Hello All

This is not A Tech support Question, But You can
Answer if you wish & I would be very Grateful.  

I wonder if Anyone could enlighten me on a few Questions 
that have recently been Nagging my Overloaded Grey Matter. 
But first some background info.   

I am currently working on a Map Editor for a 3d World.
The World Objects (WO) (Only Floors & Walls supported at
present) are made up of Textured Quads (at last I sussed it):-). 
The Objects are  initially placed in the World via translation.
The World is currently scrolled  around in 8 directions by 
modifying the x y z  positions of the Objects. 
At present The Game engine could support a game like 
"Crash Bandicoot" or "Lone Soldier". i.e. (the world doesn't
 rotate in the direction of the viewpoint of the player character (PC) ) 
before I begin building functions around this rather limited engine
I would like to ask a few questions.

1. When coding a game of this type is it best to-: 
(a) Scroll the WO  & leave the PC  x y z co-ords alone ?
(b) Move the PC & Viewpoint & leave the WO xyz co-ords alone?
At present I use (a).

2. How do games like Tomb Raider Doom ect  Rotate  the world in the
direction
of the PCs view point?
a) Rotate the WO in relation to the position within it?
b) Clever use of camera Angles?
c) Both?
d) put your $2 worth here

3. Z buffering Has any one any good algorithms for this?
 
4. Could anyone point me in the direction of any specific Net Resources
 i.e. FAQs, WWW, FTP ect that explain any of the Above?

5. Can Yaroze Handle a game of this Type? 
 
I am aware that many of these Questions may be asking  for a little to
much
info But if you don't Ask, You wont get any Answers. 

Thanks in Advance
