“Normalize” procedure in C#

Could someone explain to me what the normalization procedure for 3D surface mesh in C# is?

In a reference book, there is a line as follows :

The GetNormalize method is used to map the region of your surface into a region of [-1, 1], which gives you a better view on your screen.

You calculate the box bounding your surface mesh, get the longest side of the box and scale everything down by that value. The result will be [0,1] for that side and [0,<1] for the rest.

If you need [-1,1], you double everything and substract 1, getting [0,1]*2-1=[0,2]-1=[-1,1].
