Isometric Programming?

Im looking for any info people could provide me with on making a iso system like those on Transport Tycoon, and/or RollerCoaster Tycoon..

any info that people could provide would be great I have played around a bit with making the graphics in advance, but I was wondering if there was a way that I could just have textures then let the system reshape and draw them to the screen..

anything would be welcome..

um try my iso system just check my sig below...

or here if you have them turned off.

It doesnt support heights as such but its pretty extenable IMO. you can do what ever you want with the code.

Thanks I looked at your system already.. I will look into adding support for heights and such, if anyone else knows of a way to add in heights like rollercoaster tycoon or such let me know..
