A Robust Mesh Growing Surface Reconstruction Algorithm based on

In order to overcome the disadvantages of mesh-growing method for large-scaleor normal information needed or pre-processing needed data, a robust mesh-growing surface reconstruction algorithm based on Octree will be proposed. Starting from an octree for dividing points cloud into space. Then select the flattest point and its nearest two points to be the seed triangle, and put the three sides into the queue. And make principles to ensure the growing of points be close to the optimal. Finally, we judge the type of points to determine topology reconstruction. Compared with TightCocone algorithm, this algorithm can deal with point cloud data without the normal information and pre-progressing and the reconstruction results are good
