A new technique for interactive vector field visualization us-
ing large numbers of properly illuminated stream lines is
presented. Taking into account ambient, diffuse, and spec-
ular reflection terms as well as transparency, we employ a
realistic shading model which significantly increases quality
and realism of the resulting images. While many graphics
workstations offer hardware support for illuminating surface
primitives, usually no means for an accurate shading of line
primitives are provided. However, we show that proper illu-
mination of lines can be implemented by exploiting the tex-
ture mapping capabilities of modern graphics hardware. In
this way high rendering performance with interactive frame
rates can be achieved. We apply the technique to render
large numbers of integral curves in a vector field. The im-
