Feature-based and unified surface geometry processing for product modeling

With the combination of reverse engineering, shape modeling and feature-based design, there could be a huge opportunity in industry to achieve highly efficient and rapid design of products, such as car and aircraft bodies as well as the derived modules and parts. Modern CAD technology has enabled sophisticated surface modeling tools and application which are well adopted in industrial product development. However, the surface models created in industry and those created from scanned points are fundamentally different. To support industrial design practice where clay models are used as a way to reflect industrial and artistic design elements, scanned surfaces have to be incorporated (typically by importing point clouds) into CAD design model as the initial input and further propagated into downstream models of products, modules and parts. This proposed research is aiming to apply surface feature modeling approach with explicit context constraints in a specific product field and enable feature-based modeling embedded with advanced geometry processing methods, which will realize rapid complex geometry’s creation, modification and manipulation in product modeling processes and also extend computer graphics techniques to be adopted to practical engineering cycles.
