I'm newbie, so I've some questions.
But first of all, I want say thanks to OSG developers - it's really cool
I've GIS-system, which can return altitude for given coordinates, I need
to create a 3D scene according these altitudes. I don't need
textures - it's enought to paint terrain according to altitude (high
altitude - brown, low altitude - green). I'm going to use PagedLOD
for this. What is the best way to build such LODs?
I've found only one way - first create an "digital elevation map" file
and then process it with osgdem from VirtualPlanetBuilder. Is it
possible not to use such intermediate file?
May be there is exists a another correct way to reach such goal?
And second question - as I noticed, osgdem working much faster, then
output format is height field database. Is it possible to assign
different colors to different heights in osg::HeightField?
