The scripting node allows to perform operations on the data using a javascript-like syntax.

This node can be added to any other node, for example a Volume Node (i.e. to produce a volume rendering of the data).

A Volume Node for a vector field will visualize a volume rendering as following:

Since the data has 3 components the default visualization uses the 3 components as RGB channels.

If we want to evaluate and visualize the squared magnitude of this (three-dimensional) vector field the user can simply insert a scripting node with the following script:

output=
 ((1.0*input[0])*input[0]) + 
 ((1.0*input[1])*input[1]) + 
 ((1.0*input[2])*input[2]);

Where the input field represent the input data that enter the scripting node, the output represents the result of the computation.

The output will be a scalar field that will be rendered as following:
