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.
Magic Leap has made the session on Seedling from Insomniac Games available to the public. Featuring Joel Bartley, lead gameplay programmer for Insomniac Games, and Michael Liebenow, lead software engineer for Magic Leap, the session examines how to integrate a 3D engine into an app using the Vulkan API. "We support two low-level rendering APIs, both Vulkan and OpenGL, but we feel that Vulkan provides more opportunities for optimization, which is especially important when you're trying to get all the performance you can out of a mobile system, and that is one of the main reasons why we recommend Vulkan for your development," said Liebenow during the session.
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.
The AMDVLK Vulkan Radeon driver updates include support for the VK_EXT_inline_uniform_block extension, which lets uniform blocks be directly backed by descriptor sets. Code clean up and other updates can be viewed on Phoronix and directly from the source on Github GPUOpen-Drivers/AMDVLK.
Unreal Engine 4.21 continues their pursuit of greater efficiency, performance, and stability for every project on any platform. With the help of Samsung, Unreal Engine 4.21 includes all of the Vulkan engineering and optimization work that was done to help ship Fortnite on the Samsung Galaxy Note 9 and is 100% feature compatible with OpenGL ES 3.1. Projects that utilize Vulkan can run up to 20% faster than the same project that uses OpenGL ES.
Zink is an OpenGL implementation on top of Vulkan. Or to be a bit more specific, Zink is a Mesa Gallium driver that leverages the existing OpenGL implementation in Mesa to provide hardware accelerated OpenGL when only a Vulkan driver is available.
Qualcomm has introduced the new Qualcomm Snapdragon 675 Mobile Platform. The Snapdragon 675 offers outstanding gaming, a leap in artificial intelligence (AI) capability and a cutting-edge camera. Premium features in the Snapdragon 675 are enabled by the Qualcomm AI Engine, Qualcomm Spectra ISP, Qualcomm Kryo CPU and Qualcomm Adreno GPU. A number of specific games and game engines have been optimized including Unity, Unreal, Messiah, and NeoX. Qualcomm Technologies also supports popular tools and APIs, including Vulkan, OpenGL 3.2, OpenCL, and Snapdragon profiler.
LunarG now delivers native Ubuntu Linux packages for all the elements in the Vulkan SDK in addition to the Linux SDK tarball. Follow the Ubuntu Packages link on the LunarXchange SDK web page to gain access to the native Ubuntu Linux packages. These packages will install pre-built SDK binaries on a system running Ubuntu Linux and contain all the LunarG Vulkan SDK components at the latest available version. For Ubuntu Linux users, this is the most convenient way to get the Linux SDK content since you will not need to build any binaries yourself. Headers, libraries, and tools are included and prebuilt. Read the LunarG blog for more details.
The AMD Developer Tools team has been busy working on many new tools, some of which replicate functionality found in older versions of CodeXL. To limit confusion for our users, several major components have been removed from CodeXL. Graphics Frame Analysis for DirectX 12 and Vulkan applications have been removed and can now be found in the following AMD and third-party tools:
Radeon GPU Profiler, RenderDoc, Microsoft PIX.
Vulkan could improve the limited battery life on the Oculus Go and help Oculus deliver a console level experience on the Quest. While a mobile chip is unlikely to ever deliver the same performance as a home console or gaming PC, Vulkan may help narrow the gap and deliver more realistic graphics than OpenGL would.
The 2018 X.Org Developer's Conference (XDC2018) videos have now been posted online. XCD 2018 saw many Khronos members sponsor this conference, including Igalia, AMD, Arm, COLLABORA, Google, NVIDIA, Intel and Valve. The talks covered Vulkan, OpenGL, OpenGL ES, OpenCL, SPIR-V, GLSL and OpenXR. We've compiled a list of all the videos discussing these Khronos standards here, or you can watch all the videos from the conference on the X.Org Foundation YouTube channel.
NVIDIA’s new Turing GPU unleashed real-time ray-tracing in a consumer GPU for the first time. Since then, much virtual ink has been spilled discussing ray tracing in DirectX 12. However, many developers want to embrace a more open approach using Vulkan, the low-level API supported by the Khronos Group. Vulkan enables developers to target many different platforms, including Windows and Linux, allowing for broader distribution of 3D-accelerated applications. NVIDIA’s 411.63 driver release now enables an experimental Vulkan extension that exposes NVIDIA’s RTX technology for real-time ray tracing through the Vulkan API. Head over to the NVIDIA blog to read all about this update.
GLOVE (GL Over Vulkan) is a cross-platform software library that acts as an intermediate layer between an OpenGL ES application and Vulkan. GLOVE is focused towards embedded systems and is comprised of OpenGL ES and EGL implementations, which translate at runtime all OpenGL ES / EGL calls & ESSL shaders to Vulkan commands & SPIR-V shader respectively and finally relays them to the underlying Vulkan driver.
A libre-licensed software implementation of Vulkan has started up again. Originally started in c++ in 2017, for a reimplementation Rust has been chosen for its concurrency and memory-safety features, and Rust's LLVM support makes it highly portable. With OpenGL having both llvmpipe and MesaGL for fallback and testing purposes, it seems strange that there does not exist a corresponding Reference Implementation for Vulkan: the only implementations available are in hardware, making it extremely challenging for anyone considering entering the market. Kazan helps fill that gap. Sponsorship of this entirely libre-licensed project welcomed.
