Abstract
Line Integral Convolution (LIC) is a common approach
for the visualization of vector fields. It is well suited for visualizing
the direction of a flow field, but it gives no information about the
orientation of the underlying vectors. We introduce Oriented Line Integral
Convolution (OLIC), where direction as well as orientation are encoded
within the resulting image. This is achieved by using a low frequency
input texture and a ramp like (unisotropic) convolution kernel. This
method can be animated, whereby the computation of so called pixel traces
fastens the calculation process. In the result section various OLICs using
simple and real-world vector fields are shown.
