[vtkusers] How can I transform a vtkRectilinearGrid to a vtkImageData

[Kevin Lin]

Greetings, everyone.

Currently I've got a vtkRectilinearGrid with scalars to represent
temperature data of a room,

And now I wish to use Volume Rendering to show the data, But it seems I can
only use ImageData or StructuredPoints to Volume Render,

Can I use some filters to transform the vtkRectilinearGrid to vtkImageData?

Many Thanks in advance:)
