#!CSeaGreen #!N #!Rtstmln2 Streamlines #!N #!EC #!N #!N If
your 2-dimensional data set consists of vectors, you can create streamlines
that trace the path of a massless particle in a vector
field. #!N #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1.
Open and execute visual program .../Streamlines2D.net. The image is a set
of streamlines that follow a wind field over the surface of
the earth. #!N #!I30 #!N 2. Change the number of streamlines
by changing the value of the #!F-adobe-times-bold-r-normal--18* density #!EF parameter in
the configuration dialog box of the #!F-adobe-times-bold-r-normal--18* Sample #!EF tool. #!N
#!I30 #!N 3. Reexecute the visual program. #!N #!I0 #!N #!EF
#!N Note: Streamlines can be generated in other ways as well.
For example: #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1.
Pass a list of 2-dimensional positions to the #!F-adobe-times-bold-r-normal--18* start #!EF
parameter in the #!F-adobe-times-bold-r-normal--18* Streamline #!EF configuration dialog box by either:
#!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N a. inserting a
#!F-adobe-times-bold-r-normal--18* VectorList #!EF interactor stand-in (from #!F-adobe-times-bold-r-normal--18* Interactor #!EF in the
categories palette) into the visual program, and connecting it to the
#!F-adobe-times-bold-r-normal--18* start #!EF parameter tab of Streamline #!F-adobe-times-medium-i-normal--18* or #!EF #!N
#!I30 #!N b. typing the start positions in the configuration dialog
box for #!F-adobe-times-bold-r-normal--18* Streamline #!EF . #!N #!I0 #!N #!EF #!N
#!N #!N #!I30 #!N 2. Use the #!F-adobe-times-bold-r-normal--18* Grid #!EF tool
(from #!F-adobe-times-bold-r-normal--18* Realization #!EF in the categories palette) to create a
particular set of start positions. Any field that contains positions can
be used as the starting point for streamlines. #!N #!N This
sample visual program contains a Grid tool. Connect it to the
#!F-adobe-times-bold-r-normal--18* start #!EF parameter tab of Streamline. It generates a 3
* 3 grid of points. Modify it to create a 10
* 3 grid of starting points. #!N #!I30 #!N 3. Use
the #!F-adobe-times-bold-r-normal--18* Probe #!EF tool (from #!F-adobe-times-bold-r-normal--18* Special #!EF in the
categories palette) to select starting points in the Image window. #!N
#!N This sample visual program contains a Probe tool. (Compute is
used to make the value of the probe point 2-dimensional.) Connect
the output of Compute to the #!F-adobe-times-bold-r-normal--18* start #!EF input tab
of Streamline, and then move the probe (i.e., enter cursor mode,
using the #!F-adobe-times-bold-r-normal--18* View Control #!EF dialog box). #!N #!I0 #!N
