English abstract:
It has been pointed out repeatedly that spatial operations must be
extended to include support for 3D and moving objects. The
attempt to code by hand each spatial operation for each data type
(e.g., static 2D, moving 2D, static 3D, and moving 3D) is
forbidding and has led to specific solutions for particular
purposes. In this paper, we have advocated an operationindependent
approach to extend 2D spatial operations to 3D and
moving objects. The approach is based on implementation of the
concepts of n-dimensional geometry through definition of
transformations between domains called "lifting". It is explained
via some sample spatial operations and then the implementation
results for convex hull computation are represented.
