I remember "geomview" well. It was widely used in the old days. But interactive 3d is another topic. In this case I would focus on VTK and ParaView (both BSD): https://en.wikipedia.org/wiki/VTK https://en.wikipedia.org/wiki/ParaView Writing related 3d format files is quite easy in fricas. > > Just an idea. > > Andrey > -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
