[vtkusers] recovering the Polydata

[Giancarlo Amati]

Actually I saved the list of my actor in a vector. And well the input is deleted once I has set the actor in the renderer. If I would saved the input, where there would be no mean of using getmapper()->getInput(). 

I checked the actor, and I verified the input and everything seems ok.
:(

I am just wondering , maybe I am wrong, but if you delete the Input then Actor->GetMapper()->GetInput() should fail . Maybe that is your error here ?

Actor.Getmapper()->GetInput() work well for me.

Verify your input

Hello everybody,

I am trying to retrieve the polydata linked to a particular actor. I have my actor saved in a list
I used the "GetMapper" function to get the pointer to a vtkMapper * and the I used


the function "IsA" to test if it is a vtkPolyDataMapper.
The IsA function returns true and I used

vtkPolyData *pd = mapper->GetInput();

to retrieve the polydata, but somehow I don't get anything reasonable and the number of vertices is 0.



is that the right way to retrieve a polydata from the pipeline?

Many thanks.
Giancarlo
