Constraint-Based 3DS Isothetic Object Layout for Declarative Scene Modeling

—The aim of declarative modeling is to help the user to build a three-dimensional scene from a high level description. As underlying problems are combinatorial, constraints programming and related solving techniques are a neat and effective way to depict and to solve such problems. In this paper we focus on object layout in a three-dimensional environment that is usually a consuming time and tedious task. This study is restricted to isothetic 1 objects only. In this way, it is related to classical bi-dimensional space planning problems.
