Som en del af projektet VKHR<\/a><\/noindex> (Vulkan Hair Renderer) udvikles med st\u00f8tte fra AMD og RTG Game Engineering et system til realistisk rendering af h\u00e5r, skrevet med grafisk API Vulkan. Systemet underst\u00f8tter rendering i realtid ved modellering af frisurer best\u00e5ende af hundredtusinder af str\u00e5 og millioner af line\u00e6re segmenter. Gennem variation af detaljegraden er det muligt at balancere mellem ydeevne og renderingkvalitet. Der underst\u00f8ttes visualisering af forskellige typer frisurer og pels. Projektets kode er skrevet i C++17 og leveres<\/a><\/noindex> under MIT-licensen.<\/p>\n

AMD har tidligere arbejdet p\u00e5 teknologi til h\u00e5r rendering i forbindelse med projektet TressFX<\/a><\/noindex>, der brugte Direct3D. I projektet VKHR blev den n\u00e6vnte teknologi fuldst\u00e6ndig omskrevet baseret p\u00e5 Vulkan og udvidet med simulering af lysbrydning, skyggecasting og transparens, implementeret ved hj\u00e6lp af GLSL-shaders. VKHR inkluderer et indbygget ray tracing-system baseret p\u00e5 biblioteket Embree<\/noindex> fra Intel. For at udj\u00e6vne bruges hurtig line\u00e6r transformation, og for at skabe volumeneffekten anvendes en hurtig voxelering. Frisurer indl\u00e6ses i formatet hair<\/a><\/noindex>.<\/p>\n
