Abstract

The present disclosure relates to a computer-implemented method for generating a digital 3D representation of a dental object, the method comprising the steps of: obtaining one or more 2D image(s) of the object; generating, based on the one or more 2D image(s), point cloud data, wherein the point cloud data comprises multiple points representing surface points of the object; and generating, based on the point cloud data, mesh data comprising multiple polygons representing the surface of the object. The step of generating mesh data comprises: obtaining geometric information based on the one or more 2D image(s), wherein the geometric information is indicative of a rate of change of one or more surface characteristic(s) in multiple surface sections of the object; determining a mesh resolution for each surface section based on the geometric information; and generating a mesh for each surface section with resolution determined for the respective surface section.
