Proefschrift voorgelegd tot het behalen van de graad van Doctor in de Wetenschappen, richting Informatica aan de transnationale Universiteit Limburg te verdedigen door Acknowledgments Research is never done alone. On the one hand a researcher is inspired by the work and findings of others, and on the other hand he is influenced by his colleagues. I have(More)
Both ray tracing and point-based representations provide means to efficiently display very complex 3D models. Computational efficiency has been the main focus of previous work on ray tracing point-sampled surfaces. For very complex models efficient storage in the form of compression becomes necessary in order to avoid costly disk access. However, as ray(More)
Many real-world, scanned surfaces contain repetitive structures, like bumps, ridges, creases, and so on. We present a compression technique that exploits self-similarity within a point-sampled surface. Our method replaces similar surface patches with an instance of a representative patch. We use a concise shape descriptor to identify and cluster similar(More)
During the last couple of years, point sets have emerged as a new standard for the representation of largely detailed models. This is partly due to the fact that range scanning devices are becoming a fast and economical way to capture dense point clouds. Traditional rendering systems are impractical when a single polygonal primitive contributes less than a(More)
