This Point cloud data of trees extracted from 3D laser scanning were used to do analysis and research on the 3D modeling of trunks. The software of Geomagic Studio was used to separate and eliminate the noises of point cloud of trees, to acquire the point cloud data of trunks. On the basis of this, the data was resampled and modeled by different encapsulation methods. The result demonstrates that the model got by the method of maximal distance is the best.
