Abstract. We describe a new method for surface reconstruction based on unorganized point clouds without normals. We also present a new algorithm for refining the inital triangulation. The output of the method is a refined triangular mesh with points on the moving least squares surface of the original point cloud.

Keywords: multi-resolution; surface reconstruction; k-nearest neighbors; moving least squares.
