Decodes a binary attribute containing encoded point clouds stored as Blobs, replacing the feature’s geometry with the decoded point cloud.

Jump to Configuration

Typical Uses

  • Restoring point clouds previously extracted into an attribute by the PointCloudExtractor, often used to store point clouds as Blobs in non-spatial databases.
  • Creating geometry from point clouds read with an AttributeFileReader transformer.

How does it work?

The PointCloudReplacer receives features of any geometry type (or no geometry) that have point clouds stored as Blob attribute of the feature, most often a result of having previously used the PointCloudExtractor to store them as Blob attributes to meet format or processing requirements.

The format of the encoded Blob point cloud must be provided. The attribute storing the Blob may be optionally removed after decoding and replacing the feature’s geometry with the point cloud. Removing the attribute reduces feature size and memory usage, and may improve performance.


Usage Notes

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.
