Hi Felipe, Have you seen: http://www.kitware.com/blog/home/post/722? This blog post shows you how to setup a live connection and describe a simple pipeline using python. The pipeline was generated from Tools/Manage Plugins, Catalyst Script Generator Plugin, Load Selected. Then you can build your pipeline and export it using CoProcessing, Export State. We don't have an example with only C++. Setting up the visualization pipeline as well as the connection to catalyst live, while possible, is more involved in C++. Basically, you'll have write in C++ some of the code in simple.py and coprocessing.py. In your specific case, maybe you are missing the calls to coprocessor.DoLiveVisualization(datadescription, "localhost", 22222) or coprocessor.EnableLiveVisualization(True, 1) These are lines from the python coprocessing script that you'll have to rewrite in C++.
