Abstract
A computer-implemented method for designing a 3D model in an AR/VR environment including obtaining a 3D model in a 3D scene, the 3D model including at least one extruded section which results from the extrusion of a planar section, said extruded section being defined by a set of parameters, receiving a 3D user sketch in the 3D scene, at each iteration of a plurality of iterations: modifying at least one of said parameters, thereby obtaining a modified 3D model, performing a discretization of the modified 3D model, thereby obtaining a 3D point cloud, computing an energy which comprises a first term which penalizes an inconsistency between the modified 3D model and the initial 3D model, and a second term which penalizes a mismatch between the 3D point cloud and the 3D user sketch, said parameters being modified so as to minimize said energy, and outputting the modified 3D model.
