Abstract

Although the support of surface features, where a surface feature represents a local geometric detail imposed on a surface, is welldefined on prismatic objects, this is not the case for sculptured surface models. Current methods often lead to data-explosion, high polynomial results, or procedural solutions. In this paper a method is described that allows explicit modelling of protrusions and depressions in free-form B-spline surfaces. As this functionality is intended to be used by industrial designers during conceptual design, distinct requirements are formulated to allow its use in this early stage of design. A method is described that calculates a blending geometry approximating G¹ cross-boundary smoothness effectively. Using these requirements and approximations, protrusions and depressions can be modelled with real-time response, and with unprecedented flexibility.

A surface blending approach for displacement features on freeform surfaces
2011, CAD Computer Aided Design
Embedding a number of displacement features into a base surface is common in industrial product design and modeling, where displaced surface regions are blended with the unmodified surface region. The cubic Hermite interpolant is usually adopted for surface blending, in which tangent plane smoothness across the boundary curve is achieved. However, the polynomial degree of the tangent field curve obtained symbolically is considerably higher, and the reduction of the degree of a freeform curve is a non-trivial task. In this work, an approximation surface blending approach is proposed to achieve tangential continuity across the boundary curve. The boundary curve is first offset in the tangent field with the user-specified tolerance, after which it is refined to be compatible with the offset curve for surface blending. Since the boundary curve is offset in a three-dimensional (3D) space, the local self-intersection in the offset curve is addressed in a 2D space by approximately mapping the offset vectors in the respective tangent planes to the parameter space of the base surface. The proposed algorithm is validated using examples, and the normal vector deviation along the boundary curve is investigated.
Local parameterization of freeform shapes using freeform feature recognition

Examples of advanced systems in the freeform domain are amongst others the Teddy system [37] and the Smoothsketch system [38], but the features that are created by these systems cannot be parametrically controlled. Cavendish and Marin [39] and Van Elsas and Vergeest [40] have proposed to create freeform displacement features by sketching on a freeform surface and lifting the sketched area out of the surrounding surface, but their methods are limited to displacement features. In his Ph.D. thesis, Pernot [41] proposed and extensively discussed a method to create freeform features using character and limiting lines (see Fig. 1).
Form feature modeling is a much used shape modeling technique that offers high-level control over a shape. When a feature-based interpretation of shape data is not available, e.g. when a shape is obtained by a laser range scanner or from a database of shapes, then the features must be reconstructed through feature recognition. Many methods for the recognition of machining features exist, but these methods cannot be used for freeform feature recognition, of which the complexity is much larger. In this paper, a new freeform feature recognition method is presented that is based on a new definition of the freeform feature concept. The method uses a three-step approach to feature recognition, in which first the global shape of a feature is matched to the target shape model. In a second step, this global shape is locally adapted to the target shape by adapting the definition of the feature. Finally, if the desired configuration of the feature has been determined, it can be used to reconstruct the target’s shape. In the first two steps, an evolutionary approach is taken to maximizing the similarity between the feature and the target shape. Finally, the target shape is reconstructed to incorporate the recognized feature. An extensive application example is given and the method is validated by applying it to a large number of artificially created test cases.
Incorporating free-form features in aesthetic and engineering product design: State-of-the-art report
2008, Computers in Industry
The use of free-form shapes has become mainstream to design complex products that have to fulfil engineering requirements as well as aesthetic criteria. Even if today’s CAD systems can easily represent free-form shapes by means of NURBS surfaces, their definition and modification still require a deep knowledge and a great skill in the manipulation of the underlying mathematical models. The implemented free-form shapes design operators are time consuming and do not enable fast modifications. To overcome these limits, some researches have been undertaken to try to adapt the feature concept, successfully adopted for the design of regular shapes, in the free-form domain. It gives rise to a set of free-form features modelling strategies. This paper gathers together the state-of-the-art of these advances. The various approaches are depicted and compared with respect to a very precise set of criteria expressing the needs in aesthetic and engineering designs. The limits and future trends are presented.
Freeform feature modelling: Concepts and prospects
2002, Computers in Industry
Much research has already been done on regular-shaped features, but more complicated, freeform features are now demanded by product designers. Freeform shapes are mostly represented by low-level representations, such as Bézier, B-Spline and NURBS patches. Freeform features provide a high-level interface to these low-level representations. The purpose of freeform features is faster and more intuitive modelling with more guarantees for a high-quality design. In contrast to the traditional ways of modelling with freeform surfaces, where low-level entities such as control points and weights are used to interact with a freeform surface, the user is offered a set of freeform features whose basic shape is fully defined by intuitive parameters. The design-by-features approach offers good opportunities for validity maintenance, by which only models that satisfy certain pre-defined validity conditions can be created. In this paper, the most important concepts in design by freeform features are surveyed, and issues such as classification and parameterisation of freeform features and freeform feature recognition are described. Wherever appropriate, promising research prospects are indicated.
Free-form design using axial curve-pairs
2002, CAD Computer Aided Design
Deformation of 3D shapes usually requires the use of a deformation tool. The freeform deformation technique requires the use of a lattice of control point for deforming an object. This may require a synchronized movement of the lattice control points in order to obtain the desired effects. The axial deformation technique allows an object to be deformed by manipulating an axial curve. However, unexpected twist of the object may be obtained. This is a result of the lack of control on the local coordinate frame of the curve. This paper presents a technique for deforming objects with a set of axial curve-pairs. The use of a curve-pair allows the local coordinate frame to be controlled intuitively. A curve-pair is composed of a primary and an orientation curve. The orientation curve is an approximate offset of the primary curve. A technique is proposed for maintaining the relation between the primary and the orientation curve when the curve-pair is adjusted. By associating a complex 3D object to a curve-pair, the object can be stretched, bended, and twisted intuitively through manipulating the curve-pair. This deformation technique is particularly suitable for manipulating complex shapes (e.g. decorative components) in industrial and aesthetic design, and is also suitable for modelling characters and animals with flexible bodies. Adjusting the curve-pair according to some motion constraints produces different postures of a character or animal model. This in turn can be used as decorative components for aesthetic design.
