Window reflections
Not Lite
Classify window reflections routine classifies points with pulse vector going through selected polygons. The polygons usually represent reflective wall surfaces, like windows or glossy metallic surfaces. Suitable polygons can be produced using tool vectorize wall polygons, for example.
This routine requires trajectories. The pulse vector is the line between point, and scanner positions.
The routine is useful for filtering error points caused by laser reflections.
