The picture above is a snapshot of a vector field animation
generated by the equation v = -yi + xj
+ (y-x)k
using VRML (Virtual Reality Modeling Language) in
which computer coding is translated by an Internet browser
in order to view items in a virtual environment.
If you have
a VRML plug-in for your browser, you can click on the
vector field animation
and view it from all angles to examine its properties. A
second example
is based on the equation
v = yi + xj + (y-x)k.
