Hi(gh)!
Obviously, I once more have messed up my POVEarth code - when I run my
mesh2 generator (attached here), a strange error shows up:
"File 'mesh2writer.pov' line 287: Parse Error: Expected 'string', End of
File
found instead
Fatal error in parser: Cannot parse input."
Though the generated mesh2 scripts look correct, whenever I render a
scene containing them, I see no terrain relief, but only ocean...
For better understanding, I also attached a (small) mesh2 script
generated with the mesh2 generator.
See you in Khyberspace!

tried to have a look, the mesh data appears to parse ok, however, am struggling
with the dimensions and trying to get the camera set up. it would help if you
could post a small scene file that just includes that tile and displays it.

cheers.

same here. I inserted, after line 211, a line which simply subtracts from the Y
axis of 'Cam_oceanfloorpos', going from -2.5 to -2.6 the view changes.
no real idea, to be honest. (had thought about height_fields, their adjustable
water_level :-)) and absolutely no idea why you see the EOF error message, the
code looks kosher.
regards, jr.

I added line 253 as:
translate Cam_Pos/2
then
I changed line 281 to
location Cam_Pos*2
Your tile is not positioned properly.

I tried out your suggestions... and the result is quite weird, as you see:

Indeed.
I would suggest either getting rid of your planet entirely for test renders, or
at least give it a transmit value so you can see below the surface.
Create a macro that will give the min_extent and max_extent of your tile, and
calculate the approximate surface normal. You could then "draw" a cylinder
from the planet center to the center of the tile, and a cone from a [large]
fraction of the camera location to the center of the tile, so you can always get
a bearing on it.
But at least you see the tile and know its approximate location.

I really have no clue how to do this - and I can't look it up, as is
seems not to be included in the POV-Ray 3.7 doc!

#declare Obj = union {

#local Min = min_extent (Obj);
#local Max = max_extent (Obj);
#local Center = (Min+Max)/2;
