What's the difference for you between a renderer and a modeller? As for the 
preview, there could be a generalized 3D widget which is capable of loading 
different formats, and the modeller builds on it - otherwise a QGLWidget 
contains everything you need. For example, a preview could contain a context 
menu for zoom and rotation, while other viewers wouldn't need that 
functionality, instead they need to toggle between points, lines and polygons.

Yep, that's a nice idea.

I assume you want to use this for getting the 3D data out of different 
media/formats. This is IMO not so easy, there are different representations 
of the data itself, like tree structures or object-orientated ones. After 
all, this is a point where it comes to pure math.

Definitively. It's one of the most requested features we get. But it does way 
too much depend on the hardware, so you cannot easily integrate it within the 
desktop where it's not necessary.

True. There are some for non-KDE yet like Vertex3d and pp, so to attract 
artists at least this functionality should be provided. A 3D game doesn't 
create itself from 3D objects though.

3.0? That's not a long time for these plans.

Play around more :)
If such a modeller becomes usable, I'd be happy to contribute an example 3D 
game (thinking about a time frame of about half a year here).
You should create a scratch page somewhere on the web where ideas can be 
thrown in, to get a more detailed view on the planned projects. Think about 
3D noatun visualization plugins, games (or maybe their map and characters 
editors at first), CAD applications, 2-dimensional usage of OpenGL (an often 
forgotten functionality), ...
