, WebGL, OpenXR, Vulkan and OpenGL ES. There will also be an OpenXR table at VRDC where you can learn more about OpenXR, talk with OpenXR working group members, and learn how your company can implement or join in the development of this important industry standard. The Khronos Group is once again sponsoring the WebGL/WebVR Meetup. Last year we had over 200 RSVPs and an amazing lineup of speakers. Join Khronos member Patrick Cozzi (Cesium) and other speakers for this gathering of the Silicon Valley WebGL/WebVR meetup group.
TensorFlow announced that you will now be able to leverage mobile GPUs for select models with the release of developer preview of the GPU backend for TensorFlow Lite. This new backend leverages. OpenGL ES 3.1 Compute Shaders on Android devices.
In a recent update, Diligent Engine now gives applications direct control of state transitions in Vulkan API and DirectX12. Diligent Engine includes support for Vulkan and OpenGL 4.2 on Win32 and Linux, as well as OpenGL ES 3.0 on iOS and OpenGL 4.1 on macOS.
Basemark has releases version 1.1 of the its multi-platform graphics hardware evaluation tool Basemark GPU for enthusiasts and professionals alike. Basemark GPU 1.1 Benchmark offers unparalleled, objective comparisons between Vulkan, OpenGL, OpenGL ES and now DirectX 12 for graphics performance analysis across both mobile and desktop platforms.
Shader Conductor is one of several open-source projects for going from one shading language to another. With Microsoft’s Shader Conductor the focus is on converting HLSL to GLSL or SPIR-V (OpenGL/Vulkan), ESSL (OpenGL ES), MSL (Apple Metal), and older HLSL shader models. Shader Conductor can handle all shader stages, including geometry and compute shaders. Learn more about this new Open Source project from Microsoft.
Samsung has announced an enhanced iteration of the Vulkan API, which offers a 10% performance improvement as compared to the OpenGL ES. Samsung has also announced new features for GPUWatch, a tool that aids developers monitor and measure performance between Vulkan and OpenGL ES.
