We report on an exploratory project aimed at performing immersive 3Dvisualization of astronomical data, starting with spectral-line radio datacubes from galaxies. This work is done as a collaboration between theDepartment of Physics and Astronomy and the Department of Computer Science atthe University of Manitoba. We are building our prototype using the 3D engineUnity, because of its ease of use for integration with advanced displays suchas a CAVE environment, a zSpace tabletop, or virtual reality headsets. Weaddress general issues regarding 3D visualization, such as: load and convertastronomy data, perform volume rendering on the GPU, and produce physicallymeaningful visualizations using principles of visual literacy. We discuss somechallenges to be met when designing a user interface that allows us to takeadvantage of this new way of exploring data. We hope to lay the foundations foran innovative framework useful for all astronomers who use spectral line datacubes, and encourage interested parties to join our efforts. This pilot projectaddresses the challenges presented by frontier astronomy experiments, such asthe Square Kilometre Array and its precursors.
