Method, program and product edition system for visualizing objects displayed on a computer screen

摘要

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.

主权项

1. A computer-implemented method of visualization of objects displayed on a computer screen, the objects being displayed in a scene, within a graphical user interface of a product edition system that performs Computer-Aided Design (CAD) operations on an object, comprising the steps of:
displaying at least two objects in a scene within a graphical user interface of the product edition system that performs CAD operations on an object; identifying a first object and a second object amongst the at least two objects displayed in the scene, the first object being identified as an active object that is an editing tool for working on at least one of a geometrical property and a physical property of the second object upon user actuation; attaching a light source at the first object and simulating effects of the light source, said attaching resulting in the first object effectively serving as a single tool that combines functions of the editing tool and the light source; with the light source attached at the first object, modifying at least one of the geometrical property and the physical property of the second object according to a distance between the first object and the second object; and modifying the scene according to the modified ones of the geometrical property and the physical property of the second object and according to the simulated light source effects, the first object having the light source attached and as a result combining functions of the editing tool and the light source; and storing in computer memory the modified ones of the geometrical property and the physical property of the second object.
