A json-based graphic proxy implementation method

Abstract

The invention discloses a JSON-based graphics proxy implementation method. According to the characteristics of the drawing data and callback events transmitted between the functional components and the 2-3 graphics framework, respective proxies are established in the functional component side and the 2-3D graphics framework, and based on JSON flexibly agrees on the data format transmitted between components and frameworks. The invention shields the interface calls of the functional components and the framework through the graphic agent, and at the same time realizes the graphic interaction function of the two, decouples the functional components and the framework, reduces the influence of the functional components on the framework, improves the stability of the framework, and is more conducive to business Expansion of functional components.

Description

technical field [0001] The invention belongs to vehicle communication technology, and in particular relates to a method for implementing a JSON-based graphics agent. Background technique [0002] Large-scale system software based on the C / S mode usually performs a large amount of graphics display processing on the client side (C side). Plotting with terrain, elevation and various points, lines and surfaces to achieve professional business display function display. In addition, in order to facilitate the development and integration of various business scenarios, the "2D and 3D graphics integration framework + functional components" mode is usually adopted, that is, each component develops application functions based on the graphical interface provided by the integration framework, and then the integration framework loads and integrates on demand , each component completes the graphic interaction by calling the interface provided by the integration framework, specifically as ...

Problems solved by technology

[0004] However, in terms of interaction between components and the framework, the interactive interface of graphic display is still retained. With the continuous expansion of system functions, the shortcomings of this interaction method are gradually exposed: ①Although the components are low-coupled with the framework, the coupling based on the function interface To a certain extent, it will affect the stability of the framework. If a certain component runs abnormally, it will affect the framework and cause the framework to crash; ② With the continuous expansion of system functions, the number of components will continue to increase, and the client (C) will also It will inevitably become more and more bloated and more difficult to maintain
