Abstract
In an interactive editing apparatus, a three-dimensional object to be edited is a set of polygonal surfaces which are arranged in a three-dimensional space and have the same number of sides. These polygonal surfaces are arranged on the three-dimensional space to display on a perspective view, the sides of the polygonal surfaces are linearly enveloped to express a polygonal three-dimensional object. When a user edits any one of vertex positions, data regarding the edited vertex and associated other vertex positions are updated. Further in the interactive editing apparatus, data regarding vertexes and faces of the object are managed using data cells, and shape data before the last editing are stored in the data cells together with present shape data, whereby an undo function is realized.
