RE: OpenGL and TPolyline3D

Hi, the required result (concerning the displayed lines) is something similar to what you obtain with the "qtgl ROOT" plugin. I have already used the QT-layer for other applications, but the code I'm working on in this moment is a part of a more complex code (in which the QT-layer is not used). Moreover I have already developed the complete event-display by using the "ogl" plugin (I also use the "built-in" style/cameras/light settings), then I think I can not switch to QT-layer so easily in this case.
Would it be possible to obtained the required result with open-GL? Thank you.
Cheers,
Diego
