At SIGGRAPH 2023, the top conference for computer graphics and interactive technologies globally, OPPO recently showed how it continues to assist and empower developers in mobile graphics, computer vision, ray tracing, graphics rendering, and artificial intelligence.Â
Visitors to the worldwide smartphone brand had their hands on demos of the newest innovations via its top products such as the OPPO Find X6 Pro, OnePlus 11, and OPPO Pad 2.Â
“OPPO has always been committed to promoting the development of mobile graphics and computer vision. Last year, we partnered with Qualcomm Technologies to truly bring about a hardware-based mobile ray tracing experience. Through the demos of our various technologies, we’d like to share our latest progress with the SIGGRAPH audience.” Chen Li, Head of Computing and Graphics Research Institute at OPPO statedÂ
Refined PhysRay Engine Brings More to Mobile Ray TracingÂ
It took the initiative in 2021 to establish PhysRay Engine, one of the industry’s first open ray tracing systems for mobile devices.Â
Last year, OPPO made PhysRay Engine 1.0 available for global developers to modify and redistribute, while also revealing its next stage in PhysRay Engine 2.0, which integrates advanced ray tracing capabilities, including OPPO-exclusive ray tracing effects, a mixed rendering pipeline, and offline full path tracing.Â
OPPO has pushed the limits of performance for more colorful, lifelike mobile games, photo filters, and even virtual reality scenarios by improving the PhysRay Engine at every step of the way on both the hardware and software levels.Â
Qualcomm Technologies, Inc. collaborated to make the newest Snapdragon 8 Gen 2 mobile platform feature sophisticated hardware-based mobile ray tracing. Furthermore, the real-time rendering impact of ray tracing has been enhanced even further with the advent of optimization methods such as ReSTIR DI.Â
Visitors to SIGGRAPH 2023 loved playing CampGuard 3.0, a shooter mobile game built on the enhanced PhysRay Engine. The revised version’s game sceneries are considerably more vivid and lifelike than their predecessor. The reflections of figures, sky, and clouds in mirrors and other surfaces may interact with sunlight, producing images that are even more spectacular.Â
The Ray Tracing Denoiser was also shown by OPPO. In 3D ray tracing applications, such as mobile games, a noise reduction technique can replicate smooth and detailed shadow effects even in low-light situations.Â
With the help of real-time, hardware-accelerated ray tracing powered by Snapdragon 8 Gen 2, the propagation, reflection, and refraction optical effects of Matrix and Skyline wallpaper are more vivid. Users may also enjoy the breathtaking visual effects of the wallpaper driven by the physics engine, a collaboration between OPPO and Taichi Lang. The silk-like wallpaper glides smoothly, while the fireworks blossom with genuine, real-life splendor.Â
OPPO Mobile Deep Learning Super Sampling – A Perfect Combination of High-Res Image and Low Power ConsumptionÂ
Mobile Deep Learning Super Sampling (DLSS) was also demonstrated, a technology that was previously limited to PC games due to the high computing power and high-end hardware required. However, OPPO found a way forward by utilizing real-time rendering via a self-developed, lightweight, ultra-high-resolution AI model and rendering pipeline with its inference engine, ShaderNN.Â
The AI model samples and produces several lower-resolution images with fewer pixels, then uses motion data and input from previous frames to generate more detailed, higher-resolution graphics, offering mobile gamers a high-quality gaming experience without worrying about battery usage.Â
OPPO has also released new apps powered by ShaderNN, such as Stable Diffusion on Mobile and Style Transfer on Mobile.Â
Moreover, OPPO showcased its Global Rendering Launcher for graphics rendering. Elements like as icons and numbers may produce an interplay of light and shadow across the screen by generating 2D layers to imitate propagation, reflection, and refraction effects.Â
