If you know the behavior will be OBE by Opticks 4.4.0, please let me know. 2010-06-29T07:35:33 with either dynamic generation turned on or off, you should only see "black" or "view background" squares if we run out of video texture RAM 2010-06-29T07:36:51 so you might try and confirm that using something like GLView: http://www.realtech-vr.com/glview/ 2010-06-29T07:36:56 to determine how much texture memory you have 2010-06-29T07:52:26 what is a "view background" square? 2010-06-29T07:52:38 I usually saw all white squares, occasionally i saw black squares. 2010-06-29T07:54:05 the background color for the view 2010-06-29T07:54:08 which defaults to black 2010-06-29T07:54:17 Fairly certain black was the background color for the view. 2010-06-29T07:54:22 why would i see white squares instead? 2010-06-29T07:54:47 provided white isn't the background color, i'm assuming the histogram stretch is determining every pixel inside that square region should be colorized as white based upon the raw values 2010-06-29T07:55:56 so I would zoom in and verify the pixel values 2010-06-29T07:56:30 when i zoom in, it fixes itself, and goes back to displaying data like normal 2010-06-29T07:56:37 interesting 2010-06-29T07:56:48 OPTICKS-558 addressed a similar issue where the background color would sometimes be displayed, but that was fixed in 4.3.2 2010-06-29T07:56:50 that usually indicates a problem with the texture generation, because we generate new textures as you move across zoom boundaries 2010-06-29T07:57:58 for a given box of pixels, on a given frame, it usually is not all white. occasionally for that frame, for that box of pixels, it is all white. 2010-06-29T07:58:31 do you have any large datasets (ie: 4k x 4k x 50 frames) available. 2010-06-29T07:58:38 i have yet to reproduce this problem with data you can access. 2010-06-29T07:58:45 you can use CubeCreator to create an image of that size 2010-06-29T07:58:48 could you try that? 2010-06-29T07:58:55 where is CubeCreator? 2010-06-29T08:00:16 https://opticks.ballforge.net/files/documents/8/36/CubeCreator.zip 2010-06-29T08:00:30 another thing about reproducing 2010-06-29T08:00:30 run on the command-line and it'll print all it's arguments 2010-06-29T08:00:47 all machines reproduced on, were 64 bit machines 2010-06-29T08:00:55 if you can create a cube creator image that causes the problem 2010-06-29T08:01:01 let us know and then I'll try and reproduce on my machine 2010-06-29T08:02:11 will do. thanks. 2010-06-29T08:02:12 . 2010-06-29T08:02:12 . 2010-06-29T08:38:56 New news from opticksannounce: Opticks Programming Contest - Winner Announced || Opticks Programming Contest now closed || Only 3 Weeks Left to Win Opticks Programming Contest || Updated roadmap for Opticks releases || Scheduled website maintenance || Spectral Processing Extension 1.0.0rc1 Released || Opticks 4.3.3rc1 Released || Python Scripting Extension 1.0.0rc1 Released || IDL Scripting Extension 1.0.2rc1 Released 2010-06-29T09:10:20 New news from opticksannounce: Opticks Programming Contest - Winner Announced || Opticks Programming Contest now closed || Only 3 Weeks Left to Win Opticks Programming Contest || Updated roadmap for Opticks releases || Scheduled website maintenance || Spectral Processing Extension 1.0.0rc1 Released || Opticks 4.3.3rc1 Released || Python Scripting Extension 1.0.0rc1 Released || IDL Scripting Extension 1.0.2rc1 Released || Win a PS3 or Wii in the Opticks Programming Contest! || Spectral Processing Extension 1.0.0 Released || Python Scripting Extension 1.0.0 Released || Opticks 4.3.3 Released || IDL Scripting Extension 1.0.2 Released || Spectral Processing Extension 1.0.0rc1 Released || Python Scripting Extension 1.0.0rc1 Released || IDL Scripting Extension 1.0.2rc1 Released || Opticks 4.3.3rc1 Released || New Production Extras Release - Extras 1.0.1 || New Production Release - Opticks 4.3.2 || New Release - Opticks 4.3.2rc2 - second release candidate for 4.3.2 || Opticks Programming Contest - Help Get the Word Out || New Extras Release - Extras 1.0.1rc1 - first release candidate for 1.0.1 || New Release - Opticks 4.3.2rc1 - first release candidate for 4.3.2 || Win a Wii in the Opticks Programming Contest! || Video Tour - 4.3.1 New Features || New Production Release - Opticks 4.3.1 || New Release - Opticks 4.3.1rc2 - second release candidate for 4.3.1 || New Release - Opticks 4.3.1rc1 - first release candidate for 4.3.1 || New Release - Opticks 4.3.1Unofficial for Linux - first alpha release for Linux || New Production Extras Release - Extras 1.0.0 || New Production Release - Opticks 4.3.0 || New Extras Release - Extras 1.0.0rc1 - first release candidate for 1.0.0 || Announcing Opticks Extras || New Release - Opticks 4.3.0rc1 - first release candidate for 4.3.0 || New Production Release - Opticks 4.2.5 || New Release - Opticks 4.2.5rc1 - first release candidate for 4.2.5 || New Production Release - Opticks 4.2.4 || New Release - Opticks 4.2.4rc1 - first release candidate for 4.2.4 2010-06-29T09:15:31 *** rforehan has joined #opticks 2010-06-29T09:31:16 . 2010-06-29T09:31:25 i was able to reproduce on a network most Opticks core developers can access. 2010-06-29T09:31:33 i am going to create an even bigger dataset, to see if the problem is more noticeable. 2010-06-29T09:34:12 BTW, there should be a warning that anyone with epilepsy should avoid cubecreator 2010-06-29T09:34:25 ;) 2010-06-29T10:19:31 *** gmartin_cn has joined #opticks 2010-06-29T11:24:07 . 2010-06-29T11:24:07 . 2010-06-29T11:24:17 Not sure if the larger dataset is that much worse. It certainly is no better. I can reliably reproduce. 2010-06-29T11:24:40 Not knowing much about how Opticks displays raster elements, i'll say the following. 2010-06-29T11:25:58 I notice the Status Bar says Generating Image each time i step a frame in directionA. 2010-06-29T11:26:12 I stop and step in directionB, and Status Bar does not say Generating Image until a number of frames have been stepped through. 2010-06-29T11:26:18 I assume some sort of caching is going on. 2010-06-29T11:26:31 It seems like the problem doesn't appear when initially generating images. 2010-06-29T11:26:39 Seems like it happens 1-5 frames after playing through some "cached" images. 2010-06-29T11:28:28 yes, it has a I believe 100 MB texture cache 2010-06-29T11:28:34 so i step/play through a number of frames which do not cause the 'Generating Images' message to be output to Status Bar, then afterward hit some frames which do cause the Generating Images message to be displayed. Seems like within the first 1-5 frames which cause Generating Images to be displayed, i see the problem. 2010-06-29T11:28:39 and I also believe it is LRU, so as you animate through a large image it will start purging entries once it's full 2010-06-29T11:28:45 and only when it can't find it in the cache will you get that status bar message 2010-06-29T11:28:51 I verified that my spatial data view's background color is black. 2010-06-29T11:29:00 can you send me an e-mail with location of the sample data? 2010-06-29T11:29:02 I verified i almost always see white blocks (the one or two times i saw black blocks may have been immediately after an import). 2010-06-29T11:30:29 I verifiied i can reliabily reproduce this with Enable Dynamic Generation unchecked. 2010-06-29T11:30:35 I have yet to see this behavior with Enable Dynamic Generation checked. 2010-06-29T11:30:55 Also noted my problem is reproducable by adjusting brightness contrast sliders. 2010-06-29T11:31:00 will send email to kstreith 2010-06-29T11:34:48 email sent 2010-06-29T11:35:43 zooming, clicking the spatial data view, or clicking toolbar buttons (ie: Flip Vertically) all corrected the problem. 2010-06-29T12:26:09 *** dsulgrov has quit IRC 2010-06-29T13:52:13 *** goffena has quit IRC 2010-06-29T13:58:32 *** kstreith has quit IRC 2010-06-29T15:55:52 *** rforehan has left #opticks 2010-06-29T20:02:52 New news from nightlybuilds: Opticks4.4Dev-Nightly-Linux #30 (SUCCESS) 2010-06-29T21:07:03 *** gmartin_cn has quit IRC 2010-06-29T23:40:16 New news from nightlybuilds: Opticks4.4Dev-Nightly-Solaris #29 (SUCCESS)
