[vtkusers] How to set multiple outputports?

[Franke, Stephan]

Hi,


I have a question to the function SetNumberOfOutputPorts. I have a source reader object that reads geometries from a file.
In this file there can be definied more than one geometries. For each geometry I need a separate visualisation pipeline. At the moment the reader source object has only one outputport so that all geometries from the file where visualize throught this pipeline. In this prozess I have no chance to give individual attribute to a geometry inside this pipline. The attribute is shared to all geometries inside the pipeline. Therefore I need for each geometry a separate pipeline and this means my source reader object needs more than one outputport. When I set fix the number for the outputports inside the constructor of the source reader object class all works fine. But the problem is that I have to know how many geometries are definied in the file and have to implement in the source code the needed number of outputports. What I want is to install the number of outputports through run time. How can I do this ? The problem is that I can not give the New() function a parameter like NumberOfOutputPorts and I do not now where I can install the number of needed ports in my source reader object class, so that the count of outputports is working during run time.
Can you  help me out? Thanks.
