[vtkusers] Vector field color and direction?

[Ragnarok]

How would you modify this existant example to not only be able to modify the
vector direction and size, but also it's color (so I can choose the color
based on for example the vector length)?

Would you add another set of imageData and then put the glyph2d color mode
to SetColorModeToColorByScalar ?

Even there, how can I add two set of inputData so I can have on one hand the
direction and size of vector, and on the other change their color?

the example in question :
