The Visualisation Activity Area gathers experts, developers, users and all people from the Particle Physics community interested in interactive data visualisation and event displays.

The group started activities in October 2016 and it is convened by Riccardo Maria Bianchi (University of Pittsburgh, US, ATLAS Experiment).

All are welcome to join the group and participate!

Goal

The goal of the group is to discover common approaches, foster collaboration among HEP experiments and groups, plan future software development and developing common tools.

Description of the group

Here follows the description of the group, its challenges and the questions which it should address, as defined by the group itself during the Visualisation session in the HSF Workshop in San Diego (see link in the meetings' list below).

The first task of the group was the writing of a common white paper about Visualisation issues and challenges in HEP, and possible solutions, in a time scale of 5-10 years. The paper is now completed and published on arXiV: https://arxiv.org/abs/1811.10309.

Scope of the group activities

Visual representation of event data overlaid with detector geometry for the purpose of HEP research, education and outreach. This representation can be static (event displays) or time-dependent (animations).

Out of scope

  • Visualisation of detector infrastructure and systems (eg. slow control)
  • Visualisation for statistical data analysis (histograms, etc…)

Group Challenges

  • Find common approaches, promoting common tools
  • Improve support for the following use cases:
    • detector design (geometry browser)
    • simulation and reconstruction development
    • physics analysis
    • outreach & education
  • Improve support for required platforms and devices
  • Ensure sustainability for key software packages
  • Improve low latency access to data, low entrance cost, from a sisualisation point of view
  • Improve rendering performance

Some open question to shape the group activities

  • Can we develop a common framework such that experiments can plug in geometry and event data in their own formats/data?
  • Can the data delivery be web-based?
  • Can we develop a collaborative (“multi-player”) tool to visualize and interact with event data and geometry in real time and a distributed manner (Google doc for sisualisation)? How will this capability advance HEP research and outreach?
  • Can we have common graphics engine?
  • Can we think about common visualisation tools with other fields (astrophysics, geophysics, etc…)? And can we learn something from them?

Interaction with other groups

Topics for which we will have to interact with other groups:

  • Data access (data handling, frameworks)
  • Geometry description (simulation group)
