The ability to picture the invisible is a key tool in the armoury of any scientist. In materials science we are faced with a particular challenge - how do deal with visualisation from the atomic scale, all the way up to the macroscopic. With an emphasis on data generated by computer models, this project will begin by surveying the state of the art in materials visualisation, and attempt to answer the following questions: Can we do better? How can we find the hidden gems in a mass of data - either in models containing millions of atoms, or in millions of models? How might emerging technologies (such as virtual reality) be used by materials scientists?
