Declarative modeling in computer graphics

Abstract

A review of declarative scene modeling techniques is presented in this paper. After a definition of the purpose of declarative modeling, some existing declarative modelers are classified according to the manner to manage imprecision in scene description. Then, a concrete application is described, using constraint satisfaction techniques in the framework of Declarative Modeling by Hierarchical Decomposition (DMHD). Machine-learning techniques, applied to DMHD are presented as well. The aim of this chapter is to present declarative scene modeling and to show its importance for a really computer aided design in image-based information systems, as well as some drawbacks of this modeling technique. Some suggestions for possible future extensions of declarative modeling are also given. © 2009 Springer-Verlag Berlin Heidelberg.
