Abstract:
We present a new approach to lighting design for image synthesis. It
is based on the inverse problem of determining light settings for an
environment from a description of the desired solution. The method
is useful for determining light intensities to achieve a desired effect
in a computer simulation and can be used in conjunction with any
rendering algorithm. Given a set of lights with fixed positions, we
determine the light intensities and colors that most closely match
the target image painted by the designer using a constrained least
squares approach. We describe an interactive system that allows
flexible input and display of the solution.
