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)
