creating 3D geometry from a huge list of vertices.

S.S.

Hi! I have a very complicated 3D geometry which is defined by 2048 points. I know this sounds crazy, but these points are important in order to describe the microscopic shape of the bounding walls of my flow medium - the flow is between two 3D surfaces, each having 1024 points. So, I have two vertex data files each having 1024 entries (x, y and z coordinates in each entry). I'm looking for some smart and efficient way to construct this whole geometry. This has to be done using GAMBIT only, as currently I do not have access to any CAD package. Any suggestions? Your comments and/or any help will be highly appreciated. Thanks in advance.
