目前已有的FLAC~(3D)的实体建模方法基本上可以分为3类:通过FLAC~(3D)的内置网格生成器建立实体模型;通过Itasca公司开发的Kubrix网格生成器建立模型;通过第三方软件生成实体模型后导入FLAC~(3D).根据所划分的这3种类型的方法对现有的实体建模方法作了归纳与介绍,对各类方法的基本原理、应用情况和优缺点等进行了详述;并对这3种FLAC~(3D)实体建模方法进行了对比和总结. At present, the FLAC 3D solid modeling methods can be basically divided into three types: the solid model is built by the built-in grid generator of FLAC ~ (3D); the model is built by the Kubrix grid generator developed by Itasca Corporation ; Third-party software is used to generate the solid model and then imported into FLAC ~ (3D) .According to the three types of methods, the existing solid modeling methods are summarized and introduced. The basic principle and application of each method And advantages and disadvantages of these three kinds of FLAC 3D solid modeling methods were compared and summarized.
