Topic: Forum Search Box

It would be nice to have a forum search box, to help finding threads dealing with a specific subject. Specifically, I am trying to find a thread that I have read before, and I know it is there, but I cannot find it, forcing me to open a new thread for the same issue. Such a search box is included in almost every forum.

=) Yep.

This was mentioned almost immediately after the forums first launched here on photosynth.net : 
http://photosynth.net/discussion.aspx?cat=01b6f15f-42eb-49cb-a221-ed56615e1c47&dis=3a609d46-3b0b-40fd-bbba-6c02d4769b2b

and seconded some time later here:

:: Although it would certainly be welcome built-in functionality, you can get reasonably good results from the forum using plain web search like Bing or Google.

(Begin reading at "As to searching the Photosynth forums...". In fact, you can use [Ctrl]+[F] and type "as to search" (without the quotation marks) to snap directly to the appropriate beginning point.)

Be sure to try the example Bing and Google links and swap out the "Direct 3D" and "megapixel" queries for whatever you're actually looking for. Remembering one or two of the people who took part in the discussion can also help narrow your search results very quickly to what you're looking for and that is also touched on in the post that I just linked to.

Thank you for the constructive help. I never thought of the possibility of searching a forum this way.

However, it did not help me in this case. I was looking for a thread dealing with a difference in quality between Photosynth viewer and HDView. I think I remember someone complaining that the visual quality in Photosynth viewer is less than that in HDView. I have a feeling that there is a difference, although I am not 100% sure. I tried comparing the two at high magnification without concluding results, but my general impression is that HDView looks better.

I tried using site:http://photosynth.net/ +Forum +("Photosynth" AND "HDview") in Google, but I did not find what I was looking for. Maybe my memory fails me.

Hmmm. I'm not sure which thread that is either.

Honestly, I wouldn't expect a quality difference in the photo tiles themselves. I suppose we could ask the teams if they are using the same JPEG compression quality in both the synther and ICE. My expectation is that ICE handles the generation of the Seadragon|Deep Zoom tiles for panoramas, rather than handing that task off to the synther.

I have opened up the DZIs that our JPEGs are converted to during synthing before (just copy one out of the %temp%\photosynther\images folder sometime and rename the copy's extension to ZIP) and in addition to the tiled resolutions there, there is also a low quality version of each photo found (if I remember correctly) in the Deep Zoom Collection which is created at the end of the synthing process (after Scene Reconstruction - you'll have to either be quick, have a large upload, or disconnect your internet connection to catch the DZC) called 'thumb'.

This 'thumb' version of each photo is roughly Facebook quality and is something of an oddity as it stands outside the regular Seadragon tiling scheme.

My instinct is that this 'Thumb' version of the photo is as low quality as possible to load in *something* for people to look at right away, but then the viewer starts rendering the normal tile pyramid for the photo as quickly as possible. 

It is my suspicion that this practise was begun with the Silverlight versions of the Photosynth viewers and is something of a workaround to technical limitations of Silverlight or performance of the Photosynth servers. This would explain the curious effect, especially noticable on slower connections of a newly navigated-to photo first coming in fairly clearly, then dissolving into blurriness, then resolving in the normal Seadragon fashion until all the tiles for the current size have been downloaded.
