Abstract
A major problem challenging opera designers is the inability to
coordinate lighting, projection systems, and set designs in the
preliminary planning phase. This talk will present new
computer graphics techniques that provide set and lighting designers
with the opportunity to evaluate, test, and control opera designs
prior to the construction of full scale systems and installation
of the lighting apparatus. The techniques include tools for
light source specification and simulation, projected scenery,
time-dependent intensity control, and inverse lighting design.
Specifically, the talk will focus on the following topics:
- a light source specification component that consists of tools
for assigning light source attributes and simulating their
effects with radiosity techniques.
- a projection approach that simulates the optical effects of
scenic projectors and solves the distortion problem that
comes with angular projections.
- methods for synthesizing images of complex, time-dependent
lighting in scenes with fixed geometry.
- an approach to inverse lighting design for image synthesis,
based on the inverse problem of determining light settings
for an environment from a description of the desired solution.
The techniques are demonstrated with complex models based on
actual stage sets from New York's Metropolitan Opera.
