Abstract
In modelling systems, the ability to assemble existing objects into more complex models and scenes is an important tool. However, it can be difficult and time consuming to accomplish this using traditional modelling techniques. This thesis presents techniques designed to facilitate the assembly of existing models into new forms. The use of subdivision surfaces as the basic geometric representation allows for a wealth of existing mesh models to easily be used with the algorithms. Sketch-based methods are used throughout with the goal of enabling quicker and more intuitive interaction, including a novel method for performing general transformations on objects with a single stroke. Models can be combined using Boolean operations, which make use of a subdivision surface intersection method designed to take advantage of properties of subdivision to improve efficiency.
