Tout le traitement des rayons s'effectue avec les blocs de calcul standard disponibles sur chaque carte graphique, qu'elle soit AMD ou NVIDIA. En attestent les vid\u00e9os publi\u00e9es, comme celle de d\u00e9monstration de Neon Noir, r\u00e9alis\u00e9e gr\u00e2ce au GPU Radeon RX Vega 56. D'ailleurs, le ray tracing dans CryEngine 5.5 fonctionne \u00e9galement avec n'importe quelle API, que ce soit DirectX 12 ou Vulkan.<\/p>\n<p> <img decoding=\"async\" alt=\"Crytek a d\u00e9montr\u00e9 le ray tracing en temps r\u00e9el sur Radeon RX Vega 56\" src=\"\/wp-content\/uploads\/2019\/03\/cf2b6f0a8bbd622522314fea3c6cb0ad.JPG\" style=\"display:block;margin: 0 auto;\" \/> <\/p>\n<p>Les d\u00e9veloppeurs ne r\u00e9v\u00e8lent pas tous les d\u00e9tails, mais partagent tout de m\u00eame quelques informations. Il est not\u00e9 que dans la d\u00e9monstration, le ray tracing a permis de visualiser des r\u00e9flexions et des r\u00e9fractions lumineuses, les r\u00e9flexions \u00e9tant g\u00e9n\u00e9r\u00e9es m\u00eame pour des objets hors champ. L'\u00e9clairage global de la sc\u00e8ne \u00e9tait construit \u00e0 l'aide d'un syst\u00e8me SVOGI bas\u00e9 sur des voxels. Cette approche rappelle en quelque sorte l'impl\u00e9mentation du ray tracing dans Battlefield V.<\/p>\n<p> <img decoding=\"async\" alt=\"Crytek a d\u00e9montr\u00e9 le ray tracing en temps r\u00e9el sur Radeon RX Vega 56\" src=\"\/wp-content\/uploads\/2019\/03\/f17dc5fd93718c6681ae8f50f1861f39.JPG\" style=\"display:block;margin: 0 auto;\" \/> <\/p>\n<p>Le ray tracing bas\u00e9 sur des voxels n\u00e9cessite beaucoup moins de puissance de calcul que l'approche propos\u00e9e par NVIDIA avec sa technologie RTX. Gr\u00e2ce \u00e0 cela, les cartes graphiques non seulement de haut de gamme mais aussi de milieu de gamme peuvent produire une image de qualit\u00e9 en utilisant le ray tracing. Comme on peut le voir, la Radeon RX Vega 56 offre une visualisation tr\u00e8s s\u00e9duisante, bien qu'elle appartienne aux cartes graphiques de milieu de gamme, et son prix n'est que de 300 euros.<\/p>\n<p><center><\/center><br \/>\n <img decoding=\"async\" alt=\"Crytek a d\u00e9montr\u00e9 le ray tracing en temps r\u00e9el sur Radeon RX Vega 56\" src=\"\/wp-content\/uploads\/2019\/03\/b0d8d0380faa2bd0bd064cb22e383f17.JPG\" style=\"display:block;margin: 0 auto;\" \/> <\/p>\n<p>\u00c0 la fin, Crytek note que la fonctionnalit\u00e9 exp\u00e9rimentale de ray tracing mise en \u0153uvre facilite le rendu en temps r\u00e9el des sc\u00e8nes et des animations avec des r\u00e9flexions correctes et des r\u00e9fractions lumineuses \u00e0 un haut niveau de d\u00e9tail.
