The method uses a weighting kernel to transfer particles to a regular grid, which forms the input to a convolutional neural network. We propose a regression-based regularization to reduce surface noise without penalizing high-curvature features. The reconstruction exhibits improved spatial surface smoothness and temporal coherence compared with existing state of the art surface reconstruction methods. The method is insensitive to particle sampling density and robustly handles thin features, isolated particles, and sharp edges.CCS Concepts: Computing methodologies->Physical simulation; Point-based modelsComputing methodologiesPhysical simulationPointbased models10.1111/cgf.1518113 pages
