Hi Riemer,

Great Tutorial. I just thought I would let you know a few things that threw me whilst reading this chapter.

They are minor and please don't think i am picky.

You say "The first parameter defines the position. We position it 30 units above our (0,0,0) point, the origin."  Hoever you position it forty units above.

Matrix viewMatrix = Matrix.CreateLookAt(new Vector3(0, 0, 40), new Vector3(0, 0, 0), new Vector3(0, 1, 0))

In the chapter "Drawing a triangle" you specify the color of the vertices as Red,Green,Yellow but then change it Red,Yellow,Green in this chapter. I was confused because I only changed the float arguments and didn't replace the code and wondered why my traingle was not orientated like yours.

I repeat these are minor points but maybe if you change them other newbies will be less confused.

Thanks for the comments! Indeed, especially the first chapters mustn't scare away interested visitors because of silly mistakes.

This pc doesn't have xna installed however, so I was only able to fix the first comment.

I also wanted to add as a simplifier that your camera and UP vectors can be set using Vector3.Zero and Vector3.Up which are part of the Vector3 intellisense.

Thanks for the addition, but I'm not sure if it would be wise to do that... I think it's better to show which vectors we're using. The .Up also always equals (0,1,0), which is not always what you'ld want. I think it can cause a lot of confusion.

Just curious why you don't like using the Y-axis as up, and in the next series are using the Z-axis. This can be somewhat confusing, at least it is to me.
