Vector Field Visualization using Anisotrop Diffusion

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 software.
