3d painting?

[Darkmax]

some know how to draw in realtime in the virtual applications?, im trying to do a virtual classroom where some can draw on the blackboard with the wiimote or the mouse at the momment.

Im trying to this with on-the-fly, but with no results.


and maybe this is too dificult but also there is a way to recognize the draw? for example if the user draws a duck the application will load a duck model

but maybe this is asking too much just with the paiting thing im happy
