    A mathematical model for the expected-time analysis of line-clipping algorithms is proposed. Assuming that all clipping windows are equally likely, we demonstrate that the probability of a line segment being totally outside the window approaches the value of 8/9, provided that the line segments tend to be short and evenly distributed within a rectangle. Acceptance-rejection matrices are introduced... View full abstract»

    This paper builds on the principles of depicting transparency in hand-made line drawings, and develops a method to generate similar, but computer-generated, line drawings in a two-step process. In the first step, a brightness image is generated, which is used as a basis for the line drawing created in the second step. Three different methods derived from traditional drawing techniques are shown View full abstract»

    Publication Year: 1998, Page(s):300 - 306
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (92 KB)

    A method is presented which is capable of capturing surfaces of arbitrary topology. Derived from standard bicubic B´ezier patches, it “fills in” n-sided regions with four-sided patches. It is based on a recursive patch-midpoint subdivision algorithm on a rectangular framework of control points, which is then generalised to arbitrary control-point nets. At each step, a new set of ...

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (384 KB)

    Geometric models of high complexity are rapidly becoming commonplace. These models are usually represented by means of complex triangle meshes that create three important problems: visualization, transmission and storage. Interest in multiresolution representation is very keen, because it is an efficient method for addressing these problems. We propose a new data structure: multiresolution ordered...

  • A visual approach to the analysis of curve profile: a case in construction industry

    Publication Year: 1998, Page(s):321 - 326
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (92 KB)

    There are many qualitative and quantitative techniques which have been used for a variety of cases of curve fitting, smoothing and forecasting. All but a few have considered curves from a shape-geometry point of view. The paper argues that curve geometry contains characteristics that are descriptive of the nature of the subject area and therefore provides a viable alternative for the generation of...

    In our minds, we can create an imaginary environment of shapes and objects. A natural and intuitive way to externalize these imaginary shapes is through our hands by simply sketching or tracing their outline in space. If we could capture and then interpret our hand shapes, then we would be able to express spatial information in computer-generated graphical environments in a simple and extremely po...

  • Generation of quadrilateral meshes from triangular data with resulting smooth surface reconstruction

    Publication Year: 1998, Page(s):294 - 299
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (192 KB)

    A new method for surface reconstruction from an initial triangular mesh is introduced. The method transforms the mesh to a quadrilateral one and then builds a smooth surface on top of it. This approach is efficient for large collections of triangular patches, including difficult situations such as sharp junctions and n-patch vertices. During the reconstruction process, the number of mesh elements ... View full abstract»

  • Multimedia as a competitive success factor in textile and apparel industry

    Publication Year: 1998, Page(s):86 - 92
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (32 KB)

    This work is based on the assumption that severe difficulties may be found because of the generality of the agents in the textile process chain, during the implementation of “quick-response” strategies. These difficulties run through the inertia that characterizes the establishment of partnership relations between those different agents, as well as the communications between them. Ther...

    Nowadays, constraint solvers play a fundamental role in many graphical applications, including geometrical and mechanical CAD systems, layouts, user interfaces and animation. These applications use constraints to conveniently describe the relations between objects. Constraints are automatically maintained and satisfied by a constraint solver. So, numerical and tedious tasks are left to the solver ... View full abstract»

    Solid model abstraction is an integral part of parallel and process design. It is required for simulation and optimisation of the design and consists of retrieving a simplified model from the solid one, with appropriate dimension reduction and details removal. Unfortunately, current CAD systems do not provide the means for easy simplification of forms. Ongoing research efforts on abstraction yield... View full abstract»
