Ok i have a question about the transpose of a matrix. I know it just swaps the columns around to become the rows like this: Matrix: [0,3,6] [1,4,7] [2,5,8] Transpose: [0,1,2] [3,4,5] [6,7,8] Ok and i was reading that if you wanted to know what the state of something was before it was transformed you do a transpose. So im wondering, does this mean what the vertex position was before it was, say for example translated somewhere? So if the position was<1,2,3> and it changed to <5,7,0> and all i have is that last coords and i needed the previous position, i would do the transpose on the matrix containing this vertex? Is that how that works or am i totally off? -SirKnight
