Abstract:
1. A method of producing a three-dimensional structural sketch of an object having two-dimensional body parts, the method comprising: detecting, using a computer, a unary property of each part of a given two-dimensional sketch and relational properties between the two-dimensional body parts; receiving the detected unary properties and the two-dimensional body parts, converting the two-dimensional body parts into body part node ellipses having visual elliptical shapes together with the detected unary properties, and converting all of the body part node ellipses into three dimensional body part nodes having three-dimensional visual shapes by inflating the body part node ellipses according to the detected unary property respective to each two-dimensional body part; and receiving the detected relational properties and the nodes, connecting the three-dimensional body part node ellipses to each other according to the detected relational properties, and generating a three-dimensional structural sketch depicting the given two-dimensional sketch in three dimensions, wherein the unary property includes geometric property and the relational property includes topologic property, and wherein the three-dimensional structural sketch is built entirely of three-dimensional body part ellipses from the two-dimensional sketch.
