Hi, I am using c# and managed directx, I am performing a translation on some vertices and I need to get where it moved it to. So can't I take the translation matrix and convert it somehow back into a vector. This is 2d. thanks

If you insist on saying "DUH", try to make a post that makes a little more sense

1) Shouldn't you already have the 2D vector that the translation matrix was built from?
2) If you multiply the vector in question by that translation matrix, the vector will get translated appropiately, so you don't need really need the 2D translation vector anyways.

I have two vertices that make up a line. then I have the whole location of the object, I transform the whole location. I'm wanting to know where the new points are so I can set the position of the two vertices. Not just the transformed location.
