Tutorial: Scientific Visualisation and Digital Twins: Bridging Data Models and Scene Representations using VTK, ParaView, OpenUSD, and Omniverse
What is a digital twin?
A simple everyday analogy is tracking a ride in real time: you see a live representation of a moving system, its context, and its expected behaviour, and you use that information to plan. Scientific and industrial digital twins are far more complex, but they build on a similar idea: connecting a visual representation of a system with data, models, context, interaction, and decision-making.
This tutorial explores how scientific visualisation can support digital twin workflows. We will look at how data, geometry, simulation outputs, scene context, interaction, and narrative can work together to support understanding, communication, and critical reasoning.
Across the tutorial, participants will move through short talks, guided demonstrations, hands-on activities, and discussion. The aim is to experience how visualisation adds value in digital twins: helping people explore complex data, place results in context, communicate across disciplines, and reflect on trust, provenance, interpretation, and design choices.
