  • Designing of curves and surfaces using cubic splines with geometric characterization

    Publication Year: 1997, Page(s):82 - 94
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (800 KB)

    A constructive approach has been adopted to build interpolatory and B-spline like cubic spline curves with a more general continuity than β-continuity. This method provides not only a large variety of very interesting shape controls like biased, point and interval tensions but, as a special case, also recovers a number of spline methods like ν-spline of G.M. Nielson (1974), β-splines,... View full abstract»

    An empirical study of the methods available for visualisation of proposed building structures was undertaken at the University of Salford. This formed the basis for a structured survey of 103 construction related professionals. Their views were obtained on the mediums currently being used in the construction industry, the effectiveness of these mediums to communicate information; and the applicabi... View full abstract»

    The warping of scattered data points is a problem that is appearing in science and engineering. The basic problem involves the construction of a reasonable interpolation function that goes through some of the data points. In this paper, we propose a new spatial image warping algorithm which uses an elastic body spline to generate a warp function that interpolates scattered data points. The spline ...

    The paper reports a solution to the problem of image interpolation for generating, with high precision, an arbitrary cross-section from a series of slices. Shape-based interpolation as proposed allows the interpolation process to be influenced by the shape of the object. It is accomplished first by creating reconstructed shapes of the objects from a series of slices. Correspondence vectors distrib... View full abstract»

  • Normalised grid/motif based patterns-Islamic geometric patterns

    Publication Year: 1997, Page(s):252 - 257
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (396 KB)

    The studies of Islamic geometric patterns (IGP) show that the methods of generation are based on a set of classical gridding systems. They are hierarchical and primarily based on the sacred geometrical primitives (triangle, square and circle). With such patterns, symmetries are as visible as the forms themselves. They signify an obvious secondary meaning that is so often referred to, in the sacred... View full abstract»

  • Multiresolution data modelling for irregular data fields based on wavelets

    Publication Year: 1997, Page(s):64 - 70
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (848 KB)

    In many applications of scientific visualization, the data fields are so large that they are very expensive to store, transmit and render. Multiresolution offers a promising new approach for addressing these difficulties on a simple, unified way. Wavelets provide an extremely useful mathematical toolkit for hierarchically decomposing functions in ways that are both efficient and theoretically soun... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (408 KB)

    The transformation or blending of one 2D shape into another usually operates on sets of discrete points approximating the objects. This relies on a series of evenly distributed or properly positioned points on the boundary of the objects. Characteristics of the objects are not well considered. This paper presents a technique for transforming or blending shapes represented as a series of curve segm... View full abstract»

    Reviews the information visualization and interaction techniques needed to add another dimension to surfing the World Wide Web. Information visualization can be used to explore relationships by “drilling down” and retrieving more data within a region of interest in the visualized data, combining data mining, direct manipulation and data visualization with 3D Web tools.

    Scientific visualization is one of the important areas of computer graphics. This paper is concerned with non-negative C1-interpolation of non-negative data for visualization proposes. Using the rational cubic spline function of Sarfraz et al. (1997), necessary and sufficient conditions have been derived which ensure the generation of a non-negative curve through given non-negative data... View full abstract»

    A set of parameters to assess the objective quality of visualizations of a voxel-based data set, produced using a ray caster, is proposed as a first step toward the evaluation of the overall quality of these visualizations. Results obtained using synthetic data and a simple implementation of a ray caster are presented. The final goal of this evaluation is the computation of “confidence indic... View full abstract»

    The construction of information visualization systems is a difficult task. However, there is little research into the provision of software architectures for visualization systems to reduce this difficulty. Particularly, systems that provide a reusable support for the automatic management of the different levels of abstraction in which complex data can be observed cannot be found in current visual...

    Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs i... View full abstract»

    Space partitioning techniques are a useful means of organizing geometric models into data structures. Such data structures provide easy and efficient access to a wide range of computer graphics and visualization applications like real time rendering of large databases, collision detection, point classification, etc. Binary space partitioning (BSP) trees are one of the most successful space partiti...

  • Local convexity preserving rational cubic spline curves

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (376 KB)

    A scheme for generating plane curves which interpolates given data is described. A curve is obtained by patching together rational cubics and straight-line segments which, in general, is C1 continuous. It is a local scheme which controls the shape of the curve and preserves the shape of the data by being local convexity-preserving. A particular scheme is suggested which selects the tang...

  • Deformation of plane curves preserving Pythagorean hodographs

    Publication Year: 1997, Page(s):71 - 76
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (380 KB)

    Parametric plane curves are expressed as complex valued functions of a real parameter. The method is convenient for investigating Pythagorean-hodograph curves. A complex function transforms one curve to another curve in the complex plane. There are complex functions which preserve the Pythagorean hodographs of the curves. These functions can be used in deforming Pythagorean-hodograph curves. In pa... View full abstract»

    This paper presents a technique for smoothly blending some special categories of three-dimensional polygonal objects. Polygon blending is usually considered a two-part process: generating vertex correspondences and interpolating between corresponding vertices to create the intermediate polygons. This paper emphasises on the problem of automatic vertex correspondence determination. The proposed alg... View full abstract»

    This computer model was commissioned by the Tower Environs Partnership as part of the technical studies to underpin proposed enhancement of the surroundings of the Tower of London. It is intended to provide a sufficiently fine-grained photo-realistic facsimile to allow fine judgement of minor changes in landscape detail. Its credibility is underpinned by close correspondence to the original survey... View full abstract»
