Evolving Character Controllers for Collision Preparation
m.s. thesis, 9/2006, oregon state university
robert rose, under the guidance of
dr. ron metoyer
Full dynamic control of physically simulated characters is the holy
grail of video games and other interactive applications. Recent
advances in the field have presented controllers that can handle the
balance and fall response after a collision. This thesis addresses the
development of a controller that handles the response before a
collision--reflexive posturing that protects the character from impact.
To solve this problem we present a technique that uses genetic
algorithms to optimize a pose controller based on analysis from a pain
measurement system. Applying our technique we develop collision
preparatory controllers that defend a virtual character in several
different styles from a variety of threats.
