Comparing 3D modeled objects

A non-transitory computer program comprising instructions for performing a computer-implemented method for comparing a first 3D modeled object and a second 3D modeled object that each represent a part or an assembly of parts, the first 3D modeled object including a first graphical representation and the second 3D modeled object including a second graphical representation, the method comprising:

• displaying the first 3D modeled object and the second 3D modeled object superposed in a same scene so that the first graphical representation is positioned at a location substantially confounded with a location of the second graphical representation in the scene;
• and
• upon manipulation of a user-interaction tool that controls at least one non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object, updating the displaying of the first 3D object and the second 3D object, the user-interaction tool being configured to be manipulated via a predetermined set of at least one action, a repetition of each respective action of the set controlling a respective non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object, the non-uniform variation being progressively performed with the repetition,
• wherein the user-interaction tool includes a slider, a graphical element representing the slider is displayed to the user, an activation action is performed prior to the respective moving action and the respective moving action is a move of the graphical representation of the slider in a respective direction, and/or the user-interaction tool includes a touch device and the respective moving action is a single touch moving action in a respective one of a predetermined pair of directions and/or a double touch moving action which is a respective one of a spreading gesture or a joining gesture, and
• wherein the respective moving action allows a user to browse through a continuum of rendering states which include at least three different rendering states, each of the at least three rendering states corresponding to a different relative visibility of the first 3D modeled object with respect to the second 3D modeled object displayed to the user.

A system comprising:

• a processor coupled to a memory and to a user-interaction tool, the memory having stored thereon a computer program comprising instructions for comparing a first 3D modeled object and a second 3D modeled object that each represent a part or an assembly of parts, the first 3D modeled object including a first graphical representation and the second 3D modeled object including a second graphical representation, the instructions causing the processor to be configured to
• display the first 3D modeled object and the second 3D modeled object superposed in a same scene so that the first graphical representation is positioned at a location substantially confounded with a location of the second graphical representation in the scene, and
• upon manipulation of a user-interaction tool that controls at least one non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object, update the displaying of the first 3D object and the second 3D object, the user-interaction tool being configured to be manipulated via a predetermined set of at least one action, a repetition of each respective action of the set controlling a respective non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object, the non-uniform variation being progressively performed with the repetition,
• wherein the user-interaction tool includes a slider, a graphical element representing the slider is displayed to the user, an activation action is performed prior to the respective moving action and the respective moving action is a move of the graphical representation of the slider in a respective direction, and/or the user-interaction tool includes a touch device and the respective moving action is a single touch moving action in a respective one of a predetermined pair of directions and/or a double touch moving action which is a respective one of a spreading gesture or a joining gesture, and
• wherein the respective moving action allows a user to browse through a continuum of rendering states which include at least three different rendering states, each of the at least three rendering states corresponding to a different relative visibility of the first 3D modeled object with respect to the second 3D modeled object displayed to the user.
