[Paraview] Copy sources repeatedly with Programmable Filter

[Magician]

Hi Hal,


Thanks for your reply.

What I want to do is:
1. Read or generate one source (Box, Sphere, or other PolyData)
2. Copying it repeatedly (hundreds of copies, along both x and y axes)

So far I wrote a VTK file including all sources,
but now I want to to change the numbers, sizes and pitches on ParaView.
