OnePlus has announced a technical partnership with Perfect World Games on ray tracing technology. The companies said that they have worked closely to bring the ray tracing technology to Tower of Fantasy in-game play on the OnePlus 11 5G.
Ray Tracing on Mobile Gaming
Ray tracing is a technology that enables dynamic in-game lighting, reflections, cross-physics illuminations and shadows, allowing for extreme environmental realism when gaming.
The OnePlus 11 5G is equipped with Snapdragon 8 Gen 2 mobile platform that supports hardware accelerated ray tracing technology, which provides the opportunity for OnePlus to work with Perfect World Games to fully explore the potential of ray tracing on mobile.
Ray Tracing in Open World MMORPG on Mobile
Compared to traditional MMORPG games, incorporating ray tracing in open-world games has significant technical challenges, especially on mobile platform. Perfect World Games said that it has developed techniques such as a distance-based dynamic object frame-updating mechanism and range-based ray tracing culling based on light source perspective, which enables players to experience real-time stable frames while enjoying ray tracing effects.
Additionally, for the open-world scenes in Tower of Fantasy, the ray tracing acceleration structures are further optimized through employing small object culling and view frustum culling based on camera frustum solid angle. By accurately simulating the propagation and interaction of light rays, players can immerse themselves in the Vera desert and experience the more realistic effect of flames from the surroundings and the hot sand underfoot.
Normally, open world MMORPG game experience is more immersive than traditional MMORPG game due to more realism detailed objects, and this experience is further elevated by ray tracing technology, said the company.
The introduction of mobile ray tracing technology also enables more accurate capturing of shadows and occlusion effects of objects in the distance and behind other objects, resulting in better visual performance compared to traditional rendering techniques.
Ray Tracing on the OnePlus 11 5G
The objective for this partnership is to improve the visual and performance experience on mobile device. To improve the graphics quality, engineers from OnePlus and Perfect World Games co-developed the Real-time Inline Ray Tracing Pipeline and a novel Fast Temporal Convergence Algorithm for Ambient Occlusion, specifically tailored to meet the demands of “Tower of Fantasy” by utilizing a forward rendering pipeline.
To cope with the demanding graphics computing power brought by ray tracing technology, the Spatiotemporal Oversampling is employed. The OnePlus 11 5G has 16 GB LPDDR5X RAM, 256GB UFS 4.0 storage, and the new Cryo-velocity VC Cooling System, so it can support the real-time rendering of mobile ray tracing on the graphics of Tower of Fantasy.
Demo at MWC 2023
OnePlus will showcase ray tracing enabled Tower of Fantasy at Hall 3, 3M10 at the MWC 2023 from February 27th to March 2nd.
Commenting on the partnership, Kinder Liu, OnePlus COO and Head of R&D, said:
We’re extremely thrilled to cooperate with Perfect World Games to showcase this industry-leading technology that shapes the future of mobile gaming experience on the OnePlus 11 5G. OnePlus is dedicated to providing the most immersive game experience to our users, and today we take this experience to a new level.
Dan Xu at Perfect World Games, said:
We’re excited to cooperate with OnePlus to apply this advanced technology that previously only be seen on PCs in mobile phone,” said “As a leading game developer, our mission is to bring the best experience to gamers, and ray tracing technology will dramatically transform the in-game experience.
