The Mountains of Triangulum


I thought it might be fun to take an HI data cube and plot each slice as a surface, rather than a map. This is the M33 galaxy at a particular frequency where the height, rather than the more usual colour, indicates brightness.

More to come when I can get the frequencies to animate.

  1. Thanks for the share. I went for a wee (internet) paddle in the shallows, here. I was wondering about the broader context and utility of alternate data visualisation methodologies and contexts; a creative recombinatory metamorphosis of systems analysis methods, technologies, conceptual vocabularies and frameworks perhaps being my central academic interest. I found that there is some interesting work being done in this area.

  2. Yeah I've read that one, and they cite me. :) I was hoping my cheap(ish) VR headset would be fun to see what data looks like in real 3D, as opposed to just 3D-but-on-a-2D-screen (http://www.rhysy.net/frelled-1.html) but alas Blender's limits make this very difficult with the method I'm using. Might be possible in the next version though.
