Having successfully completed the first of many planetarium shows, I want to start investigating writing graphics software for circular displays. Michael O'Bannon clipped a conventional rectangular laptop display to a circle, and that worked pretty well. I want to project onto polar coordinates, and write graphics software, preferably in Java, customized for that. Any pointers to references, Cartesian to polar software libraries, etc? Thanks!

No, but I like the idea very much. Smile

This would be wonderful for circular video projection, and maybe later for spherical holographic images, inside which you could fit a performer and a small audience.

Yes, I watch far too much Star Trek.

I went walking back through this forum because my students and I are in another round of planetarium music + visuals prepping. Not much new here lately.

We are currently working on two fronts. One is drawing homemade calligraphy on the dome via Android tablets and sonifying that. In development.

The other is modulating audio waveform visualizations using gesture recognition data from the instruments.

One or two public seminars in the planetarium next year along these lines. I also hope to have a 2-day regional electro-music festival in there, once I work up the courage, maybe summer 2015.

Here are some older pix in the meantime, previously linked under their event announcements, I think.

Playing a cellular automaton on the dome and sonifying that. Mosc and Bill Fox came for that one.


Using Ge Wang's sndpeek, with some code tweaks, to visualize waveforms from a zero-input mixer duet. I find waveform visualization works well with zero-input mixer.

2014!
