Ok, been a while since i covered arrays in highschool.

Now i have some arrays, id like to be able to perform some functions on them. For example move/rotate/scale

Ok. so i have 3 arrays
an array for the vertex number, an array for x position and an array for the y positions.
Is there an easy way to translate these arrays ready to move the vertexes ot the new positions?
Can i choose to scale from the center of my selection etc?

Look through this page:
http://gpwiki.org/index.php/3D:Matrix_Math
It covers a lot of how to handle matrices for 3d transformations.
Here's another one:

Doing things like scaling from certain points requires manipulation of the Matrix, but it's definitely doable.
