Surface Modelling with Guaranteed Consistency - An Object-Based Approach
There have been many interpolation methods developed over the years, each with their own problems. One of the biggest limitations in many applications is the non-correspondence of the surface with the objects used to support it - usually a set of arbitrarily distributed data points, This is due to the metric methods used to define both the zone of influence of a data point and the set of data points used to estimate surface properties at intermediate locations. Most methods are coordinate system oriented, not object oriented. We describe here an object-otiented approach, in the sense that the data objects themselves form the spatial structure used for interpolation. This has the primary benefit that the surface is described in terms of this structure, permitting easy correspondence between the surface and data values. In addition, the spatial objects used are not restricted to points, but may include more complex objects - currently composed of line segments. The structure used is the...
