OPPO recently displayed its ongoing support for developers in fields like mobile graphics, computer vision, ray tracing, graphics rendering, and artificial intelligence at the SIGGRAPH 2023 event, which is a big deal for computer graphics and tech worldwide. Attendees got to see demos of the newest tech using OPPO’s devices like the OPPO Find X6 Pro, OnePlus 11, and OPPO Pad 2.

Better Mobile Ray Tracing with Improved PhysRay Engine

OPPO has been working with others in the industry to make mobile ray tracing better. Back in 2021, they were among the first to make an open ray tracing solution for mobiles, called PhysRay Engine. Last year, they let global developers modify and share PhysRay Engine 1.0. They also introduced PhysRay Engine 2.0, which has better ray tracing, special OPPO ray tracing effects, a mix of rendering styles, and offline full path tracing.

For more realistic mobile games, camera filters, and virtual reality, OPPO has worked hard on improving the PhysRay Engine both in how it works inside the phone and how it’s controlled by software. With help from Qualcomm Technologies, the Snapdragon 8 Gen 2 boasts strong hardware-based mobile ray tracing. Real-time Ray tracing now works even better and cooler with an optimization method called ReSTIR DI.


Visitors tried out CampGuard 3.0, a shooting mobile game that uses the improved PhysRay Engine. The new version of the game looks even more real and clear compared to the older one. Things like characters, skies, and clouds reflect in mirrors and other surfaces just like they would with sunlight, making the graphics look even better. OPPO also showed off its Ray Tracing Denoiser which helps clean up the look of 3D ray-traced stuff in mobile games. It can make soft and detailed shadows, even if there isn’t a lot of light.


Thanks to the Snapdragon 8 Gen 2’s fast ray tracing, the optical effects of Matrix and Skyline wallpaper look really nice. Users can also see cool wallpaper effects made by the physics engine, which OPPO and Taichi Lang worked on together.


OPPO’s Mobile Deep Learning Super Sampling – Clearer Pictures, Less Power

They also showed Mobile Deep Learning Super Sampling (DLSS), which was mostly for PC games before since it needs a lot of power and good hardware. But OPPO found a way to do it in real-time on phones. They made a special AI model and tools to make images look better without using too much power.


This AI model takes many lower-quality images, figures out how they move, and uses that to make high-quality images. This lets mobile gamers see things in better quality without using up too much battery.

OPPO also talked about Stable Diffusion on Mobile and Style Transfer on Mobile, two cool apps that use their special tools. They also talked about the Global Rendering Launcher. This tool makes things on screens look cooler by playing with light and shadow.
