L'azienda Crytek ha pubblicato un video che mostra i risultati dello sviluppo della nuova versione del proprio motore grafico CryEngine. La dimostrazione si chiama Neon Noir e presenta la funzionalit\u00e0 Total Illumination con il ray tracing in tempo reale.<\/p>\n

Una caratteristica chiave del ray tracing in tempo reale nel motore CryEngine 5.5 \u00e8 che non \u00e8 necessario avere nuclei RT specializzati o simili componenti di calcolo nella scheda video. Tutta l'elaborazione dei raggi avviene tramite le normali unit\u00e0 di calcolo, presenti in ogni scheda video, sia di AMD che di NVIDIA. A conferma di queste affermazioni, il video pubblicato con la dimostrazione Neon Noir \u00e8 stato creato utilizzando la scheda grafica 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 comunque alcune informazioni. Si segnala che nella demo, grazie al ray tracing, sono state visualizzate riflessioni e rifrazioni della luce, con riflessioni create anche per quegli oggetti che non si trovano in inquadratura. L'illuminazione globale della scena \u00e8 stata costruita utilizzando 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 di calcolo significativamente inferiore rispetto all'approccio offerto da NVIDIA con la sua tecnologia RTX. Di conseguenza, \u00e8 possibile generare immagini di alta qualit\u00e0 tramite ray tracing non solo con schede grafiche di fascia alta, ma anche di fascia media. Come si pu\u00f2 vedere, la Radeon RX Vega 56 offre una visualizzazione piuttosto attraente, sebbene sia una scheda grafica di livello medio, e il suo prezzo \u00e8 di soli 300 euro.<\/p>\n

\n \"Crytek <\/p>\n

Alla fine, Crytek sottolinea 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, mantenendo un alto livello di dettaglio. Sfortunatamente, la risoluzione e il frame rate della demo pubblicata non vengono specificati. Ma a vederlo, tutto sembra davvero molto promettente.<\/p>\n
