Abstract
Abstract A computer aided design method and system for displaying and manipulating an image of all or part of a human body is disclosed. To display an image in accordance with the invention an electronic memory stores data representing in an anthropometrically accurate manner each of a plurality of segments of a human body as a polyhedron having vertices whose coordinates are measured with respect to a joint center point. This data is then used by a graphical display device to display an anthropometrically correct image of one or more segments of a body, each displayed segment being displayed as a polyhedron. By applying rotational, translational or scaling transformations to the coordinates describing the vertices of the polyhedrons, it is possible to manipulate the corresponding graphical image of particular body segments.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
191 words
A computer aided design method for displaying and manipulating an image of all or part of a human body comprising the steps of accessing under the control of an electronic processing unit an electronic memory storing the coordinates of a multiplicity of vertices for each of one or more polyhedrons representing in an anthropometrically accurate manner a corresponding human body segment, the coordinates of said vertices being generated by electronic digitization of a real three-dimensional object in the form of all or part of a human body, electronically displaying on an electronic graphical display device an anthropometrically correct image of one or more segments of a human body utilizing the coordinates stored in said electronic memory, each of said segments being displayed as a polyhedron having a multiplicity of vertices connected by lines to form polygons, and electronically manipulating said image of said one or more segments of said human body on said graphical display device in response to user signals transmitted from an input-output device to said processing unit by utilizing said processing unit to transform the coordinates of the vertices of the polyhedron representing at least one body segment.
