Need help identifying operator

  1. Aug 16, 2008 #1
    I am going through some papers on computer graphics because I'm implementing a 3D engine and have come across and equation I don't recognize. I've looked in every linear algebra book on vectors and matrices I have but had no luck whatsoever.

    equation goes like that, sorry for bad formatting:

    || (x,y,z)T ||2

    I thought this was absolute value of vector(length), but since it doesn't do what it's supposed to visually, I have my doubts. Does anyone recognize it and how do I calculate it?

    That is the ordinary length of a vector: square root of the sum of squares of components. I don't know what it is "supposed to do" so I don't know whay you have doubts.
