【摘要】 基于对目前图形绘制引擎的特点的分析,针对目前图形绘制引擎应用中的突出问题,给出一种新的绘制引擎体系结构SREA,并在此基础上讨论了基于场景图的扩展机制、基于回调的扩展机制、Shader渲染框架以及基于IO管理器的模型读取组件扩展机制这四类扩展机制。通过这些机制,应用开发者可以快速方便的对于图形绘制引擎的绘制对象描述能力和绘制能力进行扩展,引入现有模型读取组件对于不同格式的模型进行读取,提高开发效率。更多还原

【Abstract】 Based on analysis about the feature of current rendering engine, four kinds of scalability mechanism were given based on a typical architecture for rendering engine to solve critical problems of application. Application developers are able to extend engine by such mechanisms easily and quickly in different aspects, so that they enhance the capability of description and rendering of engine, and the models with different formats are able to be read in.更多还原
