Claymore: Three-Dimensional Modeling Tool

We describes a method for manipulating a threedimensional object without considering conventional three independent orthogonal views. We apply the direct manipulation method to operate the threedimensional object. We propose \augmented manipulation" method which is an enhanced direct manipulation technique by using additional information. We implement three-dimensional modeling tool \Claymore" by using the \augmented manipulation" technique. Users can construct three-dimensional models in an intuitive manner.
