Recently, I started building mesh2s following Earth's curvature from 
SRTM Earth elevation data (3 arcseconds per data point)... when 
rendering those mesh2s, I found some strange artifacts (gaps between 
triangles, see image on p.b.i.) which probably resulted from floating 
point inaccuracy (the scale I used is 1 POV unit = 1 kilometre).

As Christoph Hormann, as he writes on his website, apparently uses a 
kind of (self-written?) conversion tool, I thought that converting my 
mesh2s to isosurfaces possible could solve the gaps problem...

See you in Khyberspace!
