Re: [osg-users] setNumMultiSamples on render to FBO
Hi Bram, Deferred Shading or rendering to MRT doesn't support standard multi-sampling, as the MSAA is only used in the frame buffer resolve. There are however multiple options. 1. Make all RenderTargets multisampled and use sampler2DMS and texelFetch( sampler, texcoord, sample ) in your shaders. 2. Use super-sampling, i.e. your render target is bigger than your actual display resolution (2048x2048 vs. 1024x1024) 3. Use postprocessing anti-aliasing. Deferred shading gives you an advantage here, as you usually have the normal and depth information ready to use it for sophisticated edge detection. 4. Rely on built in post-processing anti-aliasing such as FXAA on nvidia cards. When choosing 1) there are some serious drawbacks. You will have to make most targets from your gbuffer pass multisampled and thus having a much higher load on the fragment shaders and bandwith. There are some techniques to multi-sample only fragments that are on an edge, but still there will be a lot of work. Use you preferred internet search to find some papers and other docs about multi-sampling and deferred shading/lighting. Option 2) will also be fairly limited, as it will produce really good antialiasing only if you have like 4 times oversampling (so 1920x1080 would be 8192x8192, which is a guaranteed killer on most GPUs) I personally use a mix of 2) and 3) for projects where quality doesn't have to be excellent Option 1) is the best, but is slow if done naively. cheers Sebastian P.S. Search the mail archive, there are some question of mine regarding the multi sampled buffer setup. When I switched from 'normal' rendering to deferred rendering (or how you call it) I noticed a difference in how it looked, while it should look the same. I believe now that it looks different because I use setNumMultiSamples Code: osg::DisplaySettings::instance()-setNumMultiSamples( 4 ); But in the render to multiple-textures it does not seem to do this. Is it even possible to do this? I write colors, normals and world coodinates to 3 different buffers, so I wouldn't really know if it's possible to do multi sampling on that (does it also multi sample the normals etc. then?) Anyone who can tell me more about this?

This will be an issue related to order of clean up, which is the opposite problem that I suspect with the problem that Abhishek is seeing. In your case it might be application side issue rather than core OSG - for instances could it be that your viewer is being kept in memory after the completion of main() so disrupting the normal and safe destruction order? In both cases getting small example code and set conditions that illustrate the problem are key to properly characterizing and fixing the problem.

This time it gave me segfault 2 times out of total 5. How often does it crash vs not crash? Again in debug mode with IDE and source code it crashed three times out of five. It got terminated other two times. When it terminates by itself is that after running correctly, or is does it hot bring any windows up and just exists?

[osg-users] OpenGL 3.x support
Hello folks, What is the current status of the OpenGL 3.x, 4.x support in OSG? I'm asking, because I'm quite unsure if it makes sense to move to the newer Implementations. In detail I'd be interested in the following issues: 1. Handling of Matrices etc. I know of the osg_* uniforms for the modelview/projection matrices. Is there something missing, or are the replacements there completely? (a list would be nice) 2. Handling of glMaterial etc. Is there some handling of materials, lights etc? My naive expectation would be, that there are replacements for the glMaterial and glLight calls, which are setting uniform structs. 3. Handling of various osgXXX libraries. What about basic support for osgParticle, osgShadow etc.? Is there something usable right now? Or would we have to invest further work here aswell? 4. Are there any other cave-eats I forgot? cheers Sebastian ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Save rendered frames to video file.
Hi David, a practical solution is to write frames using https://code.google.com/p/osgworks/source/browse/trunk/src/osgwTools/ScreenCapture.cpp then to convert resulting frames to video using ffmpeg or one of free video editors. you might also use ffmpeg for real time encoding frames using approaches something like in https://github.com/neilmendoza/ofxMovieExporter/blob/master/src/ofxMovieExporter.cpp http://qgismapper.googlecode.com/svn-history/r59/trunk/mapper/video-capture/CompressThread.cpp http://vpman.googlecode.com/svn-history/r7/VPM/vc-video.cpp http://dvj.googlecode.com/svn-history/r580/trunk/src/LGL.module/LGL.cpp ( there are a lot of samples just search google in cpp files for av_write_frame ) I would recommend to setup FFmpeg video codec ( lossless codec FFV1) and later convert video to any desired format using ffmpeg ( ffv1 reduces hard drive access compared with raw images - but does not load cpu much ).

Re: [osg-users] osgWindows Example Crashing on Linux
Hi Abhishek,
Thanks for the extra details. Being able to reliable reproduce the
problem is good news in that at least you should be able to confirm a
fix on your system. On my on Kubuntu system I'm not yet able to
reproduce the same error, but on repeatidly running osgwindows 100
times I was able to get the following error on one of the runs:
Warning Referenced::signalObserversAndDelete(,,) doing delete with
_refCount=4294967295
Warning: deleting still referenced object 0x236c230 of type
'PN3osg10ReferencedE'
the final reference count was 4294967295, memory corruption possible.
This looks likely to be a threading issue on destruction rather than
construction like you are seeing, it could be connected but more
likely to be something else. The way I test osgwindow was to run in
using the follow bash alias (put into .basrc)
# implement repeat command
repeat() {
n=$1
shift
while [ $(( n -= 1 )) -ge 0 ]
do
$@
done
}
Open a new bash shell to force the definitation of repeat then then in
this console tell osgViewer::Viewer::run() to only complete 10 frames
and then exit via:
export OSG_RUN_FRAME_COUNT=10
Then run the test:
repeat 100 osgwindows cow.osg
For me it can correctly for each of the 100 runs, and only once
reported the error to the console.

I will do some longer tests here to see if I can get it to reveal the

I've stripped down my OSG app to the attached archive. Upon exit there's
some threading error, not real crash. But when I make my mCamera

The Kubuntu 13.04 distribution have version 4.7.3 of the gnu compilers:
$ c++ --version
c++ (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3

I guess there is a chance that there is a relationship between the
problem you've seen a the gnu compiler version. Could you try
building the OSG on another dev system with a more up to date
compiler?
I will do some longer tests here to see if I can get it to reveal the
problems you are seeing.
Robert.

[osg-users] Culling w/ RTT
Hello everyone! I'm running into a problem in my application where I'm trying to switch between two different subgraphs as the result of some event (key press or similar). The first of these two objects is a standard subgraph with nothing too sophisticated going on. The second of these is a RTT stack of Camera objects. The problem manifests in that if I switch FROM the standard graph (just a random grouping of models) to the RTT Camera stack, the bounds of the previous node are used for the RTT Camera. This means that while the same scene rendered within my RTT stack is fine as long as you don't adjust the view matrix, as soon as you move the scene around it begins to get culled. I can remedy this problem by disabling culling on the main viewer camera when my RTT stack is in effect, but I feel like I'm doing something wrong... the reason I think this is because I can add the RTT stack to my scene as the FIRST scene (and never toggle it to anything else) and the culling occurs correctly. The problem only manifests when I switch from the RTT stack to a standard node AND THE BACK to the RTT scene. Has anyone tried anything like this in the past? Does anyone have any hints? :) ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Recommendation Graphic Card
Hi guys, can you help me find an appropriate graphic card? My OSG app is a CAD-data viewing application. Large models (full vehicles) with plenty culling. Up to 1 individual parts, for the triangle count I'd roughly estimate 20 million. Upper price limit is around 800 $. Some of my main questions: What are the benefits of professional cards (quadro and firegl) over standard cards (geforce, radeon)? (Especially for OSG applications, of course.) Which of these two professional cards would you consider more appropiate for my use case? ATI FirePro W7000 or Nvidia Quadro K4000 Or would a gaming card like Geforce 780 GTX or a 6 GB card like this one http://www.newegg.com/Product/Product.aspx?Item=N82E16814202005 be better?

Re: [osg-users] VPB build error
Hi Sebastian, I found the post and submitted a fix. It just need a minor tweak to include quotation marks to fix the semicolon that appeared in the linker options. Thanks. Martin From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Sebastian Messerschmidt Sent: 27 May 2013 09:33 To: OpenSceneGraph Users Subject: Re: [osg-users] VPB build error Hi Martin, please search the forum and the mailing list. This is a bug in Visual Studio. To get VPB linked (and possibly other tools) add /FORCE:Multiple to your linker options. @all: Should this go to the FAQ/HowTo section on the website? @Robert: This seems to be an error in VS linker. I think there was proposed patch (something about implementing the destructor IIRC). It would be nice if we could provide a workaround, as it affects basically every VS2010/12 application linking with osg based libraries. Hi All, I am receiving a build error with VPB under VS2012 using Windows 8(32bit build of OSG).
