Abstract

The invention relates to an applicator device (10) in the form of a brush or a felt-tip pen, including: a gripping means (16); an applicator element (12) connected to the gripping member (16), whereby said applicator element can deform parallel to a direction of application (A1) of the applicator device; and means for biasing the applicator element (12) along at least two different directions parallel to the direction of application (A1). In one embodiment of the invention, the device includes a supporting element (14) for supporting the applicator element (12) and the above-mentioned biasing means can co-operate with the supporting element (14) in order to move a first portion of the applicator element (12) in relation to a second portion of the applicator element (12) parallel to the direction of application (A1).

Abstract

The invention is directed method of computer-aided design of edges connecting faces of a modeled object, the method comprising a step of: - determining (S100 - S130) a structure of subsets of faces and edges of specified convex or concave type, by iteratively disconnecting (褖S120褖) faces connected by edges of one type from a parent subset, whereby said parent subset is decomposed into child subsets comprising either: - a non-connected face; or - faces connected by edges of the other type, in which case edges of said one type are maintained in said child subset, wherein said one type of edges is further alternated at each iteration of disconnecting; and the method further comprising a step of: - processing (S140) the structure from a given parent subset for rounding or filleting the one or more edges connecting child subsets thereof, according to the type of edge as specified in said given parent subset. More generally, the present invention may further be directed to the design of implementation of two distinct technologies for processing features connecting elements a model, in place of design of edges connecting faces of a modelled object.

Abstract

A computer-based method enables a selected part of a three-dimensional image on a screen to the followed throughout the three-dimensional image. In one embodiment, the method includes selecting a part included in the image, removing any obstacles included in the image that impede viewing of the part, moving a cursor along the part while constraining the movement of the cursor to the selected part, and, while moving the cursor, automatically removing, in a selected area of the viewing screen, any further obstacles appearing that impede viewing of the part during moving of the cursor so that the cursor can follow the geometry of the part. Thus, a user is provided with an unimpeded view of the part in the selected area when following the geometry of the part.
