No, considering ATI currently does Truform in software via its drivers anyway.
There's a software Truform that's being developed for N64 graphics emulation, as well.
One of the software sources for ATI's Truform is available here:
http://www.ati.com/developer/sdk/Npatch/npatchresource.htmlThe "exporter and viewer".
Using DXTweaker it's possible for "Force N-Patches". Truform is ATI's little marketing name for N-Patches. I use it because it's just easier to type.
However, you can only force N-Patches on DXTweaker on hardware that supports it, which isn't nVidia cards since they want to be anticompetitive (the cards now can do it just fine). However, using DXTweaker one *should* be able to write a plugin for the Software Truform, making it run on any system.
Anyone with 3DsMax (which isn't me) should be able to export an FF7 model into the Truform viewer for a more accurate view of what a Truformed model might look like.
