    With the advent of global competition, greater numbers of organisations require collaborations with others. Concurrent engineering can provide a highly effective framework for this collaboration. A distributed object oriented concurrent engineering system (DISCS) focuses on the communication of data between the members of a distributed project team. Conceptually the communication is the enabling f... View full abstract»

    Java3D is an application-centred approach to building 3D worlds. We use Java3D and VRML to design a prototype WWW-based 3D Hotel Browsing system. A Java3D scene graph viewer was implemented to interactively explore objects in a virtual universe using models generated by a commercial computer graphics suite and imported using a VRML file loader. A special collision prevention mechanism is also devi... View full abstract»

    A rational cubic spline with a family of shape parameters is discussed from the viewpoint of its application in computer graphics. It incorporates both conic sections and parametric cubic curves as special cases. The parameters (weights), in the description of the spline curve can be used to modify the shape of the curve, locally and globally, at the knot intervals. The rational cubic spline attai...

    Delaunay triangulation is well known for its use in geometric design. A derived version of this structure, the Delaunay constrained triangulation, takes into account the triangular mesh problem in presence of rectilinear constraints. The Delaunay constrained triangulation is very useful for CAD, topography and mapping and in finite element analysis. This technique is still developing. We present a... View full abstract»

    The aim of occlusion culling is to cull away a significant amount of invisible primitives at different viewpoints. We present two algorithms to improve occlusion culling for a highly occluded virtual environment. The first algorithm is used in the pre-processing stage. It considers the combined gain and cost of occluders to select an optimal set of occluders, called minimum occluder set, for each ... View full abstract»

    Architects and other designers use diagrams to visualize the process of product analysis and synthesis. The paper outlines a new pictorial representation tool that helps designers visualize the process of composing and classifying their final products. Finite state automata (FSAs) are used in the context of formal languages as recognition devices. In this sense, they complement the synthetic devic... View full abstract»

    Virtual reality techniques are being used to support the development of unmanned space probes intended to land on other planets in the solar system. These planetary landers will operate autonomously during landing and will use vision for navigation and guidance down to a safe landing spot. Suitable vision techniques have been developed but must be extensively tested on realistic test surfaces. A s... View full abstract»

    Models for visualization are important, helping the developer and user to understand the visualization process; to follow the connections and the data paths through the system; and to reference and compare the functionality and the limitations of different systems or techniques. Display models specifically classify the data by what type of output can be created. Bertin, J. (1962) described a symbo... View full abstract»

    In computer graphics, aliasing is a problem which is always present when discrete elements are mapped to continuous functions or vice-versa. Although there is no general solution for this kind of problem, there are many techniques that aim at reducing the effects of aliasing. The article first discusses how interpolation methods are usually applied in order to correct this problem and shows the li... View full abstract»
