“…The CAVE environment has also been used for volume visualization previously. But most of the existing volume visualization tools in the CAVE only have the basic 1D histogram based TF editing, which can be difficult to manipulate in an immersive environment to achieve good results.A system of volume rendering in the CAVE was first proposed in [11]. This system had a primitive 1D TF editor, where the color and opacity values could be separately placed.…”

Volume visualization is a popular technique for analyzing 3D datasets, especially in the medical domain. An immersive visual environment provides easier navigation through the rendered dataset. However, visualization is only one part of the problem. Finding an appropriate Transfer Function (TF) for mapping color and opacity values in Direct Volume Rendering (DVR) is difﬁcult. This paper combines the beneﬁts of the CAVE Automatic Virtual Environment with a novel approach towards TF generation for DVR, where the traditional low-level color and opacity parameter manipulations are eliminated. The TF generation process is hidden behind a Spherical Self Organizing Map (SSOM). The user interacts with the visual form of the SSOM lattice on a mobile device while viewing the corresponding rendering of the volume dataset in real time in the CAVE. The SSOM lattice is obtained through high-dimensional features extracted from the volume dataset. The color and opacity values of the TF are automatically generated based on the user’s perception. Hence, the resulting TF can expose complex structures in the dataset within seconds, which the user can analyze easily and efﬁciently through complete immersion.

“…However, it did not demonstrate any capabilities to work in head-mounted displays. Another visualisation system called COVISE was able to perform volume rendering visualisation in a virtual environment that works on CAVE-like systems with various user interactions [19]. However, the issue of occlusion for dense isosurface structures from large volume data has not been addressed.…”

The visualisation of isosurfaces is an important step towards the understanding of many physical phenomena. Physical simulations produce large amounts of quantitative numerical information which need to be interpreted by domain experts. Traditionally, researchers use standard tools to create isosurface visualisations from fluid simulations and extract knowledge. With the recent evolution of display technology, it is now possible to create immersive visualisations of such data. Benefits include a higher bandwidth of communication between the data and the user, e. g., by using stereoscopic display technology and head tracking. Since the data is intrinsically 3D spatial, the use of the immersive environment supports natural visualisation, exploration, and analysis of isosurfaces. In this paper, we present the study and the design of a method and a workflow to display isosurfaces in heterogeneous immersive environments. In particular, we address the problem of scale and structure inherent to this type of data. We provide a set of tools to process large volume datasets to eventually display it in 3D immersive environments. We demonstrate the workflow of tools with a usage scenario that involves a dataset from direct numerical simulation of a wall-bounded turbulent flow.

“…Several immersive VR volume rendering solutions have been implemented over the past two decades [154][155][156][157][158], but only three remain that are still under active development. The first is VFIVE or the Vector Field Interactive Visualization Environment [159][160][161].…”
