【摘要】 可视化交互技术在建模软件中占有举足轻重的地位。针对图形平台的交互系统,在OpenGL技术支持允许的范围内,实现了定位、视图控制、拾取及高亮3个反复使用的功能。功能的实现过程具有创新性,同时在效率和速度等方面有独特的特点。一套高效、灵活、方便的交互手段会为一个系统提供强有力的支持,而反复使用的核心的功能又为其他交互功能提供了基础服务。更多还原

【Abstract】 Interactive interface is an essential part of modeling software.This paper shows location,view control,selection and high lighting three core implementation with some OpenGL skill in a graphic platform,explains the innovations for realizing various functions,and also discusses about the efficiency and speed facets.A series of interactive interfaces which have efficient,flexible,and convenient capabilities provide strong supports to a system, and core implementation provides base services for other interactive function.更多还原
