Adds new components with constant values to a point cloud.

Jump to Configuration

Typical Uses

  • Adding standard or custom components to point cloud features to meet processing or format requirements.

How does it work?

The PointCloudComponentAdder receives point cloud features and adds one or more new components to them, with each new component set to a specified constant value. The components may be either standard named components that are not already in use on the feature, or user-specified components with non-standard names.

Each component definition consists of three parts - Component name, Data Type, and Value. A selection of data types is available, including various numeric types and strings. Values may be entered directly or obtained from an attribute or expression. The value will be applied as a constant value to all points in the point cloud feature.


Usage Notes

  • The PointCloudExpressionEvaluator can also add components in a similar fashion, however, it does not support string values.
  • To update the values of components that already exist on a point cloud, use the PointCloudExpressionEvaluator.
  • To set individual point component values, including values derived from expressions using existing point component values, use the PointCloudExpressionEvaluator.
  • To convert attributes and values to components when converting other data types to point clouds, use the Attributes to Preserve as Components parameter in the PointCloudCombiner.

Choosing a Point Cloud Transformer

FME has a selection of transformers for working specifically with point cloud data.

For information on point cloud geometry and properties, see Point Clouds (IFMEPointCloud).

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.

Dialog Options - Tables

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