Computer aided drawing in three dimensions
First Claim
1. A computer system for aiding a designer in the design of an object and for generating an image of said object on a display, comprisingmeans for defining a three-dimensional designer'"'"'s work area,a first sensor representing the object and configured to be held by the designer in one of the hands and moved in three dimensions in said designer'"'"'s work area by the designer, said first sensor and said means for defining acting in combination to provide first signals that indicate the position of said first sensor in the designer'"'"'s work area,a second sensor configured to be held by the designer in the other one of the hands and moved by the designer in three dimensions in the designer'"'"'s work area, said second sensor and said means for defining acting in combination to provide second signals that indicate the positions of said second sensor in the designer'"'"'s work area, andmeans, responsive to said first signals and said second signals, for:
- (1) generating an image on said display that corresponds to a three-dimensional model of the object in a virtual work area that corresponds to the designer'"'"'s work area, said model having a shape defined by movement by the designer of said second sensor in said designer'"'"'s work area, and (2) controlling a position of said displayed image of the model in said virtual work area in accordance with the motion of said first sensor in said designer'"'"'s work area.

Abstract
A computer system for aiding in the design of an object, comprising a first sensor representing the object and adapted to be moved in three dimensions in a work area by a designer, the first sensor providing signals to the computer system that indicate its position and orientation in the work area, and a second sensor adapted to be moved by the designer in three dimensions in the work area, the second sensor providing signals to the computer system that indicate its position and orientation in the work area; the computer system responds to the signals from the first and second sensors by creating a displayed image corresponding to a three-dimensional model of the object in a virtual work area that corresponds to the designer'"'"'s work area, the model comprising lines that each have a shape and position that corresponds to movement by the designer of at least one of the sensors, and by controlling the position and orientation of the model in the virtual work area in accordance with the motion of at least one of the sensors.

33. A computer-aided method for aiding in the design of an object and generating an image of said object on a display, comprising
defining a three-dimensional designer'"'"'s work area with a device, representing the object with a first sensor configured to be held in one of the hands, providing a second sensor configured to be held in the other one of the hands, moving said first sensor in three dimensions in the designer'"'"'s work area with said one hand to cause said first sensor and said device to act in combination to provide first signals that indicate the position of said first sensor in the designer'"'"'s work area, moving said second sensor in three dimensions in the designer'"'"'s work area with said other hand to cause said second sensor and said device to act in combination to provide second signals that indicate the position and orientation of said second sensor in the designer'"'"'s work area, causing said computer system to respond to said first signals and said second signals by: -
generating an image on the display that corresponds to a three-dimensional model of the object in a virtual work area that corresponds to the designer'"'"'s work area, said model having a shape defined by movement of said second sensor in said designer'"'"'s work area; and controlling a position of said displayed image of the model in said virtual work area in accordance with the motion of said first sensor in said designer'"'"'s work area. - View Dependent Claims (34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
