[comp.graphics] 3D Surface Comparison Software for a PC ?

ross@isis.UUCP (Ross McConnell) (07/25/88)

Does anyone know of a PC software package that will allow me to
compare 2 3D surfaces. Lets assume that I have 2 files of XYZ
coordinates that describe 2 similar surfaces. I would like to
generate perspective projections of both, view them on a
graphics screen (EGA or Herc), and then overlay them, either
interactively or by providing a list of common control points.
I would like the "difference" surface to then be viewable
as well. I know I'm asking for a lot, bit has anyone heard of
a package that comes close? Thanks.
