[vtkusers] Need help with Vectors

[Eric E. Monson]

Hello,

I think what you want is to use vtkGlyph3D, which will let you supply  
the vtkArrowSource as the SourceConnection, and then your point data  
with vector attributes (create vectors out of end position - start  
position) as InputConnection. Then each point can be "glyphed" with an  
arrow which is oriented (and possibly scaled) by the vector at each  
point.

There are some Examples that use vtkGlyph3D in the VTK source. A  
simple one which uses a ConeSource instead of an Arrow is in Testing/ 
Cxx/Mace.cxx

Good luck,
-Eric
