| 20100274818 | Method and System for Updating Object Data With Respect to Object Specifications in a Product Life Cycle Management System - The invention is directed to a Product Lifecycle Management (PLM) update process for updating objects with respect to specifications. The process invokes dependence relations between objects. It relies on building a directed graph, wherein objects are the nodes of the graph. An arc (also called “edge”) is directed from a second object to a first object, the latter depending on the second object according to dependence relations of the PLM system. Thus, the update can be carried by browsing the graph along the direction of the arcs in the graph. Owing to the reversion of the graph with respect to the dependence of objects, the simple solution of the invention guarantees that the update of an object occurs only when the ancestor object it depends on is up to date, and so on. This drastically reduces failures at update in practice. | 10-28-2010 |
| 20100262930 | Method, Program and Product Edition System for Visualizing Objects Displayed on a Computer Screen - This invention is directed to a method, a program and a production edition system of visualization of objects in a scene. The method according to the invention aims at indicating a distance between objects by modifying a property (like a rendering property) of a target object according to a distance to an active object. Typically, a light source is simulated and attached at the active object and the scene is accordingly modified dynamically. Such a method bypasses the basic materialization of the distance between objects. Hence, no display of extrinsic elements is mandatory and possible interferences are prevented. In addition, the method allows, by definition, a progressive modification of e.g. a rendering of the target object. Thus, modifications in the scene are better understood by the user and ergonomics are improved. | 10-14-2010 |

The method includes displaying, on a GUI, a 3D model as well as a cursor and at least one 3D animated icon which displays a representation of a respective transformation. The method further includes changing the state of an animated icon from static (i.e., a still frame) to animated when the user positions the cursor in the neighborhood of the icon, thereby illustrating the effect of the transformation. The method further comprises changing the icon to a different static state whenever the user selects the icon, at which point the icon will be displayed as a still frame that indicates that the icon has been selected. | 02-11-2010 |
