Neighborhood Analysis, KD-Trees, and Octrees for Meshes and Point Clouds in Python

Distance calculations and neighborhood analysis are essential tools for understanding the shape, structure, and features of meshes and point clouds. This article will use three of the most widely used Python 3D data analysis libraries — Open3D, PyVista, and Vedo to extract distance-based information, visualize it, and show example use cases. As always all code, together with used mesh and point cloud data are provided. Who said that neighborhood analysis for 3D objects should be hard?Examples of calculating …
