PatchDance is a 3D graphics package. It is currently limited to
modeling, is PowerMac only, and outperforms essentially everything
else available on the Mac platform. It is patterned after heavy duty
professional software rather than familiar low end programs, making it
less "pretty" but very powerful. It is completely vertex-oriented and
spline based, and is more suited to organic type modeling than to CAD
or architecture. It is already being used for real work and has lots
of friends in the industry.
