A Data Structure for Representing and Efficient Querying Large Scenes of Geometric Objects: ,* Trees statement still holds if we demand that the cluster radii, which appear on a path from the root down to a leaf, should generate a geometrically decreasing sequence..We report on extensive experimental results which show that .* Trees support a large variety of proximity queries by a single data st

Automated Feature Recognition and its Role in Product Modelling,ature definition language which will permit the integrated system to be configured flexibly to meet the precise requirements of any organisation using it. This will also have strong implications on the development of standards for the transfer of CAD information between different systems.

Functionality in Solids Obtained from Partial Differential Equations,quation on to some simple object in parametric space, typically a cuboid. The isoparametric surfaces within the solid define a mesh system and it is shown how various features of the chosen PDE may be used to modify the mapping, and in particular the generated mesh, and thus facilitate analysis of m

Featuremodelling with an Object-Oriented Approach,-oriented mechanisms are utilised to define part structure and behaviour models. The mechanism is part of an ‘application specific modelling platform’ or ‘framework’, which allows application software to interact with the CAD/CAM system on a high-level and to capture, evaluate and store the design i
