Abstract: This paper proposes a new mesh modelinc, scheme, called mesh fusion, based on three-dimensional (3D) mesh-based metamorphosis. We establish the attachment from a part of one mesh to a part of another with smooth boundaries, employing the traditional cutting and pasting operation in conjunction with a combination of meshes, applying the idea of 3D metamorphosis. We also offer an algorithm for adjusting two boundaries by usina the combination of three geometrical operations rigid transformation, scaling and deformation. Our schematic offers a computation time swift enough that the user can create various shapes with interactive speed.
