| 摘 要： | 提出了一个语义环境模型,模型可分为3个层次:几何层、语义层和应用层。以虚拟环境三维几何模型和环境语义信息表为基础,结合虚拟角色自身的特征信息,生成完全面向该虚拟角色的环境语义信息。并将相关虚拟物体语义信息映射到环境模型上,把环境语义信息作为虚拟人路径规划的重要因素引入改进的规划算法,进而针对不同的障碍物和虚拟人进行路径规划。实验结果表明,语义环境模型为虚拟人提供了环境交互信息,提高了虚拟人的仿真度。

| Abstract: | A semantic environment model is presented,which includes three-tier framework: a geometric level,a semantic level and an application level.Based on the 3D model of whole virtual environment and environment semantics list,some special information about virtual human are considered to generate object semantics for the same virtual human.After that,those object semantics are mapped on environment model.Then taking environmental semantics as an important element,it is put into updated planning algorithm for dif... |
