Abstract

The present disclosure is to a computer-implemented method for flattening a digital 3D mesh representing a dental object. The method comprises obtaining the digital 3D mesh. The method comprises determining a circumferential mesh boundary in the digital 3D mesh, wherein the mesh boundary comprises multiple boundary vertices surrounding multiple inner vertices. The method comprises determining a target shape with a circumferential target boundary, wherein the target shape is planar. The method comprises for each vertex of the boundary vertices, performing coherent mapping to an anchor point on the target boundary corresponding to the respective vertex. The method comprises for each vertex of the boundary vertices, translating the respective boundary vertex to its corresponding anchor point on the target boundary. The method comprises flattening the inner vertices to the target shape to generate a flattened mesh based on the anchor points.
