I’m just back from the Siggraph Asia 2012. I was impressed by the people I met, the talks and courses I attended, and why not, the places I visited. Singapore is a very interesting city for a tourist. Among the people I met, a particular meeting was long overdue. I finally had a chance to meet Paul Bourke personally.

We collaborated (meaning he helped me ;)) in the fisheye implementation for the Blender Game Engine back in 2009. Since then there is not a fisheye related question that I don’t bounce by him first. So, in between talks he kindly shared his thoughts for stereoscopic rendering for domes. It took me a week to work around the problem, but here you can see the first real renders in a patched Blender with Cycles.

The formula is very simple, it’s just one of those problems that is really hard to debug (at least when you don’t have a dome with 3d projectors at hand). Thankfully in my flight back I had the peace of mind to wrap that up.

As a teaser, this is all you get for now. More on that later 😉

9 Thoughts on “3D Fulldome – Teaser

  1. Well, I now have a HD stereo capable projector (F35 AS3D) ready to be installed in the iDome. So we may be able to test it sooner than you think.

  2. Colors aside, the anaglyph version may already tell whether or not the result is satisfactory (in a conventional display it looks cool already)

    If I can gather some computer power I could try to render out an animation inside this kitchen. Need more GPU/CPUs 🙂

    Can the render engine be built on linux based supercomputer.
    If so I can offer you 10,000 cores.

  4. I guess it depends on the supercomputer architecture and whether or not I would need to build all the libraries for the system (which is a pain some times).

    Now, is this a cluster of multiple computers or one single computer with tons of cores?
    Blender doesn’t automatically handles a cluster, but there is a workaround: the animation is split in chunks and an instance of blender is launched on each node. For supercomputers I don’t know, would have to try.

  5. Wow, really interesting!

    It seems to assume that the observer is standing (or sitting according to iDome’s photos) in front of the iDome. That is, the fixed relationship between a viewer and the screen. Am I right?

  6. Wow — I just asked about this on Blendertarium and decided to check your site. Looks like you’re already on it! Go Dalai, go!

    • Hey Ron, nice to hear that.

      There are still some glitches, for I need to finish fixing a bug which I believe is in the “differential” rays calculation… but in the meanwhile if you have the specs (orientation, fov and radius) of the dome you have in mind I can prepare a sample anaglyph (or side-by-side) image for you to try the result of Bourke’s method.

  8. Checking this in continuity with Multiview for dome. With you and Paul working on it, it will be formidable!
