Declarative Approach of Inverse Lighting Problems

In the last years, a lot a research have been done in the field of inverse lighting (and, in a neighbouring domain: inverse rendering – or relighting). However the proposed tools for inverse lighting are not intuitive or are too limited. Our aim is to present a framework for a declarative specification of the lighting of a scene. The concepts and properties relevant to a qualitative description of lighting will be presented. In a next phase, their expression in fuzzy subsets theory will be done. To finally getting solutions to our problem, a new inverse lighting method will be proposed, especially fitted for CSP solving techniques.
