What is real-time cloud rendering?

With the development of technology and industry segmentation, the new terminology is endless, for less familiar with the industry or technology encountered new terminology do not understand is very normal, the point amount of cloud small celery found in the cloud rendering, a lot of people for the real-time rendering there are still a lot of questions, and the question is more "What is real-time rendering". , about this problem has actually done a lot of description, simply put is the previous must be installed in the local computer program on the server, the user through ordinary computers, cell phones, tablets, VR glasses and other equipment can be used directly on the server program, a little bit similar to the more popular cloud desktop, but latency than the cloud desktop is much lower and can support more than cloud desktop software, the software can be used in a variety of types, including smart cities, digital media, and so on. There are more types of software to be supported, including UE4 and U3D commonly used in the smart city digital twin industry, and 3Dmax, revit, bently, CAD and so on in the construction industry. The server renders each frame of data into a picture, and then re-encodes it for transmission over the network to be presented on the terminal screen, and each frame of data, which is constantly changing, so that each frame is presented, is also constantly moving, and therefore is presented as a video stream on the terminal.

For users of this use and the previous computer habits are not very different, only need to open the browser URL can be, greatly reducing the use of the threshold. However, from a technical point of view it is much more complex. After all, to consider the optimization of each aspect of the process, the first thing is to ensure that the program can run properly, then the question is, Real-time rendering is to eat the CPU or graphics card?

Real-time rendering eats the graphics card, but this is not a real-time rendering program that has requirements for the graphics card, but rather requires real-time rendering of digital twins and other content that needs to be streamed, and its own operation requires the support of the graphics card in order to run properly. This is actually related to the program itself and the route of that technical solution. Running the program in a locally deployed solution actually requires a high-performance graphics card, except that the graphics card is installed on the local computer. Now the program is placed on the server side, so the same graphics card configuration is required on the server if the program is to run properly. But using real-time rendering is better than using a local one. First of all, not only computers, cell phones, tablets, and other devices can be used, but also the data is present on the server is safer and more convenient for operation and maintenance personnel to maintain later. In the case of graphics cards, you can also realize that a graphics card can support multiple users at the same time, providing the use of efficiency. And the server's computing power is generally better than a computer's, which is why real-time rendering will be faster.

Schematic of real-time cloud rendering

Real-time rendering refers to plotting three-dimensional data into two-dimensional bitmaps based on graphical algorithms and displaying those bitmaps in real time. It is essentially real-time computation and output of image data that requires rendering a picture and displaying it in a short period of time, as well as rendering and displaying the next picture. There is no way that this technology can be accomplished with just the CPU, it also relies on the graphics card to make it happen. So the CPU is not important, of course not, the CPU is also a very important constraint, because only it is normal operation plus the graphics card graphics computing power, can run through the whole process. So while real-time rendering eats at the graphics card, the CPU is also very important, and the two go hand in hand.

So how does the cloud fluidization software system work? Is it troublesome to use? To solve these questions, we first need to clarify what is cloud fluidization technology? In fact, simply a bit like remote desktop, but the principle of cloud fluidization technology and remote desktop is different, can support large, heavy all kinds of three-dimensional program directly in the cloud server. For users, there is no need to spend money on learning, and the operation is exactly the same as opening a web page or an app before, which is simple and convenient.

I. Steps to use

1, will have done the water conservancy digital twin model such as UE alive unity model installed in the server;

2, in the server to install the cloud streaming software system

3, to stream the water conservancy digital twin model such as UE alive unity model installed in the server. Add the storage address of the water twin model to be fluidized to the point volume cloud fluidization program to form a url link address that can be directly accessed by the user.

Point volume real-time cloud rendering system use flow

From the above, the cloud fluidization program is very simple to use, so that all parties do not need to pay attention to the inner how to fluidize, directly through the cloud fluidization program to complete with the help of the cloud computing power to run the program.
