[vtkusers] Input of Volume Rendering

[Xianjin Yang]

Hi vtkusers,

It seems to me that vtkVolumeMapper accepts file inputs of vtkImageData only. I
do not have any vtk or slc files. Instead, my data is a structured grid out of
finite difference modeling and it is stored as float arrays in the memory. Is
there any way for me to pass my data into vtkVolumeMapper? Is there any filter
or utility in VTK to transform my data into vtkImageData?

Thank you for your help.

Yang
