Abstract

Point sets from range scanners are noisy and do not contain additional data such as normals, which makes it difficult to create a mesh for rendering. We use the moving least-squares (MLS) approximation to get normals and differential information, and approximate the surface near each point by an MLS surface. From this we obtain a splat of a new octagonal shape which approximates the local curvature at a point and allows fast and high-quality rendering. We show several results which demonstrate the practicality and benefits of our algorithm.
