“…One disadvantage of this approach is that full support for the display application is often limited to those platforms on which the framework itself is supported, limiting cross-platform distribution and support. One way to mitigate this is to distribute a light version of the framework along with the application; CMS Fireworks [10] takes this approach. However, issues of platform support for the light framework event display made with VP1 [4,5]; b) a CMS 3D event display made with iSpy [6]; c) an ALICE 3D event display [7]; d) an LHCb 3D event display [8]; e) a Belle II VR event display [9]; f) a CMS 3D event display made with Fireworks [10] and for the visualization application can still exist.…”

A further disadvantage to the full-framework (and even light-framework) approach is that one must also support various versions of the data format along with the underlying framework API.…”

In modern High Energy Physics (HEP) experiments visualization of experimental data has a key role in many activities and tasks across the whole data chain: from detector development to monitoring, from event generation to reconstruction of physics objects, from detector simulation to data analysis, and all the way to outreach and education. In this paper the definition, status, and evolution of data visualization for HEP experiments will be presented. Suggestions for the upgrade of data visualization tools and techniques in current experiments will be outlined, along with guidelines for future experiments. This paper expands on the summary content published in the HSF Roadmap Community White Paper [1].

The CMS experiment supports and contributes to the development of the next-generation Event Visualization Environment (EVE) of the ROOT framework with the intention of superseding Fireworks, the physics analysis oriented event display of CMS, with a new server-web client implementation. EVE-7 is a rewrite of EVE for the ROOT-7 era, using modern C++ and relying on ROOT’s built-in http server for communication with GUI clients. Part of EVE-7 is also implemented in JavaScript and uses OpenUI5, JSROOT, and Three.js as its foundation libraries. While some of the advanced features of EVE have not yet been ported to EVE-7, the existing code-base can be used for building of demonstrator applications serving as technology preview. FireworksWeb is currently at the stage of a minimal application built around EVE-7. Several advanced Fireworks features have been ported into EVE-7 in an experiment-independent manner, relying heavily on Cling, the C++ interpreter of ROOT: dynamic table views, handling of physics object collections, and filtering of objects within physics collections.

“…Fireworks is the official physics analyis oriented CMS event display since 2008. Its unique and powerful feature is its full interactivity with CMS Event Data Model (EDM) [1,2]. From the very beginning, it has been intended to assist with physics analysis, trigger performance monitoring and evaluation, reconstruction algorithm development, and to facilitate development and debugging of detector geometry description.…”

The divergence of windowing systems among modern Linux distributions and OSX is making the current mode of event display operations difficult to maintain. In order to continue to support the CMS experiment event display, Fireworks, we need to explore other options beyond the current distribution model of centrally built tarballs. C++-server web-client event display is a promising direction that can maintain the full functionality of Fireworks, including operation from the full experiment framework. In addition, it brings new features like multi-user debugging and the possibility to implement more elaborate visualization of non-event data through remote access to independent services. We have been exploring mainly in the direction of Fireworks-based C++ server and thin web-client user interface as it allows for a large degree of reuse of existing algorithms as well as for full access to CMS data formats and accompanying functions that are crucial for the correct physics interpretation of event data. This paper presents the basic architecture of the system, discusses the communication protocol between server and client, and shows existing prototypes that demonstrate the feasibility of advanced event display features. *
