The objective of the MoViTex project is to develop new models and techniques for the animation and simulation of virtual textiles. Its focus is on physical models that are based on classical continuum mechanics, but allow interactive simulations. Therefore, numerical techniques and the approximation of complex physical properties are the main areas of research.

Mass-spring and particle systems have been widely employed
in computer graphics to model deformable objects, because they
allow fast numerical solutions. In this project
we have established a link between these discrete models and classical
mathematical elasticity.
It turns out that discrete systems can be derived from a continuum
model by a finite difference formulation and approximate classical
continuum models well, unless the deformations are large.
The physical model used in the project is a particle system derived
from a continuum model.
This way we have gained insight into the way discrete systems work
and we are able to specify the correct scaling
when the discretization is changed.
Physical material parameters that describe materials in continuum mechanics
are also used in the derived particle system.
