Meanwhile, I at least downloaded all ASTER HGT DEMs of Georgia and the
surrounding areas - as I plan to do animated high altitude flights (for
example from Tbilisi to Batumi), I have to include all data tiles up to
500 kms from the camera position, i. e. well into Russia, Turkey and Iran.
To keep RAM usage low enough, with increasing distance from the camera,
the tile data resolution decreases, so I generate each mesh2 in a 3601
by 3601 (full), 1800 by 1800, 900 by 900, 450 by 450 and 225 by 225
The attached image shows the current status of my preparations for the
renderings proper, as well as the underlying workflow by using
multicolored concentric circles for each square-degree quadrangle.
See you in Khyberspace!
