class mp2p_icp_filters::FilterByExpression

Overview

A programmable filter that evaluates a mathematical or logical expression for each point to decide into which output layer it should be moved.

Parameters :

expression: A string formula (e.g., “ring > 10”, “x^2 + y^2 < 4.0”)
output_layer_passed: (Optional) Layer for points where expression > 0
output_layer_not_passed: (Optional) Layer for points where expression <= 0

Variables available in expressions:

x, y, z: Spatial coordinates
intensity, ring,… or any other custom field in the input clouds.
