VRP03_TITLE=Modeling Deformable Tissue
VRP04_DESCR=Goal:
   This project is aiming to explore the computationally efficient
deformable object models and their applicability to modeling deformable
tissue for surgery training simulators.

Describtion:
   A realistic deformable tissue model is desirable for surgery training
simulators.  These tissue models should be efficient and realistic in
estimating tissue behavior.  They should also be realistic in modeling
interaction forces.
   Most accurate way to model tissue behavior is to use finite element
models.  However these models are too slow.  The other choice is to use
somewhat simplified but realistic, computationally efficient models, if
possible.
   In this project I will try deformable models proposed by Terzopoulos
and Metaxas, and evaluate their applicability to the problem at hand.
   In the project, I will have a planar sheet of deformable tissue being 
manipulated.  The interaction will be through a passive 4 DOF joystick device.

Approach:
1) Familiarization with the development environment.
      The virtual environment will be programmed with OpenGL as it will not
    be structurally complex, and we will not need the extra functionality
    of high level programs that are available at the expense of decreased
    performance.
2) Adding deformable model
      Basic manipulation of deformable model (not interactive).
3) Adding user interaction
      Incorporating the 4 DOF Immersion joystick device with visual display
    of estimated interaction forces.
