Voxel Accessing Question

Hello,
The application we are writing here requires considerable modification
to the volumetric data being rendered. For example we may wish to
low-pass filter the entire volume, or flood fill a region with a given
color/intensity. In particular we need to alter A SINGLE voxel within a
brickSetCollection.
This is probably a very simple question but here it is anyway.
Assuming a multi-brick volume how do I efficiently access and modify
voxels within this volume. I would like a simple addressing system
treating the volume as either a
1D or a 3D array. Problems would include the need to cope with multiple
bricksets as generated when performing 2D interpolation and different
datatypes such as unsigned byte and unsigned short etc.
Although I can see ways of doing what is needed, I just thought Id post
the question to see the thoughts of others on this list.
Regards
Mark..
