    This paper discusses the distribution of inflection points and singularities on a piecewise parametric rational cubic spline. Necessary and sufficient conditions for a convex data have been presented. A high degree of smoothness is obtained with automatic estimation of two families of shape preserving parameters for local convexity View full abstract»

    A construction workspace is a dynamic environment that allows little time to obtain and update the graphical and image modeling information that is required in construction equipment operations. Comprehensive 3D models of the workspace require computationally intensive and expensive imaging processing, and usually take much longer than the ongoing construction operations permit. Rapid 3D positioni... View full abstract»

    The PC software AMCE provides building actors (owner, project authors…) with a multiple criteria decision aid (MCDA) procedure to optimise the building envelope cost and energy performance, during sketch design, when most important choices are fixed. Two main modules are linked: (i) the first manages parameters describing the project requirements; (ii) the graphic pen-based module allows on... View full abstract»

    In order to obtain a good spline model from large measurement data, we frequently have to deal with knots as variables, which becomes a continuous, non-linear and multivariate optimization problem with many local optima. Hence, it is very difficult to obtain a global optima. We present a method to convert the original problem into a discrete combinatorial optimization problem and solve it by a gen...

    Describes approaches to the visualisation of customer behaviour and proposes an innovative metaphor for information visualisation. The helix metaphor is adopted as a technique to render behavioural temporal data in a user interface design incorporating a 3D representation. The helix metaphor extends the conceptual model of a spiral representation along a linear perspective, and accommodates the vi... View full abstract»

    This paper describes work on mapping from an abstract intelligent physical modelling system to a virtual modelling environment for design visualization. It also addresses related questions: Why is there a current revival of interest in these techniques? What is different now? Why use abstract representations? What were these systems for in the first place? What might be their new role in the futur... View full abstract»

    Tensegrities are a special type of tensile structures that offer a viable alternative to conventional space covering structures. The morphology of tensegrity networks is uniquely and directly related to their structural and mechanical properties. Geometric and topological complexity is a characteristic of the morphology of tensegrity structures and accounts for significant difficulties in the stud... View full abstract»

    Many non-speaking people use augmentative and alternative communication (AAC) systems to assist them to communicate with other people. Access to an AAC system is generally slow for its user, who may have other disabilities as well as being non-speaking. An AAC system can contain stored words, messages and stories for use in communication, and there can be a large quantity of such information for t... View full abstract»

    This paper presents the design of a simulation environment for the modelling, visualisation and optimisation of construction site layouts. This construction site workspace application aims to support the site planning task by analysing space and risk on the site and generating automated site layouts which satisfy a combination of cost, efficiency and safety criteria.

  • Adaptive fairing of surface meshes by geometric diffusion

    In triangulated surface meshes, there are often very noticeable size variances (the vertices are distributed unevenly). The presented noise of such surface meshes is therefore composite of vast frequencies. We solve a diffusion partial differential equation numerically for noise removal of arbitrary triangular manifolds using an adaptive time discretization. The proposed approach is simple and is ...

    A set of algorithms has been developed and evaluated for 3D and 2½D rapid prototyping replication of 3D reconstructions of cancellous bone samples. The algorithms replicate a voxel map without any loss of fidelity, so as to increase the validity of the comparison of mechanical tests on the 3D reconstructed models with those predicted by finite element analyses. The evaluation is both in ter... View full abstract»

    Finding a previously visited page during Web navigation is a very common and important process. Although most commercial browsers incorporate a history mechanism, when accessing pages that were recently visited, users still rely mainly on the “Back” button. In this paper, we studied the effectiveness of visually enhanced history browser mechanisms on Web navigation. We used three diffe... View full abstract»

    The retrieval performance of content-based image retrieval (CBIR) systems still leaves much to be desired, especially when the system is serving as an interface to an image collection covering many different topics. The problem of missing semantical information about the images leads to great numbers of false matches because of misleading similarities in the visual primitives that are retrieved. T...

    Examining a program's state during execution is of major importance for software developers when analyzing an application for performance tuning or error detection. This demand for suitable analysis tools is further pushed by parallel and distributed programs, which process huge amounts of complex data. A solution to this problem is offered by visualization, such that even a large amount of data c... View full abstract»

    Communication through making marks is a fundamental human instinct. Humans have always used the act of drawing as a means to express ideas, emotions and to record actions. Currently, the discipline of drawing is being profoundly influenced, and perhaps forever changed, by the proliferation of new drawing media, technologies and diverse approaches to making marks through digital means. As such, the... View full abstract»

    Our goal is to deal with a non rigid surface, for example lubricant around a ball, interfaces between two fluids and so on. We then first describe how to approximate a movement and then how to interpolate such approximating functions. Finally we present two alternatives, global or local interpolation of the movements View full abstract»

    We describe an automatic surface reconstruction technique from a set of planar data points organised in parallel sections. The reconstruction employs skeletal implicit surfaces. Two key points in this study are: calculation of the 3D skeleton by establishing a correspondence between each paid of the 2D Voronoi skeleton of two neighbouring sections; and the use of a uniform field function necessita...

    Visualization of large urban complexes on the Web is a highly demanding task both from the networking and computational point of view. The whole three-dimensional model of a city is mostly too big to be downloaded in a reasonable time and to be stored in a memory of commonly used computers. This paper presents a scalable approach for subdividing an urban model into smaller parts. Dynamic loading a... View full abstract»

    The sensing and visualisation of 3D body surface information is being researched for clinical use in the radiation treatment of cancer, where accurate patient set-up and positional monitoring is essential. Where 3D measurement is based on the projection of structured light onto the patient it is neccessary to remove background detail prior to extracting patient surface topology. Rapid background c...

    The paper presents an interactive visualization tool, Archimedean Kaleidoscope (AK), aimed at supporting a learner's exploration of polyhedra. AK uses metamorphosis as a technique to help support the learner's mental construction of relationships among different polyhedra.

    Provides advanced visualization and interaction paradigms to support Web browsing through the intensive use of bookmarks, navigation history and best-of lists. Our approach is motivated by past studies of Web browsing patterns that proved the usefulness of such tools even though standard browsers provide very few interaction and visualization features for them. In this paper, we first motivate our... View full abstract»
