select_pt - selects points from a point cloud associated with scalar values smaller/bigger than a given threshold.
select_pt [-t double|--threshold double] [-i|--invert] [-?|-h|--help] FILE
select_pt selects the points of a point cloud with a scalar value smaller (or bigger) than a given threshold. The scalar values are read from FILE and the point cloud from the standard input (the number of points and scalar values must be equal). The resulting point cloud is returned to the standard output. Used in conjunction with pt2string(1) and GNU Octave or a similar program, complex filters can be defined.
Format of the scalar file:
only points associated with scalars smaller than value will be output (default: 1.)
selects points with a scalar value BIGGER than a given threshold.
