Viewing Gigapans on panoramic Liquid Galaxy systems

Hi, I’m not a pano maker, just a keen viewer!

I’m sure you are aware there is a Gigapan Photo layer in Google Earth. The Google Liquid Galaxy (LG) systems basically run multiple Google Earth instances with the view synchronised to create a wide panoramic display surface. Generally 14-16 megapixels, depending on the number and type of screens used.

Up till now LG has NOT been able to sync pano images across the displays. Which is a terrible shame because Liquid Galaxy should be a fantastic technology for showing off gigapan imagery.

This week I found a glitch in the pana/ge renderer switching that can be exploited to load up the hi-res imagery and then navigate around, thru, into the image in a free-form natural fashion… up to the full resolution of the gigapan!

Pretty cool, right?

What I’m hoping from this community is help to pressure the Google Earth devs to get this style of pano loading & navigation as an option for Google Earth & Liquid Galaxy.

PS. a Liquid Galaxy is quite easy to build, you just need a bunch of PC’s, screens and some networking. See http://code.google.com/p/liquid-galaxy/

Andrew, that is great news. I was just trying to dream up the easiest way to browse gigapans in a huge display, and the liquid galaxy systems are awesome.

You guys have one in Sydney? I’ll be moving to ANU this summer and we’ll be setting up timelapse gigapixel cameras around canberra when we have the time and budget (sample of the output: http://www.gigapan.org). Since the player is flash based it embeds in google earth so maybe we could view that in an lg system as well? Would be nice to have a place to display the output so its good to know the LG system is an option.

Great post, thanks for the info.

Hi Tim,
Gigapans onto high-res flat display-walls is pretty straight forward. Either multi-head video or a multi-machine cluster and/or position-aware apps. Curved tile walls become tricky if you want to zoom in and move around within the pano.
I’m not sure how you embed flash inside Google Earth or vice-versa. Google Maps yes, Google Earth not sure.

We’re in Sydney. I’m hoping to do something with high-res pano’s captured in the field for a forest-based climate experiment (http://www.uws.edu.au/hie/facilities/face). Primarily for outreach displaying onto a Liquid Galaxy in a visitors centre, but I’m sure the scientists will get some value. We’ll also be 3d modelling the site and pulling near-real-time data into the Google Earth platform. We should probably talk!
