Abstract

In computer graphics, easy-to-use tools for configuring lighting for 3D scenes are required by users. Following a perception-based lighting design framework, which models image quality using cognitively inspired objective functions, we present a new approach to lighting design which both: (1) allows the declarative specification of lighting; and (2) uses target scenes and images to facilitate intuitive and natural interactive control of the scene lighting. The LightOPex system enables users to select the desired lighting for a scene using exemplars in the form of 3D scenes and 2D images and uses the perceptual properties of these exemplars as target values in an initial optimization step.
