Can’t seem to get something to synth right? Curious about what lens is best? Ask your fellow Photosynthers here.
I have uploaded 20 first photos and tried to make my first synth in unlisted status, the process has begaun but it froze at the level of 7% and stayed with no changes for a long time, then I by chance pressed something and the synth window dissapeared. Why should I have waited for a long time to get my fisrt synth completed? What is the reason of this delay with no end in sight?
I'm sorry to hear that this was your first experience trying to upload a synth!
I cannot tell from what you tell me why no progress was made for a long time. If you could upload the Photosynth log file for your attempted synth, I might be able to tell you more.
If you would like to do this, you can obtain the log file by opening a 'My Computer' or 'Windows Explorer' window (not Internet Explorer) and typing the following into the address bar:
When the Photosynth temporary working folder opens, you should see a log file for your synth. Open it with Notepad to see details of what Photosynth was doing and where it might have gotten stuck. If you upload the log file to a public folder on your Skydrive account, I'd be happy to take a look.
Other than that, all I can do for you is tell you a little bit about the Photosynth creation process.
After you have placed your photos in the synther, given your synth a title, and pressed the [Synth] button, these tasks will be performed:
>> Each JPG will be converted to DZI format.
These will be stored in the temp/photosynther/images folder, so be sure that whichever hard drive the temp folder is on has enough free space to store the converted images.
>> The synther will ask the Photosynth website if an exact copy each image has ever been uploaded before. If the site already has a copy, the synther will skip the upload. If the site does not already have a copy, the synther will begin uploading the DZI version of each new image right away and continue as long as there are more images.
>> The synther will examine a 2 megapixel copy of each image for corners + blobs, make a description of a square patch of imagery around each corner|blob, and try to match them.
>> The synther will attempt to line up all of the matches found in the previous step in 3D. This is called 'Scene Reconstruction' and is the most labor intensive portion of the synthing process, but on a 20 image synth shouldn't really take long at all. (There just won't be all that much to line up.)
>> The synther will save the 3D coordinates of the feature points (the point cloud), the camera positions, and a list of which images were able to be matched to others, so that 2D view of the synth will able to be laid out appropriately.
>> After the last image is uploaded, the synth files described in the last step will be uploaded to the website.
>> After the website takes a minute to verify with the synther that all files have been correctly uploaded (Publishing phase), you should be able to view the synth immediately.
Most of all, I would just say to you, "Try it again.".
The only reason why the synth window would have disappeared is if you accidentally closed it by pressing the 'X' in the upper right corner of it.
