ParaView [1] is a high performance visualization application not widely used in HEP. It is a long standing open source project led by Kitware[2] and involves several DOE and DOD laboratories and has been adopted by many DOE supercomputing centers and other sites. ParaView is unique in speed and efficiency by using state-of-the-art techniques developed by the academic visualization community which are not found in applications written by the HEP community. In-situ visualization of events, where event details are visualized during processing/analysis, is a common task for experiment software frameworks. Kitware supplies Catalyst[3], a library that enables scientific software to serve visualization objects to client ParaView viewers yielding a real-time event display. Connecting ParaView to, for example, the Fermilab art framework, will be described and the capabilities it brings discussed. We will further discuss introducing a visualization "protocol" and generalizing this capability to other visualization systems.
