Bezier Lines and Matrix Transformations

Hi Ken,

Yes, I'm fairly familiar with Vector math. However your explanation was slightly confusing. Could you maybe try to go into a little bit more detail? Also, what do you mean by displace? I think I got what you meant, however if I did, then take a look at what I get (there's just 2 rails, I haven't even tried 3 yet):

Thanks again,
Nick Small.
