It's very encouraging to write to someone with problems and see them addressed and fixed so quickly. Henri, just wanted to say, “Thank You” for all of your hard work. ?

Using the thumbs version I've managed to produce a 289k point cloud instead of 168k for Kelvingrove Art Gallery, Glasgow. The big issue is the memory used, as we can't use cmvs to create cluster... @Nate Lawrence: I’ve updated both source code and binary (PhotoSynthToolKit3.zip), thanks for finding bugs !

Here are two synths that trigger that error message every time for me:

Kelvingrove Art Gallery, Glasgow

Empire State Building Aerial Synth

I’m interested in seeing how your workflow compares against the dense reconstructions viewable in the video presentations of Blaise’s. PhotoSynthTileDownloader downloads the photos just fine, but the toolkit has problems when fetching the binary files.

It'll work with a window 64-bit but not in a 32-bit vmware. But depending on your pmvs2 options you'll need a lot of ram (8gig or more). The other option is to use my BundlerMatcher + Bundler and use CMVS to cluster the job in reasonable size (take a look at the <a href="http://www.visual-experiments.com/2010/09/23/pmvs2-x64-and-videos-tutorials/" rel="nofollow">second video</a> created by josh harle). @Dave: you need to download the 64 bit version of PMVS2 (pmvs2_x64.zip) and replace it in your Photosynth Toolkit.

Would trying something with CMVS or just keep using my old 32-bit mac vmware? I was able to do a low-resolution (thumbnail) version of a photosynth I put together. It was pretty amazing and the colors were much more photorealistic than when I used SynthExport or ARC3D. Thanks for putting this together! I'm trying anything I can to get a little higher-resolution model together (hence the 64-bit attempt) so please let me know if you have any advice.

I was talking about SynthExport - sorry - didn't mention Going to try on another box.Made myself a little "notepad" file with links to the "archeology" synths ( best pointclouds apparently ) and shoot up synth on a fresh box,fresh win install. Thx for your quick reply.

Are you talking of SynthExport or PhotoSynthDownloader ? You could also provide a link to a synth that doesn't work for you... Otherwise It'll be very hard for me to help you. If you are referring to SynthExport, I'll suggest you to use the SynthExport <a href="http://synthexport.codeplex.com/discussions" rel="nofollow">discussions forum</a>. @Bernd: Could you be more precise please ?

Any tips or tricks do see how this affects requesting from the server ? Hmmm – managed to get one synth file immediately after closing Firefox
Worked once ( cloud + cameras )
Couldn’t reproduce this unfortunately…

First there were the timeouts and when I increased the timeout settings it just can't reach the server.

FYI I'm not the one you succeeded to replace the "Wireshark" method. It was first implemented in <a href="http://synthexport.codeplex.com/" rel="nofollow">SynthExport</a> (in C#), then I've implemented a C++ version and managed to convert PhotoSynth camera's parameters to Bundler format in order to use PMVS2. @Bernd: it still works fine for me.
