pwgl-users: graphics into pwgl

Hello,

I'd like to represent some graphs into pwgl...
is there a way to represent opengl figures into a separate window (such
as one used for 2D-Editor) ?
(into tutorial about opengl-display-boxes in opengl, I haven't find a
way to do it, graphics seem to be represented
only onto the patch, inside the objet-boxe patch-representation, where a
double-click just open the lisp code.

Thank's for help,

Frederic Voisin
