Using the XYZ coordinate system?

Hi all,
I'm completely to grips with the XY coordinate system so feel I should progress up the ladder to success (well it sounds good :D). Put in simple terms, I would like to learn about using the XYZ coordinate system. Can somebody maybe give me some info and even supply me with a URL to a tutorial? I would be very grateful.

Thanks :)

3D coordinates system is just extrapolation of 2D. Instead of 2 axis there are 3, instead of 2 values a vector consists of 3. What do you allready know?

Hi Kedaman,
I know all that stuff but where I am puzzled is when you start moving away from an object. How much smaller does it get when you are X (being any number) distance away etc. And when you move away from an object, does is get slightly higher or lower etc. There are questions, which I'm unsure of.

You are talking about perspective right? An object get's smaller proportional to the distance. What are you intending to do?

Well, I'm not doing anything special. I have a 3D box floating in the middle of nowhere. I want be able to spin it around. You see, it's nothing big, but I have to start somewhere.

Oh, it's big enough =P. You are going to have much fun learning about Matrices. 3D graphics are very math-heavy. In a nutshell, To draw something on screen, you must transform the points from 3D (XYZ) space, into screen (XY) space. This is done with a perspective projection matrix (if you are doing perspective rendering, there are several types of projection matrices). For each vertex in an object, it is multiplied by this matrix, and then you can draw a line from each vertex to the others.

I'm not sure where you can find a tutorial on this stuff, but if you are really interested in VB graphics, you might want to look into the book "Visual Basic Graphics Programming". It explains all of this stuff, and FAR more.

Thank Zaei, I'll have a look for that book. :)

no need for transformation (yet)
How does the box spin? how does it move?
