As 3D sensing technology keeps changing how a variety of industries operate, including robotics, self-driving vehicles, digital twins, augmented reality (AR), virtual reality (VR), and industrial inspection, more and more developers will use third-party libraries to help them analyze and interpret their captured 3D data.

Open3D and Point Cloud Library (PCL) are two of the most widely used open-source libraries for point cloud processing, as well as for analyzing the underlying 3D geometry, visualizing the point clouds, and reconstructing the geometry from the point clouds.
