Applies a point cloud’s scale, offset, or transformation matrix to it, recalculating component values and removing the transformation values.

Jump to Configuration

Typical Uses

  • Forcing the application of transformations such as scale, offset, rotate, and shear to meet format or processing requirements.
  • Creating point clouds compatible with processing, formats, or applications that cannot handle transformations.

How does it work?

The PointCloudTransformationApplier receives point cloud features and applies transformations that are already present on the point cloud, recalculating the affected component values and removing the transformation from the feature.

Scale and Offset may be stored on individual components, and are applied by selecting those components in the Apply Scale and Offset to Components list.

Other transformations, such as rotate and shear, will be handled with a Transformation Matrix, and are applied with the Apply Transformation Matrix parameter.

Applying a transformation is primarily done for compatibility with other processing and writers that cannot support the transformation natively.

For example, the LAS reader produces Int32 coordinates with a scale and offset. However, the POINTCLOUDXYZ writer cannot support component scale/offsets, so the transformation will be applied upon writing. The resulting coordinates will be Real64 with no transformation.

Note that processing and writers that cannot support transformations will apply them automatically, but this transformer can be used to manually apply the transformation if desired.


Usage Notes

  • This transformation does not create transformations - they must already be present on the point cloud. Transformations can be created with a number of other transformers, including the Affiner, 3DAffiner, Rotator, 3DRotator, Scaler, and Offsetter.

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.
