[gameprogrammer] isometric view in 3D

["Roger D. Vargas" <luo_hei@yahoo.es>]

Has somebody deal with the problem of implementing an isometric like 
view in Ogre or some other 3d engine?
I have achieved a look very close to old style games like Fallout, but I 
have a small problem. I want to provide camera rotation besides 
scrolling. With ogre it is trivial, I have a target node and a camera 
node. The camera node tracks target node, so I just have to rotate or 
translate target to get camera rotation and scrolling. The problem is 
that I thought that the correct camera angle for iso view was 45 
degrees, so I placed my camera at x,y,z, with y==z, but I found that 
such setup places the rotation point in some place on upper screen 
border instead of the screen center. if I reduce z, then the view 
becomes less isometric and more top-down like. Also tried approaching 
the camera but then I ran into troubles with near clip distance.
Can somebody give me an idea?
