All the data in the whole Universe
Jun 19^th, 2008, 8:10pm

Hi,

I'm working on an artistic project that consists in collecting all the data available in the whole Universe and organizing it in a single tree. I know it's impossible to fulfill it, but that's the point.

So, I'm using Processing to display all the data in a tree and it looks like this:

http://adu.danieljacoby.com/app/ADUVis_004_Linux.zip

http://adu.danieljacoby.com/app/ADUVis_004_Windows.zip

The problem is I've get to a point where it's completely inaccesible and I'm not far close to the amount of data I would like to show. There's still plenty of wasted space on the screen I could use, but I don't know how. Any suggestions?

One important thing is that I want the whole tree to fit in the screen, so you can have an idea of where you are situated without the need of zooming-out, dragging or scrolling and, at the same time, be able to read the information your interested in and follow its path to the root.

I'll appreciate any suggestion, specially on how to display big irregular trees. Or maybe examples of similar things.

Thank you!

PD: Processing is incredible!!! This is my first post, I had to say this somewhere.

That's funny.

I'm sure the whole universe will never fit on my 1200x800 pixels screen *without* scrolling :-D but anyway, I see what you mean by *wasted* space. There's a sketch in traer physics library examples that could give you some inspiration (though using such a particle system in your case would certainly run too slowly) :

Wow, that's pretty cool. Thank you, antiplastik.

I don't need particles to move around since the data is almost static so I guess I would just have to calculate the initial position once (which would take a while) and then it would run normally. I will take a look to the code later and see if I come up with any idea.

It would probably take hours to calculate the final position for every particle (I waited 20 minutes and it didn't got any far). Any other idea? I'm stuck with this problem

To avoid wasting space you probably want to use some sort of space-filling fractal method. There's an interesting example that might set you off in the right direction over on Vimeo (by brew). (via http://www.processingblogs.org )

These also apparently take hours and hours to render. With lots of data you need patience or a supercomputer.
