Khronos held an OpenXR panel at the 2017 VRDC session (GDC) with developers Yuval Boger, Joe Ludwig, Kaye Mason, Paul Pedriana and Nick Whiting. The panel provided new updates on the goals, content and status of the effort to create a widely accepted VR API for developers called OpenXR. Learn more about OpenXR or watch the video on Youtube.
Vulkan render pass Multipass optimization has been implemented on ARM Mali to improve deferred shading in Vulkan. The video showcases a 20% reduction in frame time compared to the classic Vulkan Multiple Render Targets implementation.
Join Khronos Seattle chapter leader Tim Reha on stage along with Joe Ludwig, developer at Valve (Khronos member), Stephanie Hurlburt co-founder of Binomial (Khronos Member), Ryan Wang from Outpost Capital, and Vinay Narayan from HTC Vive (Khronos Member).
Last year at GDC 2016, Khronos launched the Vulkan 1.0 specification and the Khronos members released first Vulkan drivers and SDKs. Just a year later, at GDC 2017 Unity announced the Unity 5.6 release with the built-in Vulkan renderer. With this, Unity showed not only its support to Vulkan but also to developers that expects the best from Unity. This blog covers the topics presented in the ARM Sponsored Talk at GDC 2017 related with Vulkan integration in Unity. The full talk video is also available in the GDC Vault.
Khronos made videos of three presentations from Codeplay at the Khronos Booth. The videos cover "Heterogeneous C++ dispatch: Comparing SYCL to HPX, KoKKos, & Raja, "Khronos SYCL Parallel STL Open-source Project" and "Getting Your Hands on SYCL Using the ComputeCpp Community Edition"
The LibRetro crew is now working on a Vulkan renderer for a PlayStation One emulator. They have a Vulkan renderer working for the Beetle PSX, but the code hasn't been published yet. In the past few days the LibRetro crew uploaded some YouTube videos showing the Vulkan-renderered PlayStation One emulator in action.
Vulkan API supports multithreading, which is particularly important for mobile platforms. Multithreading enables the system to balance the workload across multiple CPUs, allowing for lower voltage and frequency. The results give considerable energy savings compared to OpenGL ES API. In this video from ARM, you can see just how big a difference there is between OpenGL ES and Vulkan.
