Ray tracing (Ray Tracing) It's a technology that gives graphics a real look , The technology attempts to simulate how light works in the real world . Ray tracing does not create pre designed lighting for the game scene , It's tracking the path of simulated light , To be more exact , It's tracking millions of analog light / The photon . When objects move and interact with their properties , The light will be reflected back from the object . For example, light is reflected off a smooth green surface , Then the color of the light may change .

Because of the fundamental similarity between ray tracing and real life , So that it can render a realistic picture , But it's resource intensive , It takes a lot of computing power . Huawei Phoenix engine focuses on the core problem of ray tracing , Aiming at rendering faster 、 Better quality 、 It is easier to use several aspects to make technological breakthroughs one by one .

Huawei Phoenix engine self-developed multi-layer BVH Accelerate the structure 、 Multiforked tree Traversal Algorithm , Building efficiency 、Unbias Of RT-Core Algorithm base , Through the self-developed hybrid rendering pipeline based on Huawei hardware platform, the application of real-time ray tracing technology in mobile terminal is realized . meanwhile , In the sampling and noise reduction algorithm innovation and breakthrough , Give full play to neighborhood reuse 、 Time domain accumulation and other algorithm advantages , Achieve convergence efficiency 、 Signal to noise ratio and other indicators in the lead , Strong support for high realistic rendering 、 Quick preview and other rendering scenes . Last , The self-developed material system constructs a composite tree model based on material classification around energy conservation , Based on the standard model, a complete material instance library is extended , And support quick customization , It provides convenience and quality assurance for content creation . The above key technologies of ray tracing , Can be used to build the real world in the game , Achieve high quality architectural rendering and film rendering , Improve real-time preview and final imaging , Make the characters and pictures vivid , Get eye-catching visual effects .

some time , In addition to continuing to break through ray tracing , Huawei Phoenix engine will be committed to solving more graphics problems , Based on AI Content generation of , Data organization and rendering of super complex scene , Multi modal data visualization and other issues , Together with developers to bring users extraordinary picture quality enjoyment .
