Filters a point-cloud feature into one or more parts, output via separate ports, based on evaluating expressions.
Each point will only be filtered into a single point cloud. For example, if a point matches both the first and second expression, the point will only be placed in the point cloud for the first expression. An additional point cloud will be output that contains all the points that did not match any expression.
Note: Empty point clouds will not be output.
Input Ports
Input
This transformer accepts only point-cloud features.
Output Ports
You can specify an output port for each expression.
<Unfiltered>
Points that do not match any of the specified expressions are output via the <Unfiltered> port.
Parameters
Expression
An expression describing which points to include in a point cloud. Expressions are described in detail in the PointCloudExpressionEvaluator transformer.
Output Port
Specify the name of an output port for the point cloud.
Output Unfiltered Points
Whether to output a point cloud containing all the points that did not match any expression. When these points are not needed, setting this to No will improve performance.
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.
