| Abstract;After we sketch the design of a product in cyberspaces, we can obtain each pars of the product applying a cell decomposition based on cellular model operations and the homotopy theory to the sketched result. When we perform cell decomposition, we can specify the manufacturing procedures of a product as homotopy invariants using the homotopy theory. Using the parts and the manufacturing procedures of a product, and cell attaching functions accumulated in the cyber design database according to these processes, we show first that we can perform the real design of soft products, the shapes of which are constantly changing. We then show that varied sizes can be uniformly specified by the cellular model. Thus, the cellular model is far powerful than geometric models. The design of a bag is taken as an example of soft object design. (author abst.) |
