Grid modeling is new and the product is GridPro(tm)/sb3020. Grid modeling can be viewed like an extension of computer aided geometric design (CAGD). In distinction, pointwise distributions are important, the action is volumetric, and there is the concurrent integration of both control point arrays and specified boundaries. In addition, there is a rich supply of tools (eg. rubber banding, elliptic methods, etc.) to model by moving control points to new positions. Modeling can be performed with fixed boundary points, points moved along the boundary, a totally free-formable boundary, or some combination of these.
