As recommended in this forum, I installed both osg and vpb from svn
and I was able to reproduce the example with the Punget terrain.
Now I want to try it with planets, starting with the moon.
I started trying with these parameters --geocentric --spherical
--radius-equator 1735000 but I get this error:
ERROR 1: Unable to compute a transformation between pixel/line
and georeferenced coordinates for moon_heigth.tif.
There is no affine transformation and no GCPs.
I assume I could add that transformation in a world file or creating a
geotiff file, but I am not sure how to do that.
I also assume that the bluemarble options only works at Earth scale,
as in this example:
Sorry if these are faqs, I am a newvbie and there is not much
documentation about this subject.
I will appreciate any advice.
