Re: 3D visualization in 3D
I started (and stopped) at the hardware requirements for 3D: they are extremely high end for a live model review, well beyond most budgets. I didn't get around to seeing how to produce 3D movies.
Re: 3D visualization in 3D
There's a couple people out there doing Stereoscopic 3D. I haven't had a chance to use it yet, but its on my "projects" list. nVidia makes really nice battery powered 3D glasses that work with certain graphics cards they make. You can use Cinema 4D, Maya or 3dsMax (probably some others). I think Inventor has that option too? Asus makes a nice 3D projector under $1000. Any budget you have will basically center around that (not inclu'd software)
