.... surfaces between catenary curves [36] Barr, Terzopoulos, Platt and Fleisher have used discrete molecular components to model the elastic behavior of objects [22] Terzopoulos and Fleischer have extended the model mixing flexible and rigid components [33] and to simulate also inelastic behavior [32]. Many other techniques have been proposed to improve physically based deformations, as the methods based on constraints presented by Platt and Barr [23] and Metaxas and Terzopoulos [17] Approaches based on discretising the object into a number of particles, whose connectivity is maintained ....

....popularity of subdivision geometry, we have witnessed increasing number of applications in computer graphics using subdivision objects. The next few sections will cover several research that utilize subdivision geometry as a underlying tool. 5. 1 Interactive Modeling Since Terzopoulos et al.[90, 89] s research, a deformable model has played an important role in computer graphics, especially in animation. The deformable model is the geometric object that is governed by the Lagrangian equation of motion: ## # (r)# = f (r,t) 63) where r(p,t) is the displacement of p at time t, ....

....with regard to memory. The system handles individual patient data sets. While the model of the patient s bone structure and the patient s face is provided by a CT scan and a surface laser scan, respectively, the patient s soft tissue is represented by a mass spring system. Mass spring systems [22, 23] are not only used to model deformable soft tissue in surgical simulation environments, but they are also widely used to model other deformable objects. They have been applied to a variety of problems, such as cloth modeling [6, 10] and facial animation [18] Mass spring models assume a ....

....deformable models in graphics was pioneered by Terzopoulos et al. 32] The original work applied the Lagrangian equations of motion using a finite difference scheme to simulate elastic objects with regular parameterizations. This framework was extended to include inelastic behaviors [31], and to handle stiff rotating bodies using linearized equations [33] Following their introduction, physically based deformations were extended in many ways. Platt and Barr [24] introduced better constraint handling via Lagrange multipliers. Pentland and Williams [23] obtained realtime ....

....to achieve fast deformations. Baraff and Witkin [1] added non penetration constraints to this framework. Metaxas and Terzopoulos [21] combined global deformations with local finite element deformations. Implicit solvers are enjoying a renaissance in dynamic deformations. Terzopoulos et al. 32][31] used semi implicit solvers in their initial work. Baraff and Witkin [2] used a fully implicit scheme to greatly improve the speed and stability of cloth simulation. Desbrun et al. 9] used a semi implicit scheme to stabilize stiff systems. Hierarchical methods have also been used to speed up ....

....Fig. 15 shows a metallic flag animated using this method. For a rigid surface, explicit motions can be generated by a force field acting on the height vectors, thus deforming the texels. The force field can be for instance a Laplace field [WH91] a stochastic flow [SF92] or a mass spring [TF88] network connecting the tip of the height vectors. Fig. 16 left shows a lawn under the wind animated by this way (the force field we use is a mix of a moving periodic function and a stochastic function) Successive steps of a simple motion, such as oscillations of leaves in foliage, can be ....

....the surfaces. Transition between these representations are defined in [3, 6] The idea of simulating growth has been introduced in the scope of biological objects [28, 23, 22] The shape of elastic surfaces such as cloth material at equilibrium is generally obtained through physical simulations [25, 5, 2] although some geometric tools are also used to fake the physics [9] As D Arcy Thompson [26] suggests for natural objects, there are several possible approaches to explain a given shape. Interactive tools like Maya Artisan tm are convenient for the user, but they require the explicit design of ....
