Abstract
Methods and systems of editing an electronic geometric model are disclosed. The method includes receiving a first indication which indicates that a portion of the polygonal data is to be modified, and moving a first vertex of the plurality of vertices from a first subdivision position defined by a subdivision algorithm to a second position. The movement of the first vertex from the first subdivision position to the second position results in a modification of the polygonal data. The method also includes generating a first vector identifying the movement of the first vertex from the first subdivision position to the second position, which first vector is defined by an initial point at the first subdivision position of the first vertex and a terminal point at the second position of the of the first vertex, and associating the first vector with the subdivision position of the first vertex.
