[osg-users] troubles with osgTerrain::NoDataValue

Hi Ilia,

I recently add support for reading and writing osgTerrain::NoDataValue in .ive plugin, but I didn't have the time to add it in .osg.
What is going amiss, is that it is not implemented at all :) but it should be quite staight forward to do it

Be also aware that even if gdal and osgTerrain can handle noda values, VirtualPlanetBuilder is unable to do so (probably because it relies on osg::HeighField in a first step of computation)
