Forgive me if this isn't well phrased, it's been a while since I've done any maths!

I have a 2d image whose central point is located at the world origin, and it is in the plane $z = 0$.

If I rotate the image $\alpha$ degrees about the $z$-axis and $\beta$ degrees about the $x$-axis, how can I calculate the normal vector to the plane the image is now on?

Thanks in advance.

    I don't think I described it well enough - I'm sure there needs to be three changing components here. I need to be able to move the image in the direction it is facing. If you imagine multiple flat images all originating from the same source point, all tilted slightly upwards at the same angle, but all facing in different directions relative to the z-axis, and I need them to move in the direction they are facing. So you can imaging them all moving in different directions, but pointing at the same angle upwards. If I keep α = 0, then (0, -1, 1.73) gives me the correct result...2012-08-14
