Fast point-cloud wrapping through level-set evolution

By Marco Marcon, Luca Piccarreta, Augusto Sarti and Stefano Tubaro


In this paper we propose a fast algorithm for the reconstruction of surfaces from sets of unorganized sample points. The method is based on the temporal evolution of a volumetric function’s level-set derived from a PDE used in fluid dynamics. The reconstructed surface can be thought of as the front of a fluid that progressively fills up the space surrounding the cloud of points until it wraps them around. One interesting feature of this approach is its ability to model complex topologies using only properties such as fluid viscosity and vorticity. Another remarkable feature of this algorithm is its computational efficiency, which makes it suitable for interactive surface modelling [1] 1
