  Binary Meshes?

Still aiming at POVEarth/POVghanistan (and also high-quality renderings 
of other Solar System bodies) - but currently, there is a bottleneck 
when it comes to generating "spherical" (i. e. following Earth's 
curvature) mesh2s from 16-bit (or whatever format) heightfields!

The Japanese ASTER mission elevation tiles have a resolution of 3601 by 
3601 measuring points (i. e. pixels in a heightfield generated from 
these data) - but even with 16 GiB of RAM, I had to decrease the 
resolution to 2600 by 2600, otherwise POV-Ray would crash.

Of course this is because POV-Ray generates full ASCII code rather than 
(like with heightfields) binary data to internally represent the mesh2 

Have there ever been any attempts to write a patch to make binary meshes 
feasible with POV-Ray?

See you in Khyberspace!
