Abstract: In this paper, numerical ranges associated to operators on an inde nite inner product space are investigated. Boundary generating curves, corners, shapes and computer generations of these sets are studied. In particular, the Murnaghan- Kippenhahn theorem for the classical numerical range is generalized.
