Hi(gh)!
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
object.
Have there ever been any attempts to write a patch to make binary meshes
feasible with POV-Ray?
See you in Khyberspace!
