Interactive modeling using surface splines
Abstract
Currently available tools for smooth free-form 3D modelling follow a rigid design framework, especially in the initial stages of the design process. This thesis extends an existing free-form modeling paradigm, Surface Splines, to support exploratory design based on a small set of intuitive gestures and a hierarchical representation. Specifically, this thesis shows how to update Surface Splines efficiently and locally. It extends the representation to higher degree surfaces with additional flexibility in the input mesh and introduces a method to handle complexity with a hierarchical scheme. The new insights are integrated into an interactive sculpting environment that features direct manipulation techniques using virtual tools. Virtual tools provide a layer of abstraction between the user's view of the surface and the complexity of the underlying representation, and thus allow the user to concentrate on the modeling process.
