3D Point Cloud and Mesh Modeling

3D point cloud and mesh modeling are two essential techniques used in computer graphics and computer vision for generating 3D models of the earth’s surface or of physical objects.

A 3D point cloud is a collection of points in 3D space that represents the surface of an object. Point clouds can be generated by scanning physical objects using various sensors like LiDAR, structured light, or photogrammetry. Once a point cloud is generated, it can be used for various applications like virtual reality, gaming, and autonomous navigation.

On the other hand, mesh modeling involves converting the 3D point cloud into a mesh structure, which is a network of interconnected polygons that define the surface of an object. Meshes are widely used in computer graphics because they are easy to render, manipulate, and store. Once a mesh is generated, it can be used for various applications in fields like virtual reality, autonomous navigation, and 3D printing.
