i am currently working on a 2d-done-in-3d "project" of my own. i dont
fiddel with the "depths" as i fear having to much trouble with getting
the propotions, mass, ... right.

i use "polygons" (transformed in a tri-mesh-fan) for the level - so
having a polygon in a "real" 2d ode would be great to have (simply for
the level).

my player for now is a sphere and the things in the level are boxes - so
bascially up to there the stuff would be useful.

running this with 3d ode feels quite stable - at least for me. after
each step i eliminate everything that would make things move into/out of
the screen (Z) - this also seems to work good. at least i would exepct a
performance gain by using real 2d ode.
