What are the steps to generate a point cloud 3D model for beginners?

For beginners, generating a point cloud 3D model usually follows four core steps: capture raw data, preprocess (clean noise/outliers), register (align multiple scans), and export/visualize. Capture uses tools like 3D scanners or smartphone apps (e.g., Polycam); preprocessing removes errors from raw data; registration merges multiple scans into one coordinate system; export to formats like PLY/OBJ and view with software like MeshLab. If starting out, try free tools like MeshLab—its user-friendly interface helps beginners practice preprocessing and visualization without cost.
