Opacity mapping for surfaces doesn't work in Slice representation
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Steps to reproduce:
- run paraview(builtin server)
- Add Wavelet
- Add Calculator, expression "RTData - 100"
- Color by variable Result
- Open the Color Map Editor. Check the "Enable opacity mapping for surfaces" option.
- switch the representation to Surface. The opacity function should cull away some of the surface.
- switch the representation to Slice. The opacity function does not work.
There appears to be something special about data ranges that are negative at the minimum and positive at the maximum. Note that when the data range is entirely positive, opacity mapping seems to work fine.
