This demo video gets its own post because the effort gone into this project has been frankly outlandish.
#datavisualisation
I finally resume updating my website. This new section collects a lot of different data visualisation projects in one convenient location. Come explore the gas in the Milky Way, the Virgo cluster, and the entire nearby Universe... and then take a walk along the Arecibo telescope in virtual reality and see the sky at radio wavelengths across the world.
Probably needs a good check for typos but that can wait.
Training session I gave last Friday on viewing 3D FITS files in #Blender. I must have really caught most of the bugs by now since nothing went wrong during the live demos...
Preparing a data visualisation training program and having some fun with the demonstration files. This is an ALMA PHANGS map of the CO clouds of the galaxy NGC 2903. Basically clumps of the densest molecular gas where star formation happens, shown as a volume render and with contours at 5 sigma (4 sigma gives a more interesting result, but that creates a 12 million vertex file which is a right bugger to work with).
More website updates. A smaller one this time, looking at how we turn radio #astronomy data into visually meaningful images.
I stole some of my increasingly depleted time to make this little animation of the hydrogen contours of M33. Well, isosurfaces to be more accurate. The third dimensions is velocity, not distance. I've done these before, but now I extended it to show the surfaces at different flux levels, which is quite fun.
