三维模型的读取与体素化

简要说明3DS文件格式及模型数据读取方法,利用OpenGL库函数在VC++环境下分别对3DS文件中三维模型的顶点、边及面的坐标值和模型材质等进行读取,采用基于欧氏距离度量的体素化算法分别对读取到的顶点、边、面进行体素化,将以多边形网格表示的三维模型转化为6-邻域或26-邻域的体素模型,并对模型进行绘制.实验证明,程序具有较高的执行效率,能取得较好的效果.文章提出的体素模型有利于模型信号的规则化,方便模型特征信号的提取.

Reading and Voxelization of 3D Models

The file format and reading method of 3DS models are introduced.The material and the coordinates of vertex、edge、face of the 3DS model are read by using the OpenGL library functions in VC++.And a voxelization algorithm based on edclidean distance is adopted to convert 3D polygon mesh models to accurate 6-adjucent or 26-adjucent voxel models,which is helpful for the regularization of 3D models and is convenient to acquire external properties of 3D models.By using OpenGL,the reading and redrawing of 3D voxel models can be performed.Experiment results indicate that the algorithm is efficient and effective to produce voxelized models.
