26: Light Interaction With Plants
Monday, Half Day
1:30 – 5:15 pm
Room 007AB
Physically and biologically based models of light interaction
with foliar tissues. This course provides implementation
details and background information that are often omitted
from publications. The emphasis is on scientific issues
that must be addressed to achieve a synthesis of realistic
and predictable plant images.
Prerequisites
Familiarity with rendering techniques such as ray tracing
and path tracing. Working knowledge of basic optics concepts
and radiometric terms. Experience with Monte Carlo methods
is helpful, but not required.
Topics
Spectrophotometric and goniophotometric measurements,
biological factors that affect scattering and absorption
of light by plants, models used in botany and remote-sensing
applications, and biologically based models aimed at rendering
applications. Advanced components of this course will
address accuracy and performance issues.
