Format of lines: if the coordinates of the points are defined in a specific format, the user can enter here a C/C++ string format to parse the coordinates, for instance:
%g %g %g will read X Y Z coordinates separated by spaces
%g, %g, %g will read X Y Z coordinates separated by commas
%*d %g %g %g will read X Y Z coordinates after discarding the first 'index'
Create Delaunay mesh after import: if enabled, after importing the points a triangle / tetrahedral mesh will be created using the Delaunay mesher.
