Abstract
Many of the most interesting behaviors in the biological world have
to do with interactions between species. The predator-prey interactions among
aquatic organisms is an interesting part of the natural world which has not
been seen much in computer animation. This paper explores the interaction
between various sea anemones and the starfish Dermasterias imbricata. Although
a simulation between a specific sea anemone, Stomphia coccinea to Dermasterias
imbricata was created, an approach was taken such that different anemones can
with minor parameter changes be used to replace S. coccinea. The animation was
created using a parametric keyframe approach of procedural models. The
anemone and starfish were modeled using the Blob Tree. The implicit model
within the system is defined as a hierarchical composition of multiple
objects. Using a hierarchical construction of the model, we can refine the
model locally and deform it globally while maintaining the integrity of
surface details.
