使用open3d将obj格式转为pcd格式并保存（模型转点云）_open3d pcd

import open3d as o3d
 
mesh = o3d.io.read_triangle_mesh('./bunny.obj')
 
pcd = mesh.sample_points_uniformly(number_of_points=10000)
 
o3d.io.write_point_cloud('./example.pcd', pcd)

模型转点云，并保存，当然也可以使用poisson采样，更均匀，但是耗时更长

pcd = mesh.sample_points_poisson_disk(number_of_points=10000)
