[vtkusers] Creating a simple mesh of lines

[Jochen]

Hi,

don't create for every node a single actor. This slows down the rendering
process  in case you have 10000+ nodes or the like. 
Use Glyph3D instead.

Having one actor in total is enough to render an unstructured grid. Nodes
should be represented as glyphs having spheres as the source.
 Please refer to the  http://www.vtk.org/Wiki/VTK/Examples/Cxx c++ samples
in VTK-WIKI  or to  http://www.vtk.org/Wiki/VTK/Examples/Python python
samples in VTK-WIKI  to learn more about displaying unstructured grids and
using glyphs respectively glyph3d.

In case you need more assistance on that you're welcome to come back to me,
being aware my response time won't be the fastest due to the fact I'm
working very hard in the moment. Sorry for that.


with best regards

Jochen
