In this paper, we explore the problem of interactively mauipulating plant models without sacrificing their botanical accuracy. The primary technical contribution of the paper is a method for interactively manipulating plant structures using a inverse-kinematics optimizatitin technique. The branches of the plant are endowed with flexural and torsional stiffnesses, and these are used in the IK optimization. We demonstrate our approach with several examples of plant models arranged in this fashion.
