Item Interactive 3D Painting on Point-Sampled Objects(The Eurographics Association, 2004) Adams, Bart; Wicke, Martin; Dutré, Philip; Gross, Markus; Pauly, Mark; Teschner, Matthias; Markus Gross and Hanspeter Pfister and Marc Alexa and Szymon RusinkiewiczWe present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object as well as the brush surface. The generalization of 2D pixel-based paint models to point samples allows us to elegantly simulate paint transfer for 3D objects. In contrast to mesh-based painting systems, an efficient dynamic resampling scheme permits arbitrary levels of painted detail. Our system provides intuitive user interaction with a six degree-of-freedom (DOF) input device. As opposed to other 3D painting systems, real brushes are simulated including their dynamics and collision handling.
