Having some experience already with 3D transformations
and different projections from 3D to 2D, I'd like to ask some
questions or to give some suggestions about this, just to 
get a personal impression:

Maybe it would already help to have some formulas to see,
how such transformation can be implemented?

If you have it for some examples or even some simulations,
how this works this could help. For example PHP-scripts doing 
the  transformation and presenting the result in current SVG,
this could be already used to explore the behaviour
and possible difficulties and applications ...

Especially do this conversions conserve the structure
of the path (straight lines are still straight lines or points,
cubic beziers are converted just in other cubic beziers 
just by conversion of points and control points etc) or
does it create completely new paths, a viewer has to
calculate for each device pixel?
I think, with such a simple approach the viewer has
not to care in a specific way about the rendering order
as this happens for non trivial 3D-2D projections?
