Abstract
IGEL is a new shape modeling tool mimicking heat cutters for 3D computer graphics. Heat cutter os a tool fir processing styrene form. Since blades of cutters are steal wires, users can freely bend them. IGEL realizes this operation by a sketch input system. IGEL has two different modes, 2D and 3D modes, and users can switch them freely. In 2D mode, users can draw the shapes of cutters freely. In 3D mode, users can cut the styrene forms using their own cutters. Our implementation represents the styrene forms as triangular meshes, and cuts the meshes according to the user's operation. This paper describes the processing flow of IGEL, shows examples, and discusses our future works.
