I loved using Imagine on the Amiga and I still do use Lightwave albeit on a PC.
What I would love to see is a realtime 3d app that uses one of the new vide cards to H/W render.
Also I would love the renderer to be another app so that work could carry on when test rendering.
We had a 'chicken wire' metaphor and now we have the 'clay' metaphor, so what's next?
Substance!
I think the substance such as metal, cloth, plastice, etc can be defined first and the tools and their behaviour derive from there.
Just a thought.
