Rendering a case with isosurfaces is one of the simplest things you can do with the METK. The isosurfaces are automatically generated when a new case is loaded. This will take some time, but the surfaces are stored as Open Inventor files and will be reused on a second load.
Needed modules: METKIsoSurface and METKViewer3D
Example network: METKRenderModes.mlab
