In 3D modeling AI, a point cloud is a set of 3D data points (with X/Y/Z coordinates, often plus color/reflectivity) that represent an object’s or environment’s surface, captured by sensors like LiDAR or RGB-D cameras.
AI uses this raw data to reconstruct detailed 3D models—processing points into meshes, textures, or CAD files without manual drawing. It’s foundational for AI-driven modeling in industries like construction (site scanning) or automotive (part design).
