List of Transformers

You are here: Surfaces AppearanceJoiner

AppearanceJoiner

Sets the front and/or back appearance style(s) of specified geometries to be identical to a specific source geometry. This is useful if you already have a geometry that has an appearance that you’d like to duplicate on other geometries.

您可以在所有内容设置外观Surfacesand 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:When features pass through this transformer and have their appearances set, they will not simply have appearances with identical properties to the source, but they will in fact be sharing the same singular appearance definition.

For more information on appearance support in FME, see外表.

输入端口

ClosedRequestor

包含一些几何体的功能，可以设置外观。

ClosedSupplier

The appearance to be used as the source is taken from the first feature from each group sent into this port.

Output Ports

ClosedOutput

所有输入Requestorfeatures are output whether or not anything was changed.

坐标空间术语

为了减少表面的真实坐标空间与纹理坐标空间之间的困惑，当引用后者时，该变压器使用“u”和“v”而不是“x”和“y”。请注意，这也反映在参数名称中。

Parameters

Transformer

Closed通过...分组

Note that only the firstSupplierfeature will be used in each "Group By" group.

Closed并行处理水平

Note:How parallel processing works with FME: seeAbout Parallel Processingfor detailed information.

This parameter determines whether or not the transformer should perform the work across parallel processes. If it is enabled, a process will be launched for each group specified by the通过...分组范围。

并行处理水平s

Parameter Number of Processes
没有平行 1
最小 coresThe processor, or CPU, is the physical part of the computer that performs mathematical calculations. It is the most important part of a computer system. Traditional processors have only one core on the processor, meaning that at any given time, only one set of calculations is being performed. If a processor is dual-core, this means the single chip contains hardware for two processors, now called cores to distinguish them from the single chip, running simultaneously, side by side.

缓和 exact number of cores
挑衅的 cores x 1.5
Extreme 核心x 2

For example, on a quad-core machine, minimal parallelism will result in two simultaneous FME processes. Extreme parallelism on an 8-core machine would result in 16 simultaneous processes.

You can experiment with this feature and view the information in the Windows Task Manager and the Workbench Log window.

ClosedInput is Ordered by Group

是的：此变压器将按顺序处理输入组。改变价值通过...分组参数的输入流将触发批量processing on the currently accumulating group. This will improve overall speed if groups are large/complex, but could cause undesired behavior if input groups are not truly ordered.

No: This is the default behavior. Processing will only occur in this transformer once all input is present.

几何部分选择

ClosedSupplier Geometry XQuery

This filter is used to indicate which part on theSuppliergeometry is to be used as the source Appearance Style. As well, if more than one Geometry Part match theSupplier Geometry XQuery过滤器，第一个几何部件用作外观样式的源。

Closed供应商：出庭

您可以指定哪一方Supplier应该检索源外观样式的几何。

前面：The texture will be retrieved from the front side of the geometry only.

Back Side:The texture will be retrieved from the front side of the geometry only.

Closed请求者几何XQuery.

该过滤器用于表示在哪个部分Requestorgeometry the Appearance Style is to be applied. The appearance is only directly set on the geometries which are specified through the请求者几何XQuery.选择。但是，因为可以在几何层次结构上进一步继承外观，所以直接在一个级别设置外观可能具有进一步下降几何层级的效果。因此，如有必要，纹理坐标在每个几何部分上计算受此外观的设置影响。

ClosedRequestor: Set Appearance On

您可以指定哪一方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。

Back Side: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

Closed使用现有纹理坐标

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No, new texture coordinates are always calculated for each part of the geometry that is affected by the appearance which is being set. When this parameter is是的, new texture coordinates are only calculated on the affected parts of the geometry where they do not already exist. Existing texture coordinates are left unchanged.

Closed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.

From Top View: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。

Closedu Origin Offset

您可以使用此参数指定如何在U方向上移动纹理。

Closedv Origin Offset

您可以使用此参数指定纹理如何在V方向上移位。

ClosedTexture u Repeat Factor

Texture u Repeat Factor can be used to specify the number of times the texture is repeated in rows.

ClosedTexture v Repeat Factor

Texture v Repeat Factor can be used to specify the number of times the texture is repeated in columns.

编辑变压器参数

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, clickbeside the applicable parameter. For more information, see变换器参数菜单选项.
