Abstract
Taking one step futher in specialized footwear CAD applications, is generating the base shoe model, instead of interactive drawing. This original technique, treats a shoe design as a parametrical form, by associating modelling mathematical laws with each classical design step from the theory. By implementing this concept in computer programming, an operator can create a solid design in a few seconds, and a shoe family (base model variations) in a few minutes, which represents a huge time economy, comparing to other design methods. The main advantage is that the operator resources are saved, so he can focus on the final design sooner, rather than paing attention to the design steps. Also, because entire design is starting from scratch, this application has an educative roll, by helping students to undertstand the correlation between footwear design steps. This paper shows which mathematical laws are used to convert a design step in a software rendering routine, the final application friendly-interface, exemples of different rendered shoe models and the integration of this software in the CAD specialized footwear applications . The mathematical laws are treated from a general perspective, and the software is focused on a management for this laws, how they are combined and their usage restrictions; also, approximation code for rendering the shape is explained here; the application allows the operator to use three different level for data regression and interpolation, depending on the hardware performance. The interface is build intuitive, based on the design parameters for footwear base models. For faster rendering, there had been presented sets of variables that trigger the software behaviour, and so the final design. Finally, the integration of this software within the CAD enviroment treats compatibility issues with other applications, like the files encryption qnd modular integration. |
