Item Point Sampling with Uniformly Distributed Lines(The Eurographics Association, 2005) Rovira, Jordi; Wonka, Peter; Castro, Francesc; Sbert, Mateu; Marc Alexa and Szymon Rusinkiewicz and Mark Pauly and Matthias ZwickerIn this paper we address the problem of extracting representative point samples from polygonal models. The goal of such a sampling algorithm is to find points that are evenly distributed. We propose star-discrepancy as a measure for sampling quality and propose new sampling methods based on global line distributions. We investigate several line generation algorithms including an efficient hardware-based sampling method. Our method contributes to the area of point-based graphics by extracting points that are more evenly distributed than by sampling with current algorithms.
