Sets the front and/or back appearance style(s) of specified geometries to be identical to a specific source geometry.如果您已经有一个具有外表的几何，则这很有用，所以要在其他几何形状上复制。
You can set appearances on allSurfacesand most geometry types that are, or can contain, Surfaces.
If you do not want to use the texture coordinates already present, you can also (at the same time) use the option to generate the texture coordinates of the affected surfaces.
Note: ">不te:当功能通过此变压器并将其出现设置时，它们不会简单地具有与源相同的属性的外观，但实际上它们将共享相同的奇异外观定义。

输入端口
Requestor
包含一些几何体的功能，可以设置外观。
Supplier
用作源的外观是从发送到此端口发送到此端口的每个组的第一个功能。
Output Ports
Output
所有输入Requestorfeatures are output whether or not anything was changed.
坐标空间术语
In order to reduce confusion between the real coordinate space of the surface and the texture coordinate space, this transformer uses "u" and "v" instead of "x" and "y" when referencing the latter. Note that this is also reflected in the parameter names.
Parameters
Group Processing
通过...分组
请注意，只有第一个Supplierfeature will be used in each "Group By" group.
通过...分组Mode
Process At End (Blocking)：这是默认行为。只有在存在所有输入时，处理将在此变换器中发生。
组更改时的过程（高级）: This transformer will process input groups in order. Changes of the value of the Group By parameter on the input stream will trigger processing on the currently accumulating group. This may improve overall speed (particularly with multiple, equally-sized groups), but could cause undesired behavior if input groups are not truly ordered.
考虑使用通过...分组
使用两种典型的原因组更改时的过程（高级）. The first is incoming data that is intended to be processed in groups (and is already so ordered). In this case, the structure dictates Group By usage - not performance considerations.
The second possible reason is potential performance gains.
最有可能在已经对数据进行排序的（或使用A读取SQL ORDER BY声明）由于FME需要更少的工作。如果数据需求排序，则可以在工作区中排序（尽管添加的处理开销可能会否定任何增益）。
Sorting becomes more difficult according to the number of data streams. Multiple streams of data could be almost impossible to sort into the correct order, since all features matching a通过...分组value need to arrive before any features (of any feature type or dataset) belonging to the next group. In this case, using通过...分组和Process At End (Blocking)可能是等同和更简单的方法。
Note: ">不te:Multiple feature types and features from multiple datasets will not generally naturally occur in the correct order.
As with many scenarios, testing different approaches in your workspace with your data is the only definitive way to identify performance gains.
几何部分选择
供应商几何XQuery.
此过滤器用于指示哪个部分Supplier几何将用作源外观样式。同样，如果多个几何部分匹配供应商几何XQuery.过滤器，第一个几何部件用作外观样式的源。
供应商：出庭
您可以指定的哪一边Supplier应该检索源外观样式的几何。
前面：纹理将从几何形状的前侧检索。
背面：纹理将从几何形状的前侧检索。
Requestor Geometry XQuery
This filter is used to indicate onto which part on theRequestorgeometry the Appearance Style is to be applied. The appearance is only directly set on the geometries which are specified through theRequestor Geometry XQueryselection. However, because appearances may be inherited further down a geometry hierarchy, setting an appearance directly at one level may have an effect further down a geometry hierarchy as well. Texture coordinates are therefore calculated, if necessary, on every geometry part that is affected by the setting of this appearance.
请求者：设置外观
您可以指定的哪一边Supplier应该检索源外观样式的几何。
前面：纹理将仅应用于几何形状的前侧。
背面：纹理将仅应用于几何形状的前侧。
Front and Back Sides:纹理将应用于几何形状的两侧。
Texture Coordinate Generation Parameters
Use Existing Texture Coordinates
当设置具有光栅纹理的外观时，受影响的几何形状的每个部分都需要纹理坐标。当此参数是不，始终针对由正在设置的外观影响的几何形状的每个部分计算新的纹理坐标。当此参数是是的，新的纹理坐标仅计算在尚未存在的几何形状的受影响部分上。现有的纹理坐标保持不变。
纹理映射类型
此参数指定如何在外观样式中定义的纹理将映射到曲面上。这仅适用于具有光栅图像的纹理。
Surface Normal:The textures are projected onto the surfaces along their normals. For composite surfaces and meshes, each of the child parts will be treated separately, since the parts can have different normals.
从顶视图：纹理沿着单个正常 - 垂直于X-y平面的一个正常的纹理投射到表面上。在该模式中，在施加纹理坐标时，复合表面被认为是单个几何形状。
你起源偏移
您可以使用此参数指定如何在U方向上移动纹理。
v Origin Offset
您可以使用此参数指定纹理如何在V方向上移位。
Texture u Repeat Factor
纹理U重复因子可用于指定纹理在行中重复的次数。
纹理V重复因子
纹理V重复因子can be used to specify the number of times the texture is repeated in columns.
编辑变换器参数
使用一组菜单选项，可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能，例如高级编辑器和算术编辑器。要访问这些选项的菜单，请单击
除适用的参数旁边。有关更多信息，请参阅Transformer Parameter Menu Options.
定义值
有几种方法可以在变压器中定义使用的值。最简单的是简单地输入值或字符串，其可以包括各种类型的函数，例如属性引用，数学和字符串函数和工作区参数。有许多工具和快捷方式可以帮助构造值的值，通常可以从与值字段相邻的下拉上下文菜单中提供。
如何设置参数值
使用文本编辑器
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
使用算术编辑器
算术编辑器提供了一种方便的方法来构建来自各种数据源的数学表达式，例如属性，参数和特征函数，其中结果直接在参数内使用。
Conditional Values
根据通过或失败的一个或多个测试条件设置值。
内容
Expressions and strings can include a number of functions, characters, parameters, and more.
设置值 - 无论是否直接在参数中输入或使用其中一个编辑器和包含字符串的表达式都是构造的，都会评估这些函数的字符串和表达式。因此，这些函数的名称（以@ <function_name.>) should not be used as literal string values.
内容类型

| 两个编辑器都有数学函数。 | |
| 日期/时间函数 | Date and time functions are available in the Text Editor. |
