简介

修改器是以非破坏性的方式影响对象的操作。使用修改器,您可以执行多次效果,要不然手动做会很很乏味的 (比如表面细分修改器)不会影响你的物体的基本几何形状。

They work by changing how an object is displayed and rendered, but not the geometry which you can edit directly. You can add several modifiers to a single object to form The Modifier Stack and Apply a modifier if you wish to make its changes permanent.

Modifiers menu.

修改器有四种类型:

修改类
The Modify group of modifiers includes tools similar to the Deform Modifiers (see below), but which do not directly affect the shape of the object; rather they affect some other data, such as vertex groups.
生成类
The Generate group of modifiers includes constructive tools that either change the general appearance of or automatically add new geometry to an object.
形变类
The Deform group of modifiers only changes the shape of an object without adding new geometry, and are available for meshes, and often texts, curves, surfaces and/or lattices.
模拟
The Simulate group of modifiers activates simulations. In most cases, these modifiers are automatically added to the modifiers stack whenever a Particle System or Physics simulation is enabled. Their only role is to define the place in the modifier stack used as base data by the tool they represent. Generally, the attributes of these modifiers are accessible in separate panels.

Panel layout (Subdivision Surface as an example).

Each modifier has been brought in from a different part of Blender, so each has its own unique settings and special considerations. However, each modifier's interface has the same basic components, see Fig. Panel layout (Subdivision Surface as an example)..

在顶部*菜单栏*。每一个图标代表了不同的修改器(从左到右):

Expand (down/right arrow icon)
通过折叠操作,使它只显示标题而不显示具体的选项。
Type
An icon as a quick visual reference of the modifier's type.
名称
每个对象每个修改器都有一个唯一的名称.两个(多个)修改器在一个物体上名称必须是唯一的。但是如果物体对像的不同修改器可以有相同的名称。默认的名称是基于修改器类型的名称。
Render (camera icon)
Toggles visibility of the modifier's effect in the render.
Show in viewport (eye icon)
Toggles visibility of the modifier's effect in the 3D View.
Show in Edit Mode (box icon)
Displays the modified geometry in Edit Mode, as well as the original geometry which you can edit.
Show on cage (triangle icon)
When enabled, the final modified geometry will be shown in Edit Mode and can be edited directly.
Move (up/down arrow icon)
Moves modifier up/down in the stack.
Delete X
用于删除修改器

Note

方块图标和三角网格图标不能使用或显示是由于修改器类型决定的。

在标题下方有两个按钮

应用
Makes the modifier "real" -- converts the object's geometry to match the applied modifier, and deletes the modifier.
复制
复制一个新的修改器到堆栈的底部。

Warning

应用修改,应用处于不在堆栈顶层的修改器,可能会产生意想不到的结果

在标题栏下面,所有修改器所拥有的选项会显示出来。

修改器堆栈

Modifiers are a series of non-destructive operations which can be applied on top of an object's geometry. They can be applied in just about any order the users chooses.

This kind of functionality is often referred to as a "modifier stack" and is also found in several other 3D applications.

In a modifier stack the order in which modifiers are applied has an effect on the result. Fortunately modifiers can be rearranged easily by clicking the convenient up and down arrow icons. For example, the image below shows Subdivision Surface and Mirror modifiers that have switched places.

Modifier Stack example.
../../_images/modeling_modifiers_generate_mirror_subsurf2.png

The Mirror modifier is the last item in the stack and the result looks like two surfaces.

../../_images/modeling_modifiers_generate_mirror_subsurf1.png

The Subdivision surface modifier is the last item in the stack and the result is a single merged surface.

Modifiers are calculated from top to bottom in the stack. In this example, the desired result (on right) is achieved by first mirroring the object, and then calculating the subdivision surface.

Example

../../_images/modeling_modifiers_introduction_stack-example-3.png

In this example a simple subdivided cube has been transformed into a rather complex object using a stack of modifiers.
