[vtkusers] How to change the actor data without deleting it.

[John Platt]

Hi Ahmad,

If you want to destroy a mapper, try

	Actor->SetMapper( NULL );
	Mapper->Delete();

If you use vtkDataSetMapper, you should not need to do this as this will
handle both vtkPolyData & vtkUnstructuredGrid.

HTH

John.

Hi,

I want to change the actor data (e.g. add/remove a
filer to/from actor) without removing the previous
actor and create a new one.
I have disconnected the actor from renderer before
setting the mapper but it dosen't work. The
application halts when I want to connect data to actor
using "setMapper()" method.

Do you have idea how to figure it out?

Thanks,
ahmad.
