I have many vti time files which I load with the help of XMLImageDataReader and then I use the ImageDataGeometryFilter to get Polydata Output. My Idea was that I store the different files as Polydata like that:

polyData0= imageDataGeometryFilter-\>GetOutput()  
polyData1= imageDataGeometryFilter-\>GetOutput()  
and so on… if I directly map the Output as follows:  
mapper-\>SetInputConnection(imageDataGeometryFilter-\>GetOutputPort());  
I get an Image. But if I try to put the Polydata in the mapper like this  
mapper-\>SetInputData(polyData0);  
I get no Image.  
The reason why I want to do that is to queue the Polydata and load them into the mapper/renderer so that I do not have any big loading time.

I hope my text is somehow understandable!

Thank you in advance!
