创建一个平面和长方形体，采样转换为点云?

import time
import open3d as o3d;
import numpy as np;

mesh_box = o3d.geometry.TriangleMesh.create_box(width=0.4,
                                                height=0.6,
                                                depth=0.11)
mesh_box.compute_vertex_normals()
mesh_box.paint_uniform_color([0.9, 0.1, 0.1])

mesh_tx = mesh_box.translate((0.16, 0.15, 0))
#o3d.visualization.draw_geometries([mesh_box]) 

mesh_box_Floor = o3d.geometry.TriangleMesh.create_box(width=0.9,
                                                height=0.9,
                                                depth=0.005)
mesh_box_Floor.compute_vertex_normals()
mesh_box_Floor.paint_uniform_color([0.3, 233.3, 0.2])
 
pcd = pcdmesh.sample_points_uniformly(number_of_points=70000)
o3d.visualization.draw_geometries([pcd])
