Hi PaQ,

I came across this software company http://www.seac02.it/ that specialise in visual solutions, they have a realtime renderer, LinceoVR which has a free student/non commercial license, I don't know if there is a catch though, also check out the video for their Eligo software, it's pretty cool.

LinceoVR renderer imports the main translated nurbs formats including 3dm as well as the poly formats, as for wireframe I'm not sure, I just came across this software not to long ago, so I haven't had a chance to try it out.

Cheers
