Constructing a 3D implicit object modeler by object oriented approach

A real-time 3D object modeler using a small subset of implicit functions for object modeling is described in this paper. It is suitable for 3D soft object modeling. The models can be created interactively while they are being rendered. This overcomes the traditional difficulty of applying implicit functions in real-time object modeling. The modeler is implemented using object-oriented programming techniques on SGI workstations using Open Inventor. Object-oriented design patterns have been used to form the overall modeler environment. The layout of the modeler can be formed by editing it using a script language without compilation. The object models created are compatible with the VRML format.
