Projekt Wine vydal verzi bal\u00edku vkd3d 1.12 s implementac\u00ed Direct3D 12, kter\u00e1 funguje prost\u0159ednictv\u00edm p\u0159eklad\u016f vol\u00e1n\u00ed do grafick\u00e9ho API Vulkan. Bal\u00ed\u010dek obsahuje knihovny libvkd3d s implementac\u00ed Direct3D 12, libvkd3d-shader s p\u0159eklada\u010dem shader\u016f model\u016f 4 a 5 a libvkd3d-utils s funkcemi pro usnadn\u011bn\u00ed portov\u00e1n\u00ed aplikac\u00ed Direct3D 12, stejn\u011b jako sadu demonstra\u010dn\u00edch p\u0159\u00edklad\u016f, v\u010detn\u011b portu glxgears na Direct3D 12.

Knihovna libvkd3d podporuje v\u011bt\u0161inu funkc\u00ed Direct3D 12, v\u010detn\u011b n\u00e1stroj\u016f pro grafiku a v\u00fdpo\u010dty, front a seznam\u016f p\u0159\u00edkaz\u016f, popisova\u010d\u016f a popisova\u010d\u016f hromady, ko\u0159enov\u00fdch podpis\u016f, neuspo\u0159\u00e1dan\u00e9ho p\u0159\u00edstupu, Sampler-\u016f, podpis\u016f p\u0159\u00edkaz\u016f, ko\u0159enov\u00fdch konstant, nep\u0159\u00edm\u00e9ho (indirect) vykreslov\u00e1n\u00ed, metod Clear*() a Copy*(). V libvkd3d-shader byla implementov\u00e1na translace bajtk\u00f3du model\u016f shader\u016f do mezivrstv\u00e9ho form\u00e1tu SPIR-V. Podporov\u00e1ny jsou vrcholov\u00e9, pixelov\u00e9, tessela\u010dn\u00ed, v\u00fdpo\u010detn\u00ed a jednoduch\u00e9 geometrick\u00e9 shadery, serializace a deserializace ko\u0159enov\u00e9ho podpisu. Z instrukc\u00ed shaderu byly implementov\u00e1ny aritmetick\u00e9, atomov\u00e9 a bitov\u00e9 operace, oper\u00e1tory porovn\u00e1n\u00ed a \u0159\u00edzen\u00ed toku dat, instrukce sample, gather a load, operace neuspo\u0159\u00e1dan\u00e9ho p\u0159\u00edstupu (UAV, Unordered Access View). <\/p>\n

Do p\u0159eklada\u010de HLSL byla p\u0159id\u00e1na podpora p\u0159\u00edm\u00e9ho p\u0159eklad\u016f do assemblerov\u00e9ho k\u00f3du shader\u016f Direct3D a c\u00edlov\u00fdch typ\u016f SPIR-V.\n
V p\u0159eklada\u010di HLSL byla vylep\u0161ena podpora profil\u016f model\u016f shader\u016f 1, 2 a 3.\n
Pro HLSL byly implementov\u00e1ny vestav\u011bn\u00e9 funkce cosh(), determinant(), refract(), sinh() a tanh().\n
V libvkd3d byla p\u0159id\u00e1na podpora form\u00e1t\u016f DXGI_FORMAT_B5G6R5_UNORM, DXGI_FORMAT_B5G5R5A1_UNORM a DXGI_FORMAT_B4G4R4A4_UNORM, pokud jsou podporov\u00e1ny v existuj\u00edc\u00ed implementaci API Vulkan.\n
Byla p\u0159id\u00e1na podpora rozhran\u00ed ID3D12ShaderCacheSession a ID3D12Device9. Do rozhran\u00ed ID3D12Device8 byly p\u0159id\u00e1ny metody CreateCommittedResource2(), CreatePlacedResource1(), GetCopyableFootprints1() a GetResourceAllocationInfo2().\n
