Projekt Wine zve\u0159ejnil vyd\u00e1n\u00ed bal\u00ed\u010dku vkd3d 1.11 s implementac\u00ed Direct3D 12, kter\u00e1 funguje prost\u0159ednictv\u00edm p\u0159ekladu vol\u00e1n\u00ed do grafick\u00e9ho API Vulkan. Sou\u010d\u00e1st\u00ed bal\u00ed\u010dku jsou knihovny libvkd3d s implementac\u00ed Direct3D 12, libvkd3d-shader s p\u0159eklada\u010dem shader\u016f modelu 4 a 5 a libvkd3d-utils s funkcemi pro usnadn\u011bn\u00ed portov\u00e1n\u00ed aplikac\u00ed Direct3D 12, stejn\u011b jako sada 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 prost\u0159edk\u016f pro grafiku a v\u00fdpo\u010dty, front, seznam\u016f p\u0159\u00edkaz\u016f, descriptor\u016f a deskriptor\u016f haldy, 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 vykreslov\u00e1n\u00ed, metod Clear*() a Copy*(). V libvkd3d-shader je implementov\u00e1no p\u0159eklad bytecode model\u016f 4 a 5 shader\u016f do mezivrstvy SPIR-V. Podporov\u00e1ny jsou vertexov\u00e9, pixelov\u00e9, tesselace, v\u00fdpo\u010detn\u00ed a jednoduch\u00e9 geometrick\u00e9 shadery, serializace a deserializace ko\u0159enov\u00e9ho podpisu.

Byla p\u0159id\u00e1na po\u010d\u00e1te\u010dn\u00ed podpora kompilace star\u00e9ho bytecode Direct3D do mezivrstvy shader\u016f SPIR-V.\n
Do kompil\u00e1toru HLSL byla p\u0159id\u00e1na po\u010d\u00e1te\u010dn\u00ed podpora pro kompilaci efektov\u00fdch profil\u016f Direct3D («fx_2_0», «fx_4_0», «fx_4_1» a «fx_5_0»).\n
