We livecoded a planetarium! I didn’t get any photos of the slub performance as I was a little busy, but Matthew Yee-King’s photos are here. Thanks to Pete ‘the dome’ for all his hard work, and sorry for nearly blowing up his speakers :/ Fluxus is now compatible with Plymouth University’s Immersive Vision Theatre!

Some pics of the wronghead’s performance:

There are more on my flickr page, and some movies too…

The planetarium projection seems to work quite well now. I’ve made the angle and number of cameras it uses configurable, and I also alter the texture coordinates so the visible segment of the sphere corresponds to the entire texture (so you use all the pixels in the texture target, basically). It also uses orthographic projection for rendering the sphere:

This is another photo of my failsafe bin lid testing rig. It looks a bit more convincing than this really shows, the key thing (I think) is that the segments of the sphere appear to be the same distance apart in the bin, while being squashed in the flat version:

Slowly getting there, pollution, new animated note triggers and a cursor for making them, and tidying up the planetarium projection code so it’s easy to plug it into an existing script, and it plays nicely with all the camera operations.

Tests for extremely wide field of view planetarium projection (more on this soon) using fluxus’s new render to texture feature – thanks to Gabor for adding it.
