[vtkusers] Combining datasets (sort of)

[Joey Mukherjee]

I have four independent datasets, each of which make up a line.  Say its a line 
with around 2600 points.

I wish to connect point 1 of line 1 to point 1 of line 2 to point 1 of line 3 to 
point 1 of line 4, and do this for each of the points in the line.  Basically, 
I'll be making a lot of tetrahedrons.

Is there an easy way to do this?  The only thing I could think of was to use 
AppendPolyData to make one big dataset and redo the connectivity.

Also, I am only plotting a few of the points by using vtkMaskPoints.  Ideally, I 
would like those masked points to be the ones connected.  I suppose I could take 
the output of the masks and put them into a AppendPolyData instead of using my 
original data set, but still, maybe there is an easier way.

Thanks for any ideas...

Joey
