The schedules for the all-day Khronos BOF Blitz and famous BOF Blitz After Party are now online. Featuring four BOFs on Wednesday July 27th, and a 5th BOF on Tuesday July 26th for Khronos Chapters. We've also compiled a list of all the SIGGRAPH sessions, courses, workshops and BOFs that contain Khronos Technology. Unsurprisingly there is a ton of Vulkan stuff going on this year. Checkout the event page today. Hope to see lots of you in Anaheim during SIGGRAPH!
Over on the Imagination Technologies developer blog, a new tutorial on adding ray tracing to an OpenGL ES based deferred lighting system.
The Lightweight Java Game Library released its final build of version 3, in development since 2012. Version 3 provides API bindings to Java for many libraries including Khronos APIs such as OpenGL, OpenGL ES, EGL, OpenCL and Vulkan. LWJGL powers many cross platform applications including the popular game Minecraft.
Tom's Hardware has a nice review on mobile GPUs getting ready for 'Daydream' VR. Among the technologies being used are Khronos' ASTC specification and OpenGL ES. The Adaptive Scalable Texture Compression (ASTC) technology supported by ARM’s latest Mali and other recent GPUs on the market will reduce bandwidth requirements while still delivering decent graphics quality. On the software side, ARM has been optimizing its drivers to reduce latency and ensure fast context switching that is necessary for VR. ARM also enabled a few more OpenGL ES extensions to support efficient rendering to multiple views for both stereo and foveated rendering. Qualcomm's Snapdragon 820 SoC, which comes with the Adreno 530 GPU, has been optimized for VR. It has support for 3D stereoscopic and foveated rendering, the latest graphics APIs such as OpenGL ES 3.2 and Vulkan, and 360-degree 4k video decoding at 60fps.
Google has released the latest Android Studio 2.0, the official IDE for Android development. Among many of the improvements is an added a preview of the new GPU Debugger. For graphics intensive applications, you can now visually step through your OpenGL ES code to optimize your app or game.
Futuremark has released a new upgraded version of the benchmarking tool named Slingshot Extreme. The new version of the program comes packing hardware accelerated OpenGL ES 3.1 API and Metal API for Android and Apple respectively. This is a major upgradation over the last version as well as the 2013 build named Ice Storm which came with 720p tests and used OpenGL ES 2.0 as well as the last release that tested 1920x1080p and used OpenGL ES 3.0.
Learn the key OpenGL ES 3.x API features and extensions, as well as best practises on how to optimize your OpenGL ES 3.x application for the ARM Mali architecture.
Shaderific version 4.0 is now available. Shaderific is an educational app for iPad, iPhone and iPod touch that makes it possible to write, compile and test OpenGL ES 2.0 and OpenGL ES 3.0 shader programs directly on any iOS device. Version 4.0 adds support for iPad Pro taking full advantage of the bigger screen as well as support for Multitasking with Slide Over and Split View. To complement the existing anaglyph 3D rendering capabilities a new 3D mode has been added for left-right stereo image rendering. Furthermore, rendering on an external display connected via Lightning Digital AV Adapter is now supported in addition to the default screen mirroring.
Fast UI Draw, source code available on github, has now been open sourced. Fast UI Draw is a high performance Canvas renderer that is tuned for Intel GPU's (but can work for other GPU's) that under significant load is much faster than many other Canvas renderers. Fast UI Draw when running has very few GPU states, very few draw calls even under very complicated scenes. In addition, Fast UI Draw has a unique methodology to handle clipping that allows for applications to have rotations, projection, and clipping without incurring significant CPU load from setting, saving or restoring clipping. Fast UI Draw is available under the MPLv2 and a very alive project undergoing active development.
The newly-opened Mesa 11.3-devel code-base already has support for another OpenGL ES 3.2 extension. The GL_OES_shader_image_atomic is now supported by mainline Mesa with all of the drivers that support the GL_ARB_shader_image_load_store extension.
