简介

The creation of a 3D scene needs at least three key components: Models, materials and lights. In this part, the first of these is covered, that being modeling. Modeling is simply the art and science of creating a surface that either mimics the shape of a real-world object or expresses your imagination of abstract objects.

模式

Depending on the type of object you are trying to model, there are different types of modeling modes. Since modes are not specific to modeling they are covered in different parts of the manual.

建模时在模式之间切换很常见。某些工具可能可以在多个模式下使用，而其他工具则可能是专用于特定模式。

编辑模式

编辑模式是建模用到的主要模式。以下物体类型均可使用编辑模式：

• 网格

• 曲线

• 面

• 融球

• 文本对象

• 晶格

用户只能修改正在编辑的物体的网格。要修改其他物体，可以离开编辑模式，选择其他物体，并进入编辑模式，或使用 多物体编辑。
