specific Embodiment approach 1

[0060] Specific implementation mode one: the following combination Figure 1 to Figure 4 Illustrate the present embodiment, the method for designing the frame system of the full LCD car instrument graphic frame based on OpenGL ES described in the present embodiment, the method is realized by the following steps,

[0061] Step 1. Establish ACTOR structure;

[0062] The data field of the ACTOR structure consists of the following items:

[0063] [TypeFlag], indicating that the object is a graphic element or a container, the graphic element corresponds to a component displayed directly on the screen, and the container is used to hold other sub-graphic elements and sub-containers;

[0064] [next], store a pointer to the next ACTOR structure;

[0065] [ShowFlag], indicating whether the graphic element is finally displayed on the screen;

[0066] [VertexCoord], indicates the vertex coordinates of the graphics element;

[0067] [TextureCoord], indicates the texture coordinates of ...

Abstract

The invention discloses an OpenGL ES (open graphics library for embedded system)-based graphical framework system designing method for a pure liquid crystal automobile instrument panel, relates to a lightweight graphical framework system, and aims to solve the problem of high pure liquid crystal automobile instrument panel design cost caused by complex internal principle, high design difficulty and high hardware requirements of a conventional pure liquid crystal automobile instrument panel. According to the method, the design cost and code amount of a framework are reduced, and code maintenance and version upgrading are facilitated; the internal principle is simple, the graphical framework system is easy to design, a developer can flexibly achieve various expected effects on the basis of the framework, and an implementation method applied to each display component of the automobile instrument panel is designed; the bottom layer of the described graphical framework system is only dependent on an OpenGL ES which is transplanted to each operating system, so that the graphical framework system can be transplanted between different operating systems after slight modification, and the reusability and transplantability of the system is improved; the method is applied to the lightweight graphical framework system.

Description

technical field [0001] The present invention relates to a lightweight graphics framework system. Background technique [0002] Automobile instrumentation has a history of more than a century since its birth. With the continuous development of power electronics technology, automotive instrumentation has also undergone many major changes. According to the different working principles of automobile instrumentation, it can be roughly divided into three generations. The first generation of automotive instrumentation is a mechanical instrument that works based on mechanical force, that is, a mechanical movement watch; the second generation of automotive instrumentation is based on various sensors that convert non-electricity into electrical signals and become electrical instruments; the third type of automotive instrumentation The meter uses a stepping motor to control the rotation of the pointer. This is a networked and intelligent full-digital car meter. Most of the current au...
