Ray tracing becomes a required option in GPU applications


RayTracing here refers to real-time RayTracing.
Real-time ray tracing has been very popular in the field of graphics computing in the past two years, even though ray tracing technology has been around for quite a long time.

Light pursuit is now recognized by the industry as a necessary technology for graphics computing, which can create a more real light-shadow relationship between 3D objects in the virtual graphics world, and make the picture more real visually.

In desktops, data centers and professional vision, the main thrust of ray tracing comes from Nvidia.

Both AMD and Intel's GPU products were actively followed up in 2021.

In the mobile world, it will be a little later because of the greedy computing requirements of ray tracing.

However, Imagination is ready for the implementation of ray tracing technology in the mobile field in 2020 in terms of IP; participants such as Arm and MediaTek are currently making pre-deployment in the market.

At the application level, it is needless to say that games and professional vision are important scenes in the early application of ray tracing.

But what ray tracing really represents is a kind of simulation and simulation technology in which the real world is mapped in the virtual graphics world.
Among the hot concepts in the past two years, both "digital twin" and "meta-universe" have put forward extremely high requirements for the physical simulation of the real world, including the simulation of physical properties such as light, particles, liquids, materials, springs, cables and so on.

A typical example of the application of ray tracing on digital twins is that Ericsson created the digital twins of a city with the help of Nvidia's Omniverse.
The virtual city has physical accuracy in buildings, vegetation, leaves and other materials, and realizes the accurate simulation of signal reflection intensity.
Using ray tracing technology, we can calculate and visualize the 5G signal quality of every point in the city, and finally design an efficient and reliable network.
The simulation and simulation technology represented by ray tracing will further drive the development of technologies and applications such as graphic world, digital twin, meta-universe and so on.
