SAGA.pointcloud_tools.10: Point Cloud Attribute Calculator

{"id": "SAGA.pointcloud_tools.10", "title": "Point Cloud Attribute Calculator", "description": "The Point Cloud Attribute Calculator calculates a new attribute based on existing attributes and a mathematical formula. Attribute fields are addressed by the character 'f' (for 'field') followed by the field number (i.e.: f1, f2, ..., fn) or by the field name in square brackets (e.g.: [Field Name]).<br/>Examples:<br/>sin(f1) * f2 + f3<br/>[intensity] / 1000<br/><br/>The following operators are available for the formula definition:<br/><table
