(promotor) Degree granting institution Delft University of Technology Date 2018-05-04 Abstract The ubiquity of large virtual worlds and their growing complexity in computer graphics require efficient representations. This means that we need smart solutions for the underlying storage of these complex environments, but also for their visualization. How the virtual world is best stored and how it is subsequently shown to the user in an optimal way, depends on the goal of the application. In this respect, we identify the following three visual representations, which form orthogonal directions, but are not mutually exclusive. Realistic representations aim for physical correctness, while illustrative display techniques, on the other hand, facilitate user tasks, often relating to improved understanding. Finally, artistic approaches enable a high level of expressiveness for aesthetic applications. Each of these directions offers a wide array of possibilities. In this dissertation, our goal is to provide solutions for strategically selected challenges for all three visual directions, as well as for the underlying representation of the virtual world.
