  • 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»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1256 KB)

    The lack of tools for activity level visualisation of construction projects presents problems to planners when considering the future implications of their decisions. Current research into the application of computer graphics to construction planning goes not as far as the component level of a building. Though desirable, this approach does not match the efforts of planners who have to work at the ... 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»

  • Holographic imaging of lines: a texture based approach

    Publication Year: 1997, Page(s):272 - 278
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (740 KB)

    Holography is a method for three dimensional imaging of objects. We present an approach for the generation of holograms, exploiting standard graphics rendering methods and hardware. We focus on the visualization of objects composed of line segments, which allow for certain simplifications, and thus hologram generation speedup. Our method is based on the derivation of a holographic geometric equiva... View full abstract»

    The note lists some unsolved research problems concerning line (or edge) drawing algorithms for raster displays which seem to be still outstanding in 1997. Work in progress includes the so called “pixel perfect” speeded up versions of Bresenham's (1965) line drawing algorithm designed to exploit the parallel capabilities of modern display processors. Where should the build up of multi-... View full abstract»

    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»

    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»

    Conformal radiotherapy delivers high radiation doses to tumours whilst minimising damage to normal tissues. Therapy planning makes use of treatment simulation and computed tomographic images, which outline gross tumour volume and a dosimetric model. The larger planning target volume includes microscopic disease spread, target motion and set-up errors, effectively determining radiation beam collima... View full abstract»

    The use of 3D visualisation has long been established as a major breakthrough in closing the gap between a client's need and what is perceived by the designer to be the need of the client. Nevertheless, construction clients are increasingly demanding a greater participation in the process of design generation. This has been a welcome move by all parties, as less variation means less conflict. In s... View full abstract»

    This paper describes a system that uses visualisation to assist a user in dealing with the information returned from a search engine. The user's queries, and the documents they return, are represented by a 3D spatial structure that shows their relationships and provides a way of accessing and exploring the documents retrieved.

    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»

    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»
