This thesis is an examination of the volume graphics pipeline with particular regard to the implementation of artistic (also known as non-photorealistic and expressive) effects. Over the last few years we have seen an evolution from volume visualisation to volume graphics but little work has appeared on adding artistic effects to the portfolio of techniques available in this new branch of computer graphics. The main achievements of this thesis are: • analysis of the volume graphics pipeline with special regard to the implementation of non-photorealistic effects; • the design of a new framework for the incorporation of new effects into the volume graphics pipeline; • the design and implementation of a wide array of artistic filters in modelling, rendering and image spaces; • a wide range of artistic images highlighting the contribution that computer graphics can make to the artistic community; • implementation of novel techniques for volume visualisation including 2+D pen-and-ink rendering. This work has showed the feasibility of introducing artistic effects through the medium of volume graphics. New techniques for producing pen-and-ink, oil painting, water colour painting, sculpting and abstract artistic images have been implemented. These techniques have been variously implemented in modelling, rendering and images space as was found to be appropriate in the new volume graphics framework. In particular the 2+D technique is a new method of enhancing image space algorithms by causing non-standard images with special properties to be passed out of the rendering stage of the pipeline. Parts of this research have been presented by the candidates at the 15th Eurographics UK Conference (Norwich), the 16th Eurographics UK Conference (Leeds) and at IEEE Visualisation 2000 (Salt Lake City).
