| | I still don't fully understand it... :(
Is there a website where I can learn the basics of vectors, matrices and transformations? | |

| | I had not seen that link. I just read through it and fully understand. Thanks for the help there. Maybe this chapter should be updated with a link to that explanation.
Awesome tuts Riemer. | |

| | Hello, I was wondering about this line in the text..
----------
This is what we need: if the X axis is pointing to the right and the Y axis is pointing down, the Z axis is sticking out of the screen!
----------
I'm confused because I thought XNA 3d coordinate system was right handed. It would mean z-axis points into the screen. | |
