Projekt Wine vydal verzi bal\u00ed\u010dku vkd3d 1.5 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 model\u016f shader\u016f 4 a 5 a libvkd3d-utils s funkcemi pro usnadn\u011bn\u00ed portov\u00e1n\u00ed aplikac\u00ed Direct3D 12, jako\u017e i sadu demonstra\u010dn\u00edch p\u0159\u00edklad\u016f, v\u010detn\u011b portu glxgears na Direct3D 12. K\u00f3d projektu je distribuov\u00e1n pod licenc\u00ed LGPLv2.1. <\/p>\n
Knihovna libvkd3d podporuje v\u011bt\u0161inu funkc\u00ed Direct3D 12, v\u010detn\u011b prost\u0159edk\u016f pro grafiku a v\u00fdpo\u010dty, front a seznam\u016f p\u0159\u00edkaz\u016f, popisova\u010d\u016f a popisova\u010dov\u00fdch hromad, ko\u0159enov\u00fdch signatur, neuspo\u0159\u00e1dan\u00e9ho p\u0159\u00edstupu, vzorkova\u010d\u016f, signatur p\u0159\u00edkaz\u016f, ko\u0159enov\u00fdch konstant, nep\u0159\u00edm\u00e9ho vykreslov\u00e1n\u00ed, metod Clear*() a Copy*(). <\/p>\n

Podporov\u00e1ny jsou vertexov\u00e9, pixelov\u00e9, tessela\u010dn\u00ed, v\u00fdpo\u010detn\u00ed a z\u00e1kladn\u00ed geometrick\u00e9 shadery, serializace a deserializace ko\u0159enov\u00e9 signatury.

Bylo provedeno mnoho vylep\u0161en\u00ed v kompil\u00e1toru shader\u016f v jazyce HLSL (High-Level Shader Language), kter\u00fd je k dispozici od DirectX 9.0. Byla vylep\u0161ena podpora objektov\u00fdch typ\u016f HLSL, jako jsou Texture2D, v struktur\u00e1ch a pol\u00edch, p\u0159id\u00e1na podpora vestav\u011bn\u00fdch funkc\u00ed dot(), ldexp() a lerp(), a pro modely shader\u016f 4 a 5 byla p\u0159id\u00e1na podpora logick\u00fdch oper\u00e1tor\u016f \u201eand\u201c, \u201eor\u201c a \u201enot\u201c, stejn\u011b jako mo\u017enost konverze boolean typ\u016f.\n
Byla implementov\u00e1na volba VKD3D_SHADER_COMPILE_OPTION_TYPED_UAV pro na\u010d\u00edt\u00e1n\u00ed neuspo\u0159\u00e1dan\u00e9ho p\u0159\u00edstupu (UAV) pro v\u00edcerozm\u011brn\u00e9 form\u00e1ty SPIR-V (DXGI_FORMAT). <\/ul>\n
