... then calculate an error-minimizing point in each cell based on a quadratic error function (QEF). Based on a novel adaptive sampling condition, we construct adaptive octree cells such that a QEF point in each cell can capture the shape of all the geometric elements inside the cell. Finally we reconstruct...
