\u00cen cadrul proiectului VKHR<\/a><\/noindex> (Vulkan Hair Renderer) cu suportul companiilor AMD \u0219i RTG Game Engineering, se dezvolt\u0103 un sistem de randare realist\u0103 a p\u0103rului, scris utiliz\u00e2nd API-ul grafic Vulkan. Sistemul suport\u0103 randarea \u00een timp real pentru modelarea coafurilor ce constau din sute de mii de fire \u0219i milioane de segmente liniare. Prin modificarea nivelului de detaliere, este posibil s\u0103 se varieze \u00eentre performan\u021b\u0103 \u0219i calitatea rand\u0103rii. Este suportat\u0103 vizualizarea diferitelor tipuri de coafuri \u0219i tipuri de l\u00e2n\u0103. Codul proiectului este scris \u00een C++17 \u0219i este livrat<\/a><\/noindex> sub licen\u021ba MIT.<\/p>\n

Compania AMD a lucrat anterior la tehnologia de randare a p\u0103rului \u00een cadrul proiectului TressFX<\/a><\/noindex>, utiliz\u00e2nd Direct3D. \u00cen cadrul proiectului VKHR, tehnologia men\u021bionat\u0103 a fost complet rescris\u0103 pe baza Vulkan \u0219i extins\u0103 cu simularea dispersiei luminii, arunc\u0103rii umbelor \u0219i transparen\u021bei, implementat\u0103 folosind shader-uri GLSL. VKHR include un sistem \u00eencorporat de trasare a razelor, bazat pe biblioteca Embree<\/noindex> de la Intel. Pentru netezire se folose\u0219te o transformare liniar\u0103 rapid\u0103, iar pentru crearea efectului de volum, o schem\u0103 rapid\u0103 de voxelizare. Modelele de coafuri sunt \u00eenc\u0103rcate \u00een formatul hair<\/a><\/noindex>.<\/p>\n
