[vtkusers] how to reconstruct realistic earth surface?

[6dgis at 163.com]

Hi,All
	Now I am trying to reconstruct realistic earth surface from points.
Each point contains latitude, longitude and height. I want to reconstruct 
the realistic earth surface taking height info into account.Any idea? 
Thx in advance!

ps:Suppose the earth is a sphere.
