Mapping Layers

Component Description Link
OpenCL and OpenGL Compatibility Pack for Windows 10 on ARM OpenCL and OpenGL mapping layers to DirectX 12 OpenCL™ and OpenGL® Compatibility Pack in the Microsoft Store

See OpenCLon12 repo and the D3D12 driver in Mesa3d. This component also uses Clang/LLVM and libclc, along with Khronos’ SPIRV-LLVM-Translator and SPIRV-Tools.

D3D11on12 Maps graphics commands from D3D11 to D3D12. Note that D3D11On12 is not an implementation of the D3D11 API, but is instead an implementation of the D3D11 usermode DDI (device driver interface). D3D11On12 repo
D3D12 Translation Layer Helper library for translating graphics concepts and commands from a D3D11-style domain to a D3D12-style domain. D3D12TranslationLayer repo
ANGLE Abstraction layers allowing WebGL and other OpenGL ES content to run on DirectX 9 and 11 Google’s ANGLE repo
