I'm fascinated by the idea of rendering HI data cubes as landscapes. But they're not real landscapes; how you interpret them depends on how visualise them. Hence, here's M33 in my first attempt at a Matrix-style rendering. Each frame of the animation shows a single frequency channel where both the offset and value of the text indicate the flux at that position (the Matrix font for some reason renders a minus sign as something like a 7, and the formatting doesn't round negative numbers correctly, hence there are lots of apparent values of 70). It needs some more frames interpolated to slow it down but this is just a first test.
It's a Japanese "Fu" character. Dunno why they have it mapped to the minus sign. https://en.wikipedia.org/wiki/Fu_(kana)
ReplyDeleteThere's a lot to like about this particular approach. A slider bar denominated in Hz would allow the viewer to render any one frame for study.
ReplyDeleteThe art of science. That is fantastic. I am also interested to see what else you come up with and where this visualisation method goes.
ReplyDeleteEvent Horizon Thanks ! It's certainly a lot of fun to play with... I would like to explore how very different the same data sets appear using different visualisation techniques : text, graphs, surfaces, volumetrics, etc. It would be interesting to watch the same data set fade between the different rendering methods.
