stereoscopic 3d math function plots?

[alaskatroll]

Anyone know of any 3d graphing utilities that i could use stereoscopically with my passive monitor? I think it would be neat, and somewhat helpful, ad i'm taking calculus 3 and we're getting into some weird 3d function graphs.

the closest i've come so far is using microsoft mathematics, exporting the graph as an image, slightly rotating it horizontally, exporting again, merging them into an SBS image, then opening them with tridef 3d media player.

I'm looking for a way to view them stereoscopically within the program, so i could see the shape evolve as i tweak or automate constants.
