Streamlines
Jean M. Favre
11
Variation - Stream-tube

• Generate a stream-line and connect circular
  crossflow sections along the stream-line

12
Variation - Flow Volumes

• Instead of tracing a line - trace a small
  polyhedra

13
LIC (Line Integral Convolution)

• Integrate noise texture along a streamline

Challenges Non-spatial Data
Vertical velocity vs. velocity
X-coordinate vs. viscosity
