Creating Evenly-Spaced Streamlines of Arbitrary Density,all density of the image. We show that our method produces images of a quality at least as good as other methods but that it is computationally less expensive and offers a better control on the rendering process.

Efficient and Reliable Integration Methods for Particle Tracing in Unsteady Flows on Discrete Meshed error monitoring. A second aspect of this work is the treatment of stiff problems. Stiffness occurs m flows with strong shear deformations or vorticity. To detect stiffness in a given flow field, the Jacobian of the velocity field is analyzed. Implicit integration methods are used to handle stiff systems of ordinary differential equations.

,Efficient Visualization of Large—Scale Data on Hierarchical Meshes, to supply a set of element access routines as an interface to his specific data structures. As no extra storage is required, also large, economically stored computational grids can be handled on workstations with moderate local memory. Significant examples illustrate the applicability and efficiency on different types of meshes.

Simulation of Differential Interferometry and Comparison with Experimental Results,heoretical models of these objects are discussed. The concept of an interactive visualization system for the analysis of phase objects is presented and finally some results allowing a comparison between experimental and simulated interferograms are shown.

Parametrizable Cameras for 3D Computational Steering,ner. Each view can be coupled to objects present in the interface, parametrized to (simulation) data, or adjusted through direct manipulation or user defined camera controls. Although our focus is on 3D interfaces for computational steering we think that the concept is valuable for many other 3D graphics applications as well.
