基于VxWorks的OpenGL图形界面开发

Development of OpenGL Graphic Interface Based on VxWorks

提出一种基于VxWorks的OpenGL图形界面开发方法。研究VxWorks下的OpenGL图形解决方案及汉字生成的基本原理,提取字符的点阵信息生成点阵字体,使用FreeType产生矢量字体。将字体以OpenGL的方式绘制在图形中,实现基于VxWorks的中文图形界面。应用结果表明,该方法具有可行性和实用性。

This paper proposes a development method of OpenGL graphic interface based on VxWorks graphic solutions of OpenGL and the principle of displaying Chinese character is studied to realize the Chinese graphic interface based on VxWorks. The dot matrix that describes the Chinese character is picked out to create raster font, and the vector font is created by using the solution of FreeType. Through drawing the font on the graphic based on OpenGL, the Chinese graphic interface is realized. Application result shows the feasibility and availability of this method.
