To parallelly optimize a polygonized iso-surface on GPU, we adapt the surface flow method [24]. This method moves mesh vertices on a surface without changing its topological connectivity. We modify the three flows in [24] to make it more efficient. These flows optimize vertex positions, normals, and triangle … See more The vertices of the initial mesh are not exactly on the iso-surface because the extraction process is approximative. We project the vertices … See more Taubin [33] smoothes a mesh by first smoothing its normal field and then repositioning the mesh vertices according to the new normals.
