Abstract
A method edits a 3D model using 2D images. First, a projected range image is generated from a 3D model. The projected range image is edited using a 2D editor. A projected distance and a cliff distance from a plurality of 3D points to a 3D surface of the 3D model are determined using the edited projected range image. The projected distance and the cliff distance of each of the 3D points are combined to determine a distance from each 3D point to the 3D surface so that the distances forming a distance field of the edited 3D model.

A method for editing a 3D model using 2D images comprising:
- generating a projected range image from a 3D model;
- editing the projected range image using a 2D editor;
- determining a projected distance from a plurality of 3D points to a 3D surface of the 3D model using the edited projected range image;
- determining a cliff distance from the plurality of 3D points to a nearest cliff of the 3D surface using the projected range image;
- and
- combining the projected distance and the cliff distance of each of the 3D points to determine a distance from each 3D point to the 3D surface, the plurality of distances forming a distance field of the edited 3D model.
