I am generating a render for a brush to be used in sculpture mode to detail the character. I am configuring the node editor and wanted to know. The normalize vector is used for what? What is the function of this normalize?enter image description here

Normalize (from the blender manual)

Normalizing a vector scales its magnitude, or length, to a value of 1, but keeps its direction intact.

Why do this for the Z-Pass?

The Z pass is the distance from the camera to the geometry in the scene for every pixel of the image. The camera is the 0 on the scale and the units used for its values are the working units set for the scene (blender units, meters, cm, inches, etc). The Z pass usually has values that exceed the 0 to 1 scale, and thus cannot be displayed as an image.

In order to visualize the information on the Z pass you normalize it so that if fits within the bounds of what can be displayed as an image (o to 1).
