Three-dimensional modeling method, system for three-dimensional modeling and non-transitory computer-readable storage medium

A three-dimensional (3D) modeling method includes obtaining geometric data representing a 3D structure and input parameters including factors determining an attribute of the 3D structure, generating grid data from the geometric data, sequentially generating at least one piece of down-sampled data from the grid data, pre-processing the input parameters to generate a 3D feature map, and generating attribute profile data, representing a profile of the attribute in the 3D structure, from the at least one piece of down-sampled grid data and the 3D feature map based on at least one machine learning model respectively corresponding to at least one stage.
