Making 3D models: A challenge in man-machine communication

The purpose of this publication is to present a graphic 3D modeler with interactive interaction capabilities operating in real time. It may be used on both in Unix workstations and PCs. The modeler can be used to make and edit 3D reconstruction of articulated objects, a facility that is particularly useful in processing medical images generated by a CT scanner or magnetic resonance units. The modeler takes account of the physical characteristics of the objects manipulated and, in developing it, we have assumed that the prospective user will have the necessary expertise to be able to interact with and interpret the model.
