Hi,

I have a set of DEM files and should implement a multi-resolution terrain rendering \
solution. And ultimately place some 3D data objects to terrain view.

Because my data visualization already utilizes VTK, I'm looking for a solution that \
would use VTK also for terrain rendering. I took a look to vtkGeoView and \
vtkGeoTerrain classes, which already implement a multiresolution scheme. I just \
couldn't figure out how to get from DEM files to correct data representation. 

- How to process DEM files to get proper vtkGeoSource geometry tiles?  
- Do I manage with elevation data and color map only, or do I need some texture file \
                to cover earth surface? 
- It is possible to use vtkGeoView and vtkGeoTerrain to render terrain for smaller \
                areas than the whole globe? 
- And I'd like to render in planar projection, not spheric, as GeoView currently. \
Possible?

Some question to start with. I'm a bit confused...

Thanks,

Olli
