A method is disclosed for indexing 3D digital models, retrieving them, comparing them and displaying the results in a 3D space. The method comprises four complementary parts, i.e. displaying, comparing/searching, reconciling the faces, and classifying the results. These parts can overlap with each other or can be implemented separately. A method is described for retrieving 3D models that share certain similarities of form with a reference 3D model, involving a first step of analysis in order to generate representations (descriptors). The process of searching/comparing 3D models based on descriptors partially related to the faces optionally requires a process of pairing and reconciling the faces. The results are displayed in a single 3-dimensional space and, owing to a mark on the faces of the 3D models, makes it possible to distinguish several types of difference between similar 3D models.

Method and system for displaying 3D models

Method and system for comparing 3D models

A method is disclosed allowing digital 3D models to be indexed, searched, and compared, and to display the results in a 3D space. The method comprises four complementary parts: displaying, comparing/searching, face reconciliation, and ranking results. Each of these parts can fit in one another or be used independently. The implementation of a process for searching/comparing 3D models based on descriptors at least partly related to faces requires a face reconciliation process (pairing of faces between 3D models).
