11. 11 Variation - Stream-tube ► Generate a stream-line and connect circular crossflow sections along the stream-line

12. 12 Variation - Flow Volumes ► Instead of tracing a line - trace a small polyhedra

13. 13 LIC (Line Integral Convolution) ► Integrate noise texture along a streamline H.W. Shen
