Thanks for you quick reply.
This particular software actually references an internal chip on one of the IO boards, which makes it very secure, but we are at a loss to know which chip or prom it references. Even the manufacturer of the SGI machine couldn't answer.
We use the warp essentially as a way of controlling map placement onto 3D models.
The warp function in Photoshop is very rudimentary in comparison, giving only 9 subdivision spaces as compared to an infinitely subdivideable coordinate system on this older software. It also offers numerical input and saves the warps for implementation at any time in the future. It's also a great retouching tool for reshaping everything from waist lines to fantastical illustration texturing. You can check out some of our imagery and animation at
