飞行显示器汉字显示典型问题及应对

Typical Problems about Chinese Display on Flight Display and Coping Strategies

针对飞行显示器软件开发中汉字显示问题,采用自行开发的基于OpenGL和FreeType的汉字显示引擎与IData、SCADE等常用开发工具集成,完成PC机上汉字显示的仿真;合适的汉字大小、颜色及描边等可实现汉字在各种情况下的可辨识;充分利用多级缓冲、相同几何体集中渲染、汉字分类等优化方法,实现了汉字的快速渲染。采取上述措施可解决飞行显示器软件开发中汉字显示相关问题。

To cope with the problems about Chinese display confronted in flight display software development,font engine based upon OpenGL and FreeType is used with IData,SCADE developing tools and so on.It fulfills Chinese simulation on PCs.By choosing appropriate size,color and haloing,Chinese characters can be easy to discern in all environments.The article introduces optimization strategies such as multi caching,like shapes grouping and character classification.These can speed up rendering of Chinese.Typical software problems about Chinese display on flight display can be solved using the methods presented in this article.
