Vector fields are normally the result of computer
simulations, or measurements, done in a number of
scientific fields. This can be in fluid dynamics,
meteorology, medicine, climate modeling and oil
exploration, just to mention a few. To be able to
understand and interpret these data, we normally
need to transform them into images. A good image
will hopefully also help us in obtaining new insight
into the underlying physics.
To display an image of a 2D vector fields is fairly
simple. However, meaningful images of 3D fields are
much more challenging to produce, as cluttering and
occlusion often obscure important details.
In this work we present a techniques that
solve some of these issues, and produce high quality
images and animations of 2D and 3D vector fields.
This is done by solving a partial differential
equation (PDE) for anisotropic diffusion, and
displaying the results in modern Volume Rendering
