[vtkusers] Individual color and opacity for each voxel

Hello!

I need to display volume according to image processing results passed from
another classes. Result is 3D array where each element is representing
desired voxel opacity and color. Volume size and dimensionality is equal to
3D array ones. Task is to display original volume according to values found
in array.  I've read manual and looked inside source cde and found that only
piecewise or gradient color/opacity mapping is possible, or some ways to use
scalar values lookup table for original volume. But this is not what is
needed exactly.

How to implement such individual voxel opacity/color using VTK?  If this is
impossible, what is the best way to implement this?

Best regards,
Maksim.
