But we don't want "perspective", we want "isometric". Isometric is 3D without the edge-warping perspective effects.
That's what I was wondering, but reading up on Isometric projection it seems like it does have a viewpoint as well, and hence perspective would seem to kick in. If I understand correctly, "isometric" just means a particular viewing angle.
From
http://en.wikipedia.org/wiki/Isometric_projection:
"In a similar way an isometric view can be obtained for example in a 3D scene editor. Starting with the camera aligned parallel to the floor and aligned to the coordinate axes, it is first rotated downwards around the horizontal axes by about 35.264° as above, and then rotated ±45° around the vertical axis"
Pasting in cities should be easy enough for someone with graphic arts experience, I would think.
Yeah, I'm hoping that this might work.
