The Bullet 2.86 has improved Python bindings, pybullet, for robotics, machine learning and VR, see the pybullet quickstart guide. Furthermore, the PGS LCP constraint solver has a new option to terminate as soon as the residual (error) is below a specified tolerance (instead of terminating after a fixed number of iterations). There are optional multithreaded optimizations, thanks to lunkhound. There is preliminary support to load some MuJoCo MJCF xml files (see data/mjcf),see Bullet VR haptic experiments with a VR glove

3D-Tech News Around The Web / WebGL 2 lands in Firefox
« on: January 29, 2017, 02:35:07 PM »
With the release of Firefox 51, WebGL 2 support has landed! WebGL is a standard API to render 3D graphics in the Web. It is based on OpenGL ES, which is commonly used by mobile games.
To date, we have been able to use WebGL 1 (based on OpenGL ES 2) to render fancy graphics into a <canvas> element. WebGL 2, however, is based on the OpenGL ES 3.0 specification, which introduces new features – many of them aimed at increasing performance and visual fidelity.
Until today, WebGL 2 had been usable behind a flag or in the Developer Edition or Nightly, but with Firefox 51, it’s now unlocked for all users of Firefox on Windows, MacOS, and Linux.
To give you a taste of the content WebGL 2 enables, we’re excited to highlight After the Flood, an interactive WebGL 2 demo by PlayCanvas.

The Khronos Group today announced that it has placed conformance tests for the OpenGL and OpenGL ES open standard APIs for 3D graphics into open source. Khronos has created a new GitHub source repository that will hold test sources for OpenGL and OpenGL ES as well the test suite for Vulkan that was open sourced when Vulkan launched. The unified repository will encourage

General Discussion / Unity3D graphics API selector (for Windows)
« on: January 24, 2017, 11:11:19 PM »
As you might have already noticed Unity 5.6 supports now 7 different graphics APIs which you can build all together in one executable.
Unfortunately you can't select the API in the start window, so you have to use command line options.
Either manually or use following batch. Just replace name of executable.

3D-Tech News Around The Web / Vulkan SDK 1.039 released
« on: January 24, 2017, 07:25:24 PM »
Vulkan SDK Release Notes

  Important Note about loader: The release loader binary is built from different source than provided by the SDK package.  The source the loader is built from will be made publicly available at some point in the near future.  Because of this, the debug loader is still built from the publicly available source and will not exactly match the behavior of the release loader.
Glslang and Driver Issues: Please see the Known Driver Issues section in this document for information about a compatibility issue between glslang and Nvidia drivers.
  Overview of new features in SDK
  • Update loader, parameter validation, and docs to Vulkan version 1.0.39.  This includes the addition of following extensions:
    • VK_KHR_get_physical_device_properties2
    • VK_KHR_shader_draw_parameters
    • VK_EXT_direct_mode_display
    • VK_EXT_display_surface_counter
    • VK_EXT_display_control
  • Additional Vulkan loader changes:
    • Loader now handles dynamic device addition/removal
    • Expanded logging of loader behavior (using VK_LOADER_DEBUG)
    • vkEnumerateInstanceExtensionProperties now filters out unknown instance extensions, since the loader can not support them.
    • LoaderAndLayerInterface document has been updated and re-organized.
    • Latest loader and ICD interface changes
    • New loader and layer interface version negotiation
    • Information on how to support unknown physical device extensions (from a layer or ICD)
  • vktrace has been changed so that the --PMB option defaults to true.
  • The Runtime (RT) installer no longer removes valid layers from registry.
    • Prior to this, layers were only kept in the 'ExplicitLayers' registry key if the API version matched that of the Runtime.
    • Now they will continue to exist in the registry if the layer version is less than or equal to the installing Runtime version.
      • Additionally, if multiple SDKs are present, the Runtime installer will select the highest layer API version that is less than or equal to the highest RT API version.
    • For example, if you:
      • Installed SDKs,
      • Then installed the RT
      • The layers should continue to exist in the registry and be useable.
  • Improved coverage and utility in layer validation tests
  • Scores of bugfixes, new validation checks, and many feature additions

3D-Tech News Around The Web / NVIDIA GeForce Game Ready Driver 378.49
« on: January 24, 2017, 05:04:06 PM »
Game Ready Drivers provide the best possible gaming experience for all major new releases, including Virtual Reality games. Prior to a new title launching, our driver team is working up until the last minute to ensure every performance tweak and bug fix is included for the best gameplay on day-1.  Today we are releasing Game Ready Driver v378.49 providing optimal gaming experience for Resident Evil 7 Biohazard, Conan Exiles early access, and the For Honor closed beta:

Cycles Turbocharged: how we made rendering 10x faster

 Here at Blender Institute we challenge ourselves to make industry quality films while improving and developing Blender and open source pipeline tools.
One of the artistic goals for Agent 327 Barbershop is to have high quality motion blur. Rendering with motion blur is known to be a technical challenge, and as result render times are usually very high. This is because we work with:
  • characters with advanced shaders
  • with hair
  • in indoor environments
  • with complex light setups
  • and lots of mirrors

PIX is a performance tuning and debugging tool for game developers.  It has a long and storied history spanning three generations of Xbox console.  Today we are pleased to announce that a beta release of PIX is now available for analyzing DirectX 12 games on Windows as well.
PIX on Windows provides five main modes of operation:
  • GPU captures for debugging and analyzing the performance of Direct3D 12 graphics rendering.
  • Timing captures for understanding the performance and threading of all CPU and GPU work carried out by your game.
  • Function Summary captures accumulate information about how long each function runs for and how often each is called.
  • Callgraph captures trace the execution of a single function.
  • Memory Allocation captures provide insight into the memory allocations made by your game.
