InsitUE - Enabling Hybrid In-situ Visualizations through Unreal Engine and Catalyst

In-situ, in-transit, and hybrid approaches have become well-established visualization methods over the last decades. Especially for large simulations, these paradigms enable visualization and additionally allow for early insights. While there has been a lot of research on combining these approaches with classical visualization software, only a few worked on combining in-situ/in-transit approaches with modern game engines. In this paper, we present and demonstrate InsitUE, a Catalyst2 compatible hybrid workflow that enables interactive real-time visualization of simulation results using Unreal Engine.
