1.几何（学）
geometry is the branch of mathematics concerned with the properties and relationships of lines, angles, curves, and shapes.
e.g. ...the very ordered way in which mathematics andgeometry describe nature.
数学和几何学极有条理的描述自然的方式
2.形状；外形；几何图形；几何结构
Thegeometry of an object is its shape or the relationship of its parts to each other.
e.g. They have tinkered with thegeometry of the car's nose.
他们对车头的外观进行了改进。
1. 几何体：但是折线的段数尽量多些,每层的点的数量最好一样多,把等高线用移动工具在高度方向上依次拖到相应的高度,也就是使等高线等高地排列,选择最底下一条,再在创建面板中创建几何体(geometry),几何体类型合成物体(Compounde Object),
2. geometry的意思
2. 几何形状：形状结点(shapes)定义了三维场景中物体的几何形状(geometry). 基本形状结点(primitive)是一些标准的积木块,它们是矩形体、圆锥体、球体等. 外表(appearance)结点描述了具有一定几何形状物体的外观,比如说色彩、纹理等等.
