摘要
A novel and efficient quasi-Monte Carlo method for computing the area of a point-sampled surface with associated surface normal for each
point is presented. Our method operates directly on the point cloud without any surface reconstruction procedure. Using the Cauchy–Crofton
formula, the area of the point-sampled surface is calculated by counting the number of intersection points between the point cloud and a set of
uniformly distributed lines generated with low-discrepancy sequences. Based on a clustering technique, we also propose an effective
algorithm for computing the intersection points of a line with the point-sampled surface. By testing on a number of point-based models,
experiments suggest that our method is more robust and more efficient than those conventional approaches based on surface reconstruction.
