[vtkusers] Transparency

[Banks, Robert]

Hi all.

Two questions, although the answer for one, may be the same for the other.

I have a dataset that is the cross sectional displacement of a model. However, that model is in void, so there is no displacement in the void. When I plot the info, I get a large band of color around the data relating to the 0 value of the displacement in void. Is it possible to hide or make this data transparent? Or should I window the data?

I'm thinking, I could set this color value to transparent, but am not sure how this would affect the rest of the data, having a transparent color data value in the middle of the plotting range.

The second question is on a similar vein. Using the same example, if I have a model of, say 5 different materials, which I have defined each material as a different color. Can I just set that color value to fully transparent to hide it in the rendered picture?

Or is there a better way to achieve the described problems?

Thanks
Robbie
