The assign filter allows you set the value of a dimension for all points to a provided value that pass a range filter.

Example 1

This pipeline resets the Classification of all points with classiciations 2 or 3 to 0 and all points with classification of 5 to 4.

      "assignment" : "Classification[2:3]=0",
      "assignment" : "Classification[5:5]=4"


A range followed by an assignment of a value (see example). Can be specified multiple times. The assignments are applied sequentially to the dimension value as set when the filter began processing.
