Hey Silvio
You'll want to use event.getWindowPosition. That
will give you the mouse location in your viewport.
Then you have to figure out your location of the mouse
in view coords (ie flip your y coords. These
functions conflict. One has the y at 0 in top left,
the other in bottom left or something like that).
Then you can use the M3dView function viewToWorld.
This will give you a vector and a point shooting out
from your viewport in the direction of the mouse.
