    PointCloudSplitter

    Splits a single point cloud feature into multiple point cloud features, each having a homogeneous value for the point component that governs the split.

    Input Ports

    ClosedInput

    This transformer accepts only point cloud features.

    Output Ports

    ClosedSplit

    Multiple point-cloud features as specified by the Split By parameter.

    Parameters

    ClosedSplit By

    Specifies the component(s) on which the point cloud will be split. This may be any single component name, or one of the following special values:

    Color:The point cloud will be split on thecolor_red,color_green, andcolor_bluecomponents.

    First Return Only:One point cloud feature is output containing all the points whose return number is 1.

    Last Return Only:One point cloud feature is output containing all the points which represent the last return (that is, where the return number is equal to the number of returns).

    ClosedSplit Type

    Specifies whether to split by unique values or ranges. When splitting by unique values, one point cloud will be output for each unique value of the specified component found in the point cloud. When splitting by ranges, one point cloud will be output for each specified range of values, provided at least one point falls in the range.

    ClosedOutput Attribute (optional)

    IfSplit Typeis set to Range, this attribute will be set to the output value specified in the range list corresponding to each output point cloud.

    IfSplit Typeis set to Unique, this attribute will be set to the value of the component for each output point cloud.

    IfSplit Byis set to Last Return Only, this attribute will contain -1, since the last return value can vary from point to point.

    ClosedRanges To Keep

    When splitting by ranges, this parameter specifies the ranges to keep.

    • From: The start value for the range that you are classifying. This field accepts numerical input only and must be less than the value in the To field. Colors should be specified as comma-delimited values (for example, 255,100,50). If aFromvalue is not specified, it will be treated as an open-ended range.
    • To: The end value for the range that you are classifying. This field accepts numerical input only and must be less than the value in the To field. Colors should be specified as comma-delimited values (for example, 255,100,50). If aTovalue is not specified, it will be treated as an open-ended range.
    • Output Value: The value assigned to the output attribute for each range.
    ClosedUnique Values to Keep

    When splitting by unique values to keep, this which values should actually be kept. Values not included in this list will be discarded. Limiting a splitting operation to only desired values 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, clickbeside the applicable parameter. For more information, seeTransformer Parameter Menu Options.
