  VIRUP is a new C++ open source software that provides an interactive virtual
reality environment to navigate through large scientific astrophysical datasets
obtained from both observations and simulations. It is tailored to visualize
terabytes of data, rendering at 90 frames per second in order to ensure an
optimal immersion experience. While VIRUP has initially been designed to work
with gaming virtual reality headsets, it supports different modern immersive
systems like 3D screens, 180 deg. domes or 360 deg. panorama. VIRUP is
scriptable thanks to the Python language, a feature that allows to immerse
visitors through pre-selected scenes or to pre-render sequences to create
movies. A companion video (https://www.youtube.com/watch?v=KJJXbcf8kxA) to the
last SDSS 2020 release as well as a 21 minute long documentary, The Archaeology
of Light, https://go.epfl.ch/ArchaeologyofLight have been both 100% produced
using VIRUP.
