For each three-dimensional model, geometrical features related to object grasping are extracted based on the user data corresponding to the three-dimensional model. A machine learning model is trained to correlate the geometrical features with the labelling data associated with each corresponding grasping point pair and candidate grasping point pairs are determined for a new three-dimensional model. The machine learning model may then be used to select a subset of the plurality of candidate grasping point pairs as natural grasping points of the three-dimensional model.
