Manually its already possible to draw simple 3D draws like the above example (its basically just duplicate and move).
I have now read this manual
on how to make 3D boxes, but how do I apply transparency to e.g. a red box?
I mean; If I just have a red box, can Inkscape then figure out what the colour of the others sides should be, if I want transparency?
Group the 3 shapes composing the box and adjust the 'Master opacity' of the group (from the 'Fill and Stroke' dialog)
