ABSTRACT:
A computer implemented method of annotating a geometric figure displayed and manipulable in three-dimensional representation on a display of a computer system with a pointer is described. The pointer is also displayed and manipulable in three-dimensional representation on the display. The method associates multimedia functions with the geometric figure. The pointer is positioned to point at an area of the geometric figure using a control device. The geometric figure is displayed in a particular view orientation when the pointer points at the area of the geometric figure. The pointer is then oriented three-dimensionally such that the pointer can point at the area of the geometric figure at a desired angle. The particular view orientation of the geometric figure with the pointer can be preserved such that the particular view orientation of the geometric figure with the pointer can later be retrieved. The pointer can be activated by attaching a marker to the pointer using the control device. When the pointer is activated, the pointer can be associated with a multimedia function such that when the pointer is again activated, the multimedia function is executed.
