that picture above is the kind of thing that I am looking for.

I use Windows OS.

I will check again to see if there is any way that Google Earth can do this. They could easily make the software show this kind of display - if that's what they choose to do.

My own problem is that I need this software to work for Central America and South America. So I will check the sources that have already been mentioned. It seems like someone must have a 3D Earth mapping tool ... it must exist.

My own application is that I am looking at the mountains (and large hills) and matching them up with the ecosystems (biology). For example, which mountains are dry? Which mountains have rainforest? etc.
