Affective scene generation

ABSTRACT

A new technique for generating virtual environments is proposed, whereby the user describes the environment that they wish to create using adjectives. An entire scene is then procedurally generated, based on the mapping of these adjectives to the parameter space of the procedural models used. This mapping is determined through a pre-process, during which the user is presented with a number of scenes and asked to describe them using adjectives. With such a technique, the ability to create complex virtual environments is extended to users with little or no technical knowledge, and additionally provides a means for experienced users to quickly generate a large, complex environment which can then be modified by hand.
