| 2014-10-15 06:50:23 -0600 | asked a question | [Viz] picking 3D points in a cloud Hello I work with Viz and I would like to pick interactively some points in a cloud to get their positions in 3D. (At this stage, I create a viewer and I create the points cloud with a widget cloud.) How should I do? I took a look in the documentation and I found nothing expect to pick 2D points with a mouseEvent but the result is only the coordinate of the points i have picked in the window (i,e the coordinate in pixel of the mouse in the window). I hope that someone could help me ! Regards. A. |
