SharedItemIDSetter

Each input feature should contain the geometries to set Shared Object IDs on, as well as the IDs to use, stored as traits or attributes.

All input Geometry features that have had Shared Object IDs set.

Input features where no geometry part matches the Geometry XQuery.

Input features that could not have a Shared Object ID set.

This parameter specifies whether to limit setting to only Appearances, Textures, Rasters, or Geometry Definitions.

You can specify the side of the geometry on which to set Appearances, Textures, or Rasters.

Front Side: The ID will be applied to the front side of the geometry part only.

Back Side: The ID will be applied to the back side of the geometry part only.

Front and Back Sides: The ID will be applied to both sides of the geometry part.

Use this parameter if you want to isolate only a portion of the geometry passed in to the transformer. If no criteria are specified, the action will apply to the entire geometry at all levels.

Selection can be based on structural location, geometry name, type, appearance information, traits, trait storage types, or definition reference. The syntax used is a restricted set of XQuery, where the return clause is fixed.

The basic Geometry XQuery dialog allows you to construct simple selection queries by automatically writing the necessary query based on specified test clauses. Clicking the Switch to Advanced button opens the Advanced Editor, which allows you to type a query free-form, for more expressive queries.

Note: Once you switch to Advanced mode, you will have to clear all parameters before you can return to Basic mode.

A hierarchical geometry is represented as nodes of type geometry, with attributes containing information about traits, type, and name for each geometry.

This parameter specifies whether to retrieve Shared Item IDs from attributes or traits.

The name of the attribute from which to retrieve Shared Item IDs.

The name of the trait from which to retrieve Shared Item IDs.

When an appearance with a raster texture is set, each part of the Geometry that is affected will also require texture coordinates. When this parameter is 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 Yes, 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.

This parameter specifies how the texture defined in an appearance style will be mapped onto the surface. This is only applicable to textures which have raster images.

• 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: The textures are projected onto the surfaces along a single normal – one that is perpendicular to the x-y plane. In this mode, a composite surface is considered as one single geometry when the texture coordinates are applied.
• Top Down Georeferenced: The textures are projected onto the surfaces using coordinates calculated based on a single normal perpendicular to the x-y plane and raster georeferencing information.
• From Texture Coordinate Generation Parameters Attribute: The textures are projected onto the surfaces using information stored in the fme_appearance_texture_gen_info attribute. This attribute can be generated by the SharedItemRetriever or AppearanceExtractor.

You can specify how the texture is shifted in the u direction with this parameter.

You can specify how the texture is shifted in the v direction with this parameter.

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

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

Using the Text Editor

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.

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

Content Types

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.
Math Functions	Math functions are available in both editors.
Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters	Create your own editable parameters.

Note: Not all tools are available in all transformers.
