Abstract:

In this thesis, I modeled, for the purpose of producing animated sequences, a small crabapple tree. The tree was measured to determine both its geometry and and its dynamic properties. This data was used in conjunction with various physical models to generate a 102 degree of freedom simulation. This simulation captured interesting aspects of trees: leaning away from the wind, and swaying. The visual result was lacking because of the difficulty of tuning the servo constants and the lack of leaf motion.
