Creates a window in preparation of rendering Direct3D 12 content.Renders a simple triangle using Direct3D 12.Demonstrates the usage of a bundle for rendering using Direct3D 12.Demonstrates how to use constant buffers to pass data to the GPU used for rendering in Direct3D 12.Demonstrates how to apply a texture to a triangle using Direct3D 12.YYCreating a basic Direct3D 12 componentD3D12BundlesDemonstrates frame buffering and synchronization best practices as well as rendering a simple mesh using bundles.YYD3D12MultithreadingAn example of how to build a multithreaded capable application.YND3D12nBodyGravityDemonstrates how multi-engine can be used to do asynchronous compute work alongside 3D work on the same GPU.YYMulti-engine n-body gravity simulationD3D12PredicationQueriesDemonstrates occlusion culling using query heaps and predication.YYPredication queriesD3D12DynamicIndexingDemonstrates the dynamic indexing capabilities of DirectX 12 and HLSL.YYDynamic Indexing using HLSL 5.1D3D1211on12Demonstrates basic usage of the 11on12 layer. This sample renders text using D2D using the Direct3D 11 API on a Direct3D 12 11on12 device.YYD2D using D3D11on12D3D12ExecuteIndirectDemonstrates compute engine culling in conjunction with the execute indirect feature to only render objects that pass the culling test.YYIndirect drawing and GPU cullingD3D12PipelineStateCacheDemonstrates Pipeline State Object (PSO) caching.YYD3D12FullscreenDemonstrates how to handle fullscreen to windowed transitions and window resizing in DirectX 12.YYD3D12HeterogeneousMultiadapterDemonstrates how to share workloads amongst multiple heterogenous GPUs using shared heaps.YYD3D12ReservedResourcesDemonstrates the use of reserved (tiled) resources. In this sample a quad is textured with a reserved resource containing a full mip chain.YYD3D12ResidencyThis is intended as a low-integration-cost solution to managing your Direct3D 12 heaps and committed resources, using memory management techniques from Direct3D 11.YYD3D12SmallResourcesDemonstrates the use of small placed resources, showing the potential memory savings gained using placed resources (with a 4K alignment) over committed and reserved resources (with a 64K alignment).YY Direct3D 12 Programming Guide D3D12 Code Walk-Throughs --> Feedback Additional resources In this article

OpenXR Vulkan/OpenGL on Direct3D 12 interoperability layerThis software enables OpenXR apps developed for Vulkan/OpenGL to work with OpenXR runtimes that have support for Direct3D 12 and not Vulkan/OpenGL.DISCLAIMER: This software is distributed as-is, without any warranties or conditions of any kind. Use at your own risks.SetupDownload the latest version from the Releases page. Find the installer program under Assets, file OpenXR-Vk-D3D12.msi.For troubleshooting, the log file can be found at %LocalAppData%\XR_APILAYER_MBUCCHIA_vulkan_d3d12_interop.log.LimitationsThis has only been tested with Windows Mixed Reality.This has only been tested with NVIDIA and AMD video cards.Vulkan support has been tested with BeamNG, the X-Plane 12 Demo, the HelloXR sample app from Khronos, Unity 2021, Godot 4, Adobe Substance 3D and Enscape 3D.OpenGL support has been tested with HelloXR sample app from Khronos, Autodesk VRED 2024 and Paraview.It is compatible with OpenXR Toolkit.Known issuesApplications using legacy XR_KHR_vulkan_enable must enable Vulkan timeline semaphores at device creation time. VkPhysicalDeviceTimelineSemaphoreFeatures timelineSemaphoreFeatures{ VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TIMELINE_SEMAPHORE_FEATURES}; timelineSemaphoreFeatures.timelineSemaphore = true; // Chain timelineSemaphoreFeatures to your VkDeviceCreateInfo struct.Applications using OpenGL with an OpenXR runtimes without support for mutable FOV (as reported in XrViewConfigurationProperties) and applications using OpenGL and rendering quad layers will have rendering upside-down. The necessary code to Y-flip the image is not implemented.If you are having issues, please visit the Issues page to look at existing support requests or to file a new one.OpenXR ConformanceThe API layer passed all OpenXR conformance tests (at v1.0.26.0) with Vulkan as the graphics API and with Windows Mixed Reality at the backing OpenXR runtime.How does it work?This API layer sits between any OpenXR application and the OpenXR runtime. It enhances the currently selected OpenXR runtime with the OpenXR extensions necessary for Vulkan support (XR_KHR_vulkan_enable and XR_KHR_vulkan_enable2). It uses the OpenXR runtime's Direct3D 12 support to efficiently bridge the application's Vulkan rendering to Direct3D 12. This processes does not add any overhead: the swapchains (drawing surfaces) requested by the application in Vulkan formats are imported as-is from Direct3D 12, there is no additional copy nor composition phase. Upon submission of the rendered frame, a simple fence synchronization primitive is inserted in the GPU queue shared with the OpenXR runtime, which will not block the application's rendering loop.Same principle applies to OpenGL support.
