Python Interface¶
For the C++ interface, see here.
Getting started¶
This tutorial shows how to import the open3d module and use it to load and inspect a point cloud.
[1]:
import open3d as o3d
Using external Open3D-ML in /home/runner/work/Open3D/Open3D/Open3D-ML
Open3D was not compiled with BUILD_GUI, but script is importing open3d.visualization.gui
Open3D was not compiled with BUILD_GUI, but script is importing open3d.visualization.rendering
Note:
Depending on the environment, the name of the Python library may not be open3d.so. Regardless of the file name, import open3d should work.
[2]:
sample_pcd_data = o3d.data.PCDPointCloud()
pcd = o3d.io.read_point_cloud(sample_pcd_data.path)
print(pcd)
PointCloud with 113662 points.
This imports the read_point_cloud function from the open3d module. It reads a point cloud file and returns an instance of the PointCloud class. print(pcd) prints some brief information about the point cloud.
Using built-in help function¶
Browse Open3D¶
help(open3d) prints a description of the open3d module.

Args:
filename (str): Path to file.
format (str, optional, default='auto'): The format of the input file. When not specified or set as ``auto``, the format is inferred from file extension name.
remove_nan_points (bool, optional, default=False): If true, all points that include a NaN are removed from the PointCloud.
remove_infinite_points (bool, optional, default=False): If true, all points that include an infinite value are removed from the PointCloud.
print_progress (bool, optional, default=False): If set to true a progress bar is visualized in the console
Returns:
open3d.geometry.PointCloud
