Embodiment Construction

[0043] Hereinafter, a "three-dimensional" (or "3D") modeled object will be an object that allows three-dimensional (3D) graphical representation or its digital representation in a computer system. The 3D representation allows parts to be viewed from various angles (viewpoints). For example, when making a 3D representation, the 3D modeled object can be manipulated and rotated about any of its axes, or about any axis in the screen on which the representation is displayed. A three-dimensional scene is composed of a plurality of 3D modeling objects arranged in a three-dimensional space.

[0044] The idea underlying the invention is to use the cursor itself, whose shape is appropriately modified, as an interactor. This eliminates the time-consuming operation of associating an interactor with an object, then clicking on the interactor's element to select a transform. Also, there are no visual hindrances other than the small hindrance caused by the cursor that has to be there anywa...

Abstract

A computer-implemented method for manipulating at least one three-dimensionally modeled object (O1) in a three-dimensional scene displayed on a computer display, the method comprising the steps of: a)displaying, in the three-dimensional scene, a cursor (C) controlled by a pointing device (PD), the cursor having a shape representing three axes (X, Y, Z) of a coordinate system; b) selecting an object of the three-dimensional scene; c) detecting a drag operation performed by a user using said pointing device, said drag operation comprising a translation of the cursor, and selecting an axis of the coordinate system as a function of said translation of the cursor; and d) performing a manipulation of the selected object, said manipulation depending on the selected axis and by a length (L) of the translation of the cursor (PP) along the selected axis.

Description

technical field [0001] The present invention relates to a computer-implemented method for manipulating objects in a three-dimensional scene displayed on a computer display. It concerns the fields of computer graphics, authoring, computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM), and is applicable where manipulation (translation, rotation, resizing, etc.) All instances of digitally modeled objects. Background technique [0002] Three-dimensional modeling requires the ability to manipulate elements (objects) of a three-dimensional scene within the scene, eg, by selecting, zooming, translating, rotating, etc. [0003] In the early days of three-dimensional modeling, all these transformations were parametric, ie defined by numerical input by the user by means of eg a keyboard. This approach is slow, cumbersome, and decidedly unintuitive. [0004] Soon after, researchers began designing nonparametric user interfaces (UIs) for...
