example panoramas

I just created a page showing a comparison between panoramas out of Photoshop and Photosphere:

I also put one of my nicer HDR panoramas on there, but only at half resolution.

Excellent.

Do you plan to publish the algorithm?

Hey Greg,

Wow, this is impressive. Is it possible to assemble spherical panoramas based on shots captured with the Sigma 8mm?

Regarding Martin's question, I will present a poster in Boston at the Symposium on Applied Perception in Graphics and Visualization <http://www.apgv.org/>. This symposium happens right before Siggraph and is collocated, so it's a fun thing to do if you're planning to attend Siggraph anyway, or live in Boston. I don't know if or when I'll get around to publishing a proper paper on it. I'm past the CIC deadline this year, and I'm not up on the image processing literature so I feel a bit embarrassed about submitting it to the GVIP journal or someplace like that.

As for Jack's question on fisheye panoramas, I don't think Photosphere will work all that well in general. Mark Banas posted something just yesterday where he had managed to "undistort" a couple of fisheye images and provide them as input to Photosphere and it worked reasonably well.

My preference when using fisheye inputs for image-based lighting and the like is to perform the coordinate mappings and corrections directly in Radiance, and handle it as part of the rendering process. I posted an example of this in January to the HDRI list under the grab-bag subject "Mac-Mini | Photosphere | VNC".

Very cool. i leave for London tomorrow and I am bringing my camera and tripod - anyone have any suggestions/requests for good locations?

I am not very familiar with the city (i have been there once, when i was 14) but I will have about 1 1/2 days for non-business related stuff. I'm bringing a Powerbook too, so i'll get to try out the stitching in the hotel to perfect my technique!

thanks greg!

The cupola at St. Paul's is an awesome spot to shoot from. Leave the tripod in the hotel though; you won't want to haul to up all the steps, and you won't have room up there to set it up anyway.

Cool! Have fun, London's a fantastic city. I haven't been there in three years, but hope to go back in September for the annual Radiance Geekfest.

I have a little (full height but collapses to less than 12 inches tall, 3 inches in diameter) tripod, so we'll see. That looks like a great place to take in the city - nice!
