In less than a decade, volume graphics has established itself as an independent graphics technology. However, it is not yet as popular as contemporary surface graphics, which we attribute to a lack of well-founded modelling and rendering techniques, hardware and software. The work in this thesis addresses some of the problems associated with the field, such as the lack of a formal object model, primitive rendering techniques and the difficulty faced by the developers of both low-level rendering systems and high-level volume modelling interfaces. The main contributions of this work are summarised as follows: A flexible and low-cost object modelling framework, with rendering methods, for intermixing discrete and continuous volume data. Image-swept volumes: A new modelling paradigm in which attribute fields of volume objects are defined by sweeping discreet image or volume templates along arbitrary trajectories. A projection-based texture mapping method for volume objects. A method for rendering Bézier volumes and free-form deformations of volume objects. vlib: A volume graphics API, including detailed design and implementation details.
