什么是几何建模内核?

几何建模内核是 CAD(计算机辅助设计)和其他建模软件中的三维建模组件。

任何 CAD 系统的核心都可以看作是几何内核或 "实体建模内核"--没有这个内核,就无法生成您在屏幕上看到的图像。



建模内核是用数学公式写成的,这些公式被转换成图形,就像网站的代码一样,可以显示真实世界的内容。创建三维模型,就其本质而言,需要使用内核来计算复杂的数学公式,即使是简单的图像也是如此。

几何建模内核的工作原理

简单来说,内核会为您完成所有繁重的工作。

例如,假设您想对一个对象执行操作,比如创建多个图层或生成曲线边缘等。使用“将此边缘变为曲线”或“添加图层”等基本命令,内核能够迅速而准确地执行这些指令。

当然,这只是能够执行特定功能的一种“几何”内核。

每个内核的功能取决于所设置的参数。同一类别的两个内核会以不同的方式解析相同的命令,从而产生不同的结果。

这里需要记住的重要一点是,内核就像工匠,每个工匠都有不同的专长,能够执行不同的任务。

所有内核并非相同:简单型与高级型

请不要误会,在CAD领域,即使是简单的命令也需要进行复杂的计算。

例如,如果您想在一个对象上打一个孔并计算两端的边缘,内核会执行这项任务。

总体来说,这是一条相当简单的指令。

几何内核只是冰山一角;其他类型的内核则允许您执行更高级的任务,如概念设计和详细设计。

精选几何建模内核软件


Spatial 的 Convergence Geometric Modeler (CGM) 是一款用于独立 CAM 和 CMM 软件的内核。它的一些最显著的应用案例包括:

  • 将 CATIA 插件转换为独立产品
  • 与其他多 CAD 环境的兼容性
  • 利用 CGM 的 InterOp 文件转换功能来防止设计错误,例如间隙和属性不匹配。

无论您从事增材制造、CAE 还是 CAM,Spatial CGM 都是满足您 3D 建模需求的强大工具和平台。

其他软件还包括 Parasolid、C3D 和 3D ACIS Modeler。
