Nowadays, the available tools for lighting design are limited in scope
and inappropriate for interactive or creative use. In this paper, we present
a different approach to the lighting design problem – a new methodology
that includes the geometry and materials of the scene, the lighting design
goals and a computational search for lighting solutions. The objective
is to improve and shorten the lighting design cycle. The most common result
is a set of luminaire characteristics that maximises the attainment of
the user defined lighting goals. These goals may include different kinds
of constraints or objectives. We also discuss the use of optimisation in
lighting design, describe an algorithm that implements the proposed methodology
and present several examples.
