Abstract
This chapter presents a collection of selected topics and applications related to point-based computer graphics. It aims at demonstrating versatility and wide range of possible applications. It discusses point-sampled 3D video representations, where 3D points generalize 2D video for the dynamic representation, compression, and display of 3-dimensional video. It includes the modeling and analysis of uncertainty in point clouds using statistical methods. The chapter focuses on the utility of irregular point samples for the visualization of irregular point data using so-called point glyphs. Finally, it addresses the computation of global illumination effects in point-sampled scenes and shows how such methods are employed in a production environment.
