== Overview ==

The Normalise vector node takes a vector as input and outputs the same vector with a magnitude (length) of 1. It does this by dividing the vector by its length so that its new length becomes 1. This is often referred to as a unit vector. Essentially, it rescales a vector to a length of 1, without changing its direction.

The following example is for illustrative purposes only. An EXR image supplies vector data to displace the planet surface. The vector data is first passed to a Normalise vector node prior to being passed to a Vector to colour node because some of the vector values will exceed the visual range, 0 to 1 or sRGB 0 - 255. Once normalised, the vector data is then converted to colour via the Vector to colour node.
