摘要
对可视化仿真中的三维建模技术进行了研究。从模型的实现途径入手,分析了各种建模方法的特点和应用领域,给出了建模方法的选择策略;对主流三维建模工具进行了深入探讨,给出了建模工具的应用策略;针对仿真对模型的管理和调用需求,分析了层次化建模的必要性;针对大量模型的异构问题,通过实践探索了几种主流三维格式到FLT格式的途径,给出了模型的归一化策略;最后对三维实体模型的建模流程进行了归纳,并演绎出具有一般意义的三维实体建模策略集,对可视化仿真中的三维实体建模具有了一定的参考价值。
Modeling technologies of three-dimensional（3D） in visual simulation were studied.Proceeding with the realization of models,the characteristics and application fields of varies modeling methods were analyzed,and the selection strategies were given.The mainstream 3D modeling tools were discussed in deeply and the application strategies of modeling tools were given.Aiming to the requirements of simulation models＇ management and calling,the necessity of hierarchical modeling was analyzed.Aiming to the heterogeneous problem of lots of models,several methods of formats transformation form 3D to FLT were realized through practice and exploration,and the normalization strategies of modeling were given.Finally,the 3D modeling process was induced,and a suit of 3D modeling strategies with general senses was deduced,which has a certain reference value for 3D modeling in visual simulation.
