3D Visualisation for Astronomy
Here we look at a range of 3D visualisation tools suitable for analysing large astronomical data cubes (which are typically in FITS format). WALLABY data cubes obtained from a single ASKAP pointing will be large, about 6k x 6k x 16,384 channels, i.e. 620 Giga voxels or 2.5 TByte.
