基于VRML的多晶体晶粒三维形貌仿真及可视化研究

根据模拟微观组织的Rappaz连续形核模型和晶粒的细胞生长法,对多晶体凝固过程中晶粒组织进行了三维建模。采用面向对象的计算机仿真技术,完成了晶粒的三维形貌仿真;并将由VC 6.0中生成的仿真结果自动转换为VRML2.0的场景文件;在浏览器中实现了三维仿真结果可视化。在PC机上实验表明,所构建的仿真模型较好地模拟了多晶体的三维形貌;从而为多晶体材料微观组织的研究提供一种三维数字化模型。

Study on 3D Simulation and Visualization of Polycrystalline Grain''''s Shape Based on VRML

D modeling of microstructures of polycrystalline grains in the process of solidification is implemented based on Rappaz Model and the method of Cellular Growth of the grain. By using object-oriented technique, 3D simulation of grain microstructure is finished. Then, the simulation results created in VC 6.0 are converted into the scene files of VRML2.0 automatically. In the browser, finally, the interactive 3D-visulization is realized. The experimental results on personal computer demonstrate that these models built above can effectively simulate polycrystalline grains?shapes. Therefore, it provided a 3D digital model for further studying microstructures of polycrystalline materials.
