三维虚拟地理环境中点状要素二维图标表示法研究

Representation by 2D Symbols of Points Information in 3D Display Environment

结合三维虚拟地理环境中信息表达的特点,提出了在三维虚拟地理环境中利用二维图标的方式表现点状要素信息,以寻求一种全新的三维虚拟地理环境点状要素信息表达的解决方案,使用户可以在最短时间内形成对点状要素信息的总体把握与正确认识,提高了用户对场景的认知效率与深度。

Taking the terse and clear expression of 2D Symbols of Points information into account,based on the feature of 3D scene information expression,we put forward the method use the 2D symbols represented scene of Points information,expect it to the all new representation 2D Symbols of Points Information in 3D Display Environment.They can quickly achieve comprehensive and correct cognition.This method improves users＇ cognition efficiency and cognition depth.
