World Space User Interface for Surface Pasting

Abstract

Surface pasting is a composition method that applies B-spline surfaces, called features, to any number of other B-spline surfaces, called base surfaces, in order to add details on the base surfaces. The locations as well as the size of the features are determined by transformations of feature domains. By modifying the domain layout of pasted surfaces, we can manipulate the appearances of features interactively in a Domain Space User Interface. However, this domain user interface is inadequate because the user cannot interact with the three-dimensional model directly. In this thesis, I propose a World Space User Interface that attempts to map three-dimensional user actions to two-dimensional domain operations and aims at providing a more intuitive and efficient modeling interface for surface pasting.
