For that new algorithms in domain decomposition for fluid flow problems and the use of distributed systems have been designed. Current research also focuses on transportabilty and efficiency of scientific applications on parallel machines focusing on sparse matrices methods and parallelization. New free form surfaces using paving algorithms and plate type energy are being implemented. Level sets are being used for optimisation of geomtric growth problems . Finally new solid modeling tools are designed as the necessary link between CAD and mesh generation.
User interaction is one of the most important issues in the success of computer software.
We treat the unique issues arising in geometric interaction. We developed the concept of a Direct Manipulation Device, which enables uniform treatment and elegant implementation of direct manipulation geometric interaction techniques. We apply the concept to constraint based modeling, graphics image processing, and modeling with splines and polyhedra. The focus of computer graphics today is in visual communication. We develop methods to increase the effectiveness of computer generated imagery.
