I would like to use the picking functionnality, ie pick a point of a surface, and get it in my plugin, for instance to compute a streamline.<br>StreamTracer offers this functionnality but it actually does not work because the pick point is not necessary a point of the dataset, as with the picking functionnality when "select points on" is selected. Thus, in case of a surface, the point does not lie on the surface ad no streamline is computed (I mean with StreamTracer).<br>So my question is: is it possible to pick a point of a surface with the "select points on" functionnality and get it back in my filter, connected to the SetOrigin(double [3]) function for instance?<br><br> <br /><hr />Avec Internet Explorer, surfez en toute discrétion sur internet <a href='http://clk.atdmt.com/FRM/go/182932252/direct/01/' target='_new'>Cliquez ici !</a></body>
