An animation system for rigid and deformable models
We describe a system for the animation of rigid and deformable models. The system uses the approaches from elasticity theory for animating the models. Two different formulations, namely the primal and the hybrid formulations, are implemented so that the user could select the suitable one for an animation depending on the rigidity of the models. Collision of the models with impenetrable obstacles and constraining model points to fixed positions in space are implemented for use in the animations. © 1993

Physically-based animation of elastically deformable models
Ankara : Depatment of Computer Engineering and Information Science and Institute of Engineering and Science, Bilkent Univ., 1994.Thesis (Ph.D.) -- Bilkent University, 1994.Includes bibliographical references leaves66-71Although kinematic modeling methods are adequate for describing the shapes
of static objects, they are insufficient when it comes to producing realistic animation.
Physically-based modeling remedies this problem by including forces,
masses, strain energies, and other physical quantities. The behavior of physicallybased
models is governed by the laws of rigid and nonrigid dynamics expressed
through a set of equations of motion. In this thesis, we describe a system for
the animation of deformable models. A spring force formulation for animating
deformable models is also presented. The animation system uses the physicallybased
modeling methods and the approaches from elasticity theory for animating
the models. Three different formulations, namely the primal, hrjhrid, and the
spring force formulations, are implemented so that the user could select the suitable
one for an animation, considering the advantages and disadvantages of each
formulation. Collision of the models with impenetrable obstacles and constraining
model points to fixed positions iii space are implemented.Güdükbay, UğurPh.D
