地物仿真及交互可视化编辑工具的设计与实现

Design and Implement of Terrain &Object Simulation and Editing Visually Kit

地形是虚拟环境的承载体,地形建模也是综合自然环境建模的基础环节。综合自然环境建模的目的不仅是使地形等相关环境要素在虚拟环境中得到本征还原,更重要的是构筑人与虚拟环境的多层面交互通道。其中,对模型实施编辑及分析是交互的两个重要层面。论文基于此开发了地物仿真及交互式可视化编辑工具-----TEVS,以地形要素为代表,探索将环境要素建模、编辑与分析三者加以整合的技术方法。论文提出了人与虚拟环境交互行为的划分层次,从低层到高层依次为数据级、分析级和协同级。论文认为在综合自然环境下,原先处于分散,无序的环境要素模型应该被有序地组织,从而使其具有可控性及可编辑性,为最终实现人与虚拟环境有序和谐的交互奠定基础。

Terrain is the carrier of virtual environment, and it is also the groundwork of constructing model in Synthetic Natural Environment （SNE）. In SNE, the goal of modeling is not only restoring environment elements truly such as terrain but also constructing the multi-level interaction channels. Editing and analysis is an important level of the channel. In the guidance of this idea, a kit named TEVS was developed. At the same time, an approach for editing and analyzing the model was explored. A division of interaction behave levels between human and virtual environment was presented. From low to high, They are data level, analysis level and collaboration level in order The non-sequence environment elements should be organized sequentially and controllability in SNE. Human can implement the interaction with virtual environment sequentially and harmoniously on this base.
