Image-Based Lighting
Sunday, Half Day, 1:30 - 5 pm
Petree Hall C
A
survey of recently developed techniques for realistically
integrating computer-generated imagery with live-action
photography that use measurements of real-world lighting
to illuminate CG objects. The techniques are illustrated
with detailed breakdowns of the animations "Rendering
with Natural Light" and "Fiat Lux," shots
from recent feature films, and examples of how they are
used in commercial packages such as LightWave 3D. The
course concludes with an overview of techniques to extend
image-based lighting to people and objects in the real
world.
Prerequisites
Basic knowledge of or experience with modeling and rendering
in traditional modeling and rendering packages (for example
3D Studio Max, LightWave 3D, Maya, or Softimage). Familiarity
with basic traditional CG lighting and compositing. No
advanced ray-tracing or global illumination knowledge
is assumed.
Topics
High-dynamic-range photography, lighting acquisition,
image-based lighting and com-positing, real-time techniques,
and ongoing research in illuminating real people and objects
with sampled light. How the techniques are used in actual
productions and with particular software packages. Basic
principles of light reflection and global illumination.
