[vtkusers] Variable alpha in lookup table based on scalar

Hi All,

I would like to use a scalar property to pilot the alpha channel of a lookup table.
The property must be different from the one that drives the color.

Suppose I have a data source (could be ImageData or StructuredGrid)

-    Cell scalars "value" --> determine RGB values

-    Cell scalars "reliability" --> determine alpha values.

I don't want to do volume rendering, just to fade out some cells in a surface representation.

What approach would you suggest?
