Open3d 点云可视化

import open3d as o3d
import numpy as np

mesh = o3d.geometry.TriangleMesh.create_coordinate_frame() # 坐标轴
T = np.eye(4)
# T[0, 0] = -1 # x 轴翻转
# T[1, 1] = -1 # y 轴翻转
# T[2, 2] = -1 # z 轴翻转
# T[0, 3] = 10 # x 轴平移
# T[1, 3] = 10 # y 轴平移
# T[1, 3] = 10 # z 轴平移
# T[3, 3] = 10 # 缩小倍数

# x,y 轴交换
T[:2, :2] = [[0,1], [1,0]]

mesh = mesh.transform(T)
