[Paraview] Integrate globe view into custom application

[Shawn Waldon]

Hi Tobias,

I'll let others answer your first few questions since they have more
experience there.  But I can answer your question about updating based on
camera position.

To do this you'll want to use the mutliresolution streaming support.  There
are some details here:
http://www.paraview.org/ParaView/index.php/Multi-Resolution_Rendering_with_Overlapping_AMR
The best example code is probably in the Streaming Particles plugin.  This
can be found in the ParaView source tree under Plugins/StreamingParticles.
There should be an example data source that produces streamable data as
well as the ParaView representation to support streaming.  You'll probably
have to customize your own versions of both since these were designed to
work with sets of points rather than geometry.
