[vtkusers] Modifying the vtkDataSet Object

[Naveen]

Hi,

I am having some trouble modifying vtkDataSet object and would like to know
how to proceed with the task. I have an object of vtkDataset having 97665
POINT_DATA values (2D) and the dimensions as (384, 256). Now we want to
convert this into 3D, so i have to add an additional Z coordinate to it. In
order to do that, I want to add atleast 1 more layer on Z axis i.e add
384*256 more POINT_DATA values to the existing vtkDataSet object. How can I
do this modification?

Thank you,
Naveen
