To turn a point cloud into a 3D model, you clean, align, and reconstruct the data with software to create a usable mesh.
Clean the cloud to remove noise (e.g., stray or duplicate points). If your data comes from multiple angles, align the scans for consistency. Then use algorithms like Poisson reconstruction to generate a polygonal mesh—the core of your 3D model.
For beginners, free tools like MeshLab or CloudCompare simplify these steps, letting you convert point clouds to editable models without complex setup.
