3D

Rasters

Creates an appearance style that can later be applied to a surface (using the AppearanceSetter, for instance).

Coordinate Space Terminology

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.

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

Configuration

Input Ports

A feature that contains either a raster or no geometry. If the input feature contains unsupported geometry, the unsupported geometry will be removed from the feature.

Output Ports

The set options that become attributes on that feature when it is sent out through the Output port.

Parameters

Appearance Name

A name that will help you remember what the appearance is for, such as "castle wall" or "house roof". Note that it does not have to be unique.

Attribute name string: fme_appearance_style_name

Diffuse Color

The most instinctive meaning of the color of an object, the essential color that is revealed under pure white light. It is perceived as the color of the object rather than a reflection of the light.

Attribute name string: fme_appearance_style_diffuse_color

Ambient Color

The color that the object reflects when illuminated by color from the surrounding medium rather than direct light.

Attribute name string: fme_appearance_style_ambient_color

Specular Color

The color of the light reflected from the object through specular reflection (the type of reflection that is characteristic of light reflected from a shiny surface).

Attribute name string: fme_appearance_style_specular_color

Emissive Color

Color of the light that the object is emitting itself.

Attribute name string: fme_appearance_style_emissive_color

Shininess

A value from 0.0 to 1.0 that specifies the shine of specular reflection, with 0.0 being completely dull and 1.0 extremely shiny.

Attribute name string: fme_appearance_style_shininess

Alpha

Specifies the transparency level of the appearance, with 0.0 being completely transparent and 1.0 completely opaque.

Attribute name string: fme_appearance_style_alpha

Texture Center u

Used to specify the origin of texture coordinate system. It is only used in conjunction with scaling and rotation.

Attribute name string: fme_texture_style_center_u

Texture Center v

Used to specify the origin of texture coordinate system. It is only used in conjunction with scaling and rotation.

Attribute name string: fme_texture_style_center_v

Texture Rotation Angle

Specifies the counter-clockwise rotation angle of the texture in degrees around the texture center (from a line parallel to the u-axis, passing through the texture center).

Attribute name string: fme_texture_style_rotation_angle

Texture u Shearing Factor

Used to specify the amount of shear along the u texture coordinate system axis, relative to the center.

Attribute name string: fme_texture_style_u_shearing_factor

Texture v Shearing Factor

Used to specify the amount of shear along the v texture coordinate system axis, relative to the center.

Attribute name string: fme_texture_style_v_shearing_factor

Texture u Scaling Factor

Used to specify the amount that the texture should be scaled along the u-axis.

Attribute name string: fme_texture_style_u_scaling_factor

Texture v Scaling Factor

Used to specify the amount that the texture should be scaled along the v-axis.

Attribute name string: fme_texture_style_v_scaling_factor

Texture u Offset

Used to specify the offset applied to the texture after all the other transformations are done.

Attribute name string: fme_texture_style_u_offset

Texture v Offset

Used to specify the offset applied to the texture after all the other transformations are done.

Attribute name string: fme_texture_style_v_offset

Texture Wrap Style

Only affects the area outside the 0 to 1 U and V range. Note that not all texture wrapping styles are supported by all output formats, in which case the texture wrapping style will be defaulted to a supported style individual writer.

None: means no texture wrapping style is given and behavior outside the 0 to 1 range is unspecified.

Repeat in U and V: will tile the texture in both directions.

Clamp in U and V: clamps both U and V to the 0 to 1 range and a constant boundary color will fill values outside this range.

Clamp in U and Repeat in V: clamps U to the 0 to 1 range and tiles in the V direction.

Repeat in U and Clamp in V: clamps V to the 0 to 1 range and tiles in the U direction.

Mirror: will mirror the texture in the U and V direction.

Border Fill: will use a constant border color to fill values outside the U, V 0 to 1 range.

Attribute name string: fme_texture_style_wrap

Texture Border Color

This parameter is used only with the Border Fill wrapping style, and is only supported by certain formats. It specifies the color to "bleed" into the space surrounding the texture raster.

Attribute name string: fme_texture_style_border_color

Editing Transformer Parameters

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, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

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.

Text Editor

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.

Arithmetic Editor

Conditional Values

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

Parameter Condition Definition Dialog

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.

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.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

  • Add a row
  • Remove a row
  • Move current row up one
  • Move current row down one
  • Move current row to top
  • Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

  • Cut a row - delete and copy to clipboard
  • Copy a row to the clipboard
  • Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.
