Hello the community, I am new here and started a project, whose purpose is first to deal with a cloud of points. 100 000 points at least is quite usual for measuring systems. Also the points should be selectable (even if it is only in a defined or selected area).
Using following code, the performances in the viewer like usual ROTATE/ZOOM/PAN are far from being acceptable, even with 20 000 points. I am wondering if it is due to the BREP representation I used here ? So my question is : Do I need this Brep fonction to have selectable points ? Is there any way to have acceptable ROTATE ZOOM PAN for large points model ? ( Note I read I can pass a the list of points "liste" in the display.DisplayShape(...) but I didn t found out how ... but this will fast up the first display I guess, not ROTATE ZOOM PAN) Thanks for any help Francois -------------------------- CODE: ... pt = gp_Pnt ( coord_x, coord_y, coord_z ) liste.append ( pt ) for ppi in liste : display.DisplayShape( BRepBuilderAPI_MakeVertex (ppi).Shape(), update=False ) display.FitAll ( ) ... ---------------------------
