AW: [vtkusers] Cell Picking to return FE element ID?

[Timo Frenzel]

I don't understand your problem exactly...
But if your problem is that you pick IDs of a wrong body you should try to
turn it unpickable

actor -> PickableOff();

If you can't pick any point or cell IDs afterwards, the other body may not
contain these. Perhaps you have to convert your original to a pickable
dataset.

Try to copy it, to a polydata (with DeepCopy or CopyStructure) or
similiar... 

Good Luck, Timo Frenzel.

Betreff: [vtkusers] Cell Picking to return FE element ID?

Hi,

I read in my finite element results as unstructured data and then render
them.  I'd like to use cell picking to ID certain cells from the FE model.

Right now, cell picking returns the ID of the rendered primative (i.e., a
face of one of the elements) rather than the original element ID.

How can I return the FE element ID rather than the rendered face ID (which
is meaningless in terms of the original FE data)?

Thanks,

Steve
