Over the years, CRS4 has developed a wide variety of methods capable of rendering potentially unlimited volumetric models on modern GPU platforms. These visual computing methods have found application in different fields, from medicine to science and engineering.
After introducing in 2008 the first adaptive method capable of interactively displaying static volumes of potentially unlimited dimensions, the work continued by introducing various state-of-the-art compression methods (2012) and techniques for the visualization of time-variant data (2019-2020).
In particular, the following work introduced the first single-pass technique working on out-of-core data on a GPU:

The following two works were the first to introduce advanced codecs based on tensor decomposition and sparse coding:
