[vtkusers] Making custom data for a regular 3d voxel grid

[Daniel Minsky]

Dear all,

I am very new to VTK, I could follow the C++ examples to read an image 
from disk, however I would like to generate the image inside my program 
with some voxel data coming from other object in my code.

I would like to generate a vtkImageData with a regular 3d voxel grid 
values. I do have all the unsigned_char 100x200x40 voxels in a unsigned 
char array. All voxels are cubic with 1cm side.

How do I feed the vtkImageData object with my data array?

How do I use the vtkImageData? The vtkImageData does not have the 
GetOutputPort() method to feed a Mapper and I am very confused about the 
correct pipeline.

My final goal is to make a 3d image of the data within an upper and 
lower thresholds and an arbitrary plane slice.

Kind regards,

Daniel
