Exporting from Terragen to POV is quite straightforward, but a bit tedious
(at least for me, maybe there's a better way...):
In Terragen:
- generate a nice height field (Default settings)
- select a color map (surfmap)
- Save the height field as '8 bit raw' (more on this later...)
- Set the camera at a very high altitude, looking directly down, full zoom,
make sure you see all the landscape
- Turn sky and shadows off and render the picture, this generates a bitmap
that will be used as 'image_map' in POV.
In a picture processing program that can handle the 'raw' format (for
example Paint Shop Pro):
- load the 'raw' height field you saved from Terragen
- save as .tga
In POV:
- Start with a 'Basic scene...', remove the plane and sphere
- Insert the following (suitably edited):
height_field
{tga "TheHeightFieldImage.tga"
smooth
hierarchy on
pigment
{image_map
{sys "TheColorBitmap.bmp" once interpolate 2}
}
translate <-.5, -.5, -.5>
scale <17000, 1750, 17000>
}
The scale is of course not exact, but choosen to match my test case (a car
in the Rockies?):

(Quite a bit of fiddling in POV to get the car to the right place!)
It would be nice with a shorter path from TG to POV!
