Summary0003826: Model slice intersections are not colored by scalars
Description

If you have a model with scalars that you are mapping through a colortable, then when that model is shown in the slice planes, the model color is used instead of the scalar color.

This leads to models in the Slice Viewers to be a different color than the model in the 3D viewer.

In my specific case, I have run a connectivity filter on the polydata of a model. This labels each object with a region id. I can render the objects in 3D and use the region id to pick a color for the model from a look up table. But when that model is sliced, the lines are drawn in the default model color, not the color resulting from running the region id through the lookup table.

Yes, I've looked into this in the past. Turns out that the vtkCutter code does not provide interpolated scalar fields (if I recall correctly it is some other scalar field to do with the intersection calculation). So there is not a simple solution for this issue.
