%X In this paper, a boundary element method is first applied to real-time animation of deformable objects and to simplify data preparation. Next, the visible external surface of the object in deforming process is represented by B-spline surface, whose control points are embedded in dynamic equations of BEM. Finally, the above method is applied to anatomical simulation. A pituitary model in human brain, which is reconstructed from a set of anatomical sections, is selected to be the deformable object under action of virtual tool such as scalpel or probe. It produces fair graphic realism and high speed performance. The results show that BEM not only has less computational expense than FEM, but also is convenient to combine with the 3D reconstruction and surface modeling as it enables the reduction of the dimensionality of the problem by one.
