La societ\u00e0 Crytek ha pubblicato un video che mostra i risultati dello sviluppo della nuova versione del proprio motore di gioco CryEngine. La dimostrazione si chiama Neon Noir e mostra il funzionamento della funzione Total Illumination con il ray tracing in tempo reale.<\/p>\n

Una delle caratteristiche principali del ray tracing in tempo reale con il motore CryEngine 5.5 \u00e8 che non \u00e8 necessario avere core RT specializzati o simili unit\u00e0 di calcolo sulla scheda grafica. Tutta l'elaborazione dei raggi avviene tramite i normali blocchi di calcolo che sono presenti su ogni scheda grafica, sia essa AMD che NVIDIA. A conferma di quanto detto, il video pubblicato che dimostra Neon Noir \u00e8 stato creato con l'acceleratore grafico Radeon RX Vega 56. Tra l'altro, il ray tracing in CryEngine 5.5 funziona con qualsiasi API, sia essa DirectX 12 o Vulkan.<\/p>\n

\"Crytek <\/p>\n

Gli sviluppatori non rivelano tutti i dettagli, ma condividono alcune informazioni. Si segnala che nella dimostrazione il ray tracing ha visualizzato riflessi e rifrazione della luce, con i riflessi costruiti anche per quegli oggetti non visibili nel fotogramma. L'illuminazione globale della scena \u00e8 stata realizzata tramite un sistema SVOGI basato su voxel. Questo approccio ricorda in parte l'implementazione del ray tracing in Battlefield V.<\/p>\n

\"Crytek <\/p>\n

Il ray tracing basato su voxel richiede una potenza computazionale significativamente inferiore rispetto all'approccio offerto da NVIDIA con la sua tecnologia RTX. Di conseguenza, anche schede grafiche di fascia media possono generare immagini di alta qualit\u00e0 utilizzando il ray tracing. Come si vede, la stessa Radeon RX Vega 56 fornisce una visualizzazione piuttosto attraente, nonostante appartenga alle schede grafiche di fascia media, e il suo prezzo \u00e8 di soli 300 euro.<\/p>\n

Alla fine Crytek osserva che la funzione sperimentale di ray tracing implementata semplifica il rendering in tempo reale di scene e animazioni con riflessi e rifrazione della luce corretti a un alto livello di dettaglio. Purtroppo, la risoluzione e la frequenza dei fotogrammi della dimostrazione pubblicata non sono specificate. Ma visivamente tutto appare piuttosto soddisfacente.<\/p>\n
