I was referring to you planet rendering system in general; the seams are
clearly visible in a few pictures, although the St. Helens image is very
good. Of course it also depends on the field of view. From your pages I
understood your techinque already uses intepolated transition zones between
hi and lo detail areas -- is it just that some images don't utilize this
feature (for example, earth_kilimanjaro1.jpg)?
How much pre-processing these images require? Can you have the global
height/texture data 'as is' on the disc, and have your modded pov-ray
selecting which parts to actually read into memory?

The kilimanjaro pictures are meant to illustrate that there are
different data sets combined so the visible transit is intentional. I
doubt there are visible seams in any of the other images at the size
they are on the website.

The images are just prepared in the required size and then used in
POV-Ray. I don't understand why you would need to modify POV-Ray for that.
