Abstract
The construction of geometry from scattered data brings together the
problem of data approximation and the problem of geometric design. Most
specific algorithms for scattered data approximation have limited
flexibility for incorporating design issues from an engineer's point of
view. Such considerations have to be offered the engineer via flexible
software systems. Siscat (The SINTEF Scattered Data Library) is an
object-oriented toolkit with the aim of providing the engineer with
tools for building geometries that approximate data and satisfy his
intuition as well. The present paper discusses some basic design issues
of Siscat, and illustrates these concepts on a model problem taken from
cartography.
