Abstract

Nowadays, VRML has grown to a Web3D standard. But there is still a lack of high-level tools to help a VRML designer in his/her conception of a virtual world (in the same way as declarative modellers make easier the conception than classical modellers). The purpose of our work is to allow a VRML designer to specify an ambiance in a declarative manner. The method described in this paper takes into account imprecision and uncertainty in ambiance descriptions with the use of fuzzy subsets theory. With this framework, the designer can introduce some modifiers (like: “very little” or “extremely”) in his/her objectives in order to refine the wished ambiance. Two characteristics have been studied: the foggy aspect and natural lighting. Natural lighting is introduced with the aim of a natural description: the lived time.
