  POVghanistan/POVEarth: now with Melody's smooth triangles macros!

Hi(gh)!

I succeeded in implementing Melody's macros to my POVEarth/POVghanistan 
script, so I can provide you with a first test rendering... but as 
generating smooth triangles and consecutively entire mesh2 objects 
entirely with POV-Ray SDL is abysmally sloooooooooow, I had to scale the 
altitude data resolution from originally 3600 by 3600 down to 100 by 100 
measuring points - and even this took 37 minutes. Generating the mesh2 
in the original resolution would take a whopping 33.3 days!

This has to be accelerated, of course - and I'll do this by converting 
both Melody's code for generating the normals and my code for generating 
the mesh2 object to C or C++. When this works, I'll start generating 
pre-calculated mesh2s from ASTER ASCII data tiles for the whole land 
surface of Earth and provide them for download on my webspace! So 
finally after 14 years (remember my posting from September 11, 2005?), 
the POVEarth project starts to gain momentum...

See you in Khyberspace!

Yadgar
