Problems solved by technology

However, when the rendering is completely undertaken by the server, a large amount of data needs to be transmitted to the mobile terminal, which puts forward high requirements on bandwidth. In practical applications, the rendered data cannot be transmitted to the mobile terminal in time due to transmission speed limitations. seriously affect the user experience

Embodiment Construction

[0036] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0037] Such as figure 1 As shown, the present invention provides a mobile device-based 3D model hybrid rendering system, allowing the client and the server to undertake a part of the rendering work, the server performs simplified calculation of data, and the mobile device as the client adopts

[0038] OpenGL ES does the rest of the rendering steps.

[0039] The system structure includes two parts: server and client. The server runs on a high-performance computer, and its main function is to read the 3D original model from the file, use the improved algorithm based on the quadratic error measurement to perform simplified calculation on the model (see below for th...

Abstract

The invention provides a 3D model hybrid rendering system and method based on a mobile device. The system includes a server and a client. The server is used for reading 3D data from a file, simplifying the 3D data and transmitting the 3D data to the client. The client is used for reorganizing the data and then rendering and displaying a 3D model using OpenGL ES. The client and the server communicate based on a TCP / IP mode, and transmission is filtered in a character stream mode. The method includes the following steps: the server reads a 3D model file, and analyzes and stores the 3D model file, the server simplifies and stores data; the server is connected with the client, and sends the data to the client; and the client reorganizes the data, and then renders and displays a 3D model usingOpenGL ES. A client-server mode is employed in the method. Complex computing operation is carried out on the server, and the mobile device is only responsible for the lighter rendering work. Therefore, the rendering speed and overall rendering efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of computer graphics processing, and relates to a three-dimensional visualization rendering technology, and more specifically, relates to a mobile device-based three-dimensional model hybrid rendering system and a rendering method. Background technique [0002] 3D visualization technology has always been a research hotspot in the industry, and mobile device technology is also developing, which promotes the emergence of visualization software based on mobile platforms. In recent years, many relatively mature 3D visualization platforms have emerged at home and abroad, such as ArcGIS, Skyline, Super Map, Imagine Virtual GIS, CityMaker, etc. But on the mobile side, 3D visualization research is relatively dependent on the platform. [0003] Due to the limitations of hardware conditions such as computing speed and memory and the requirements of interactivity, it is difficult for the mobile terminal to render comp...
