Try the following:
Create a vtkStructuredGrid for your grid points and a vtkFloatArray for 
your scalars.
Use the grid's SetScalars method to add the scalars to your grid. 
([structuredgrid GetPointData] SetScalars scalars)
Create a vtkBlankStructuredGrid and then use the SetInput method. 
(blankgrid SetInput structuredgrid)
Then set the min/max blanking value.
Hope this helps!
