Hi David,

Thanks for you using it.

Yes, you are right.
At the first, I copyed them from python's examples.
So there may be some words "python" in comment part of the ruby samples :-)

After built by make (4),
you can install them to your system by typing
"%make install",
which install vtk files to proper path under CMAKE_INSTALL_PREFIX
and ruby files to ruby_site path (default).
If you specified
VTK_RUBY_LIB_DIR, VTK_RUBY_ARCH_DIR, and VTK_RUBY_SETUP_ARGS(--prefix="/hoge"),
*.rb files are installed to /hoge/VTK_RUBY_LIB_DIR,
and *.so files are to /hoge/VTK_RUBY_ARCH_DIR.

There was bug in vtk/util/vtkImageImportFromArray.rb: "rescue" -> "rescue LoadError".
After the fix, it works without narray.
So it is not necessary to move to "vtk/narray" I think.

I skip because it was discussed in another thread.
