Dans le cadre du projet VKHR<\/a><\/noindex> (Vulkan Hair Renderer) soutenu par les entreprises AMD et RTG Game Engineering, d\u00e9veloppe un syst\u00e8me de rendu r\u00e9aliste des cheveux, \u00e9crit en utilisant l'API graphique Vulkan. Le syst\u00e8me prend en charge le rendu en temps r\u00e9el lors de la mod\u00e9lisation de coiffures compos\u00e9es de centaines de milliers de m\u00e8ches et de millions de segments lin\u00e9aires. Gr\u00e2ce \u00e0 l'ajustement du niveau de d\u00e9tail, il est possible de varier entre performance et qualit\u00e9 de rendu. Il supporte la visualisation de diff\u00e9rents types de coiffures et de textures de cheveux. Le code du projet est \u00e9crit en C++17 et est fourni<\/a><\/noindex> sous licence MIT.<\/p>\n

La soci\u00e9t\u00e9 AMD a pr\u00e9c\u00e9demment travaill\u00e9 sur la technologie de rendu des cheveux dans le cadre du projet TressFX<\/a><\/noindex>, utilisant Direct3D. Dans le cadre du projet VKHR, la technologie mentionn\u00e9e a \u00e9t\u00e9 enti\u00e8rement r\u00e9\u00e9crite sur la base de Vulkan et \u00e9tendue par la simulation de diffusion de la lumi\u00e8re, de l'ombrage et de la transparence, r\u00e9alis\u00e9e \u00e0 l'aide de shaders GLSL. VKHR inclut un syst\u00e8me int\u00e9gr\u00e9 de tra\u00e7age de rayons, bas\u00e9 sur la biblioth\u00e8que Embree<\/noindex> d'Intel. Pour le lissage, une transformation lin\u00e9aire rapide est utilis\u00e9e, et pour cr\u00e9er l'effet de volume, un sch\u00e9ma de voxelisation rapide.
