Re: [osg-users] Strange results from osgviewer
Hi, Robert, thank you for your suggestions. I used the svn version and there is no difference. Now, when I can add some images to my post I included a screen-shot of 'osgviewerQt', when the two 3D models are not displayed correctly, these are 'cow' and 'dumptruck', left top and right top windows respectively. [Image: http://obrazki.elektroda.pl/2590187500_1329991217_thumb.jpg ] (http://obrazki.elektroda.pl/2590187500_1329991217.png) Secondly, after building OSG last night, I have noticed that now I cannot even run the examples showing use of textures, I have problem with 'osgtexture2d.exe' - this one crashes, 'osgtexture3d.exe' is fine but it doesn't display the texture, it says only that it could not open files. What is the difference between 3d model of 'cessna' and 'cow', why only one of them is displayed ok. Thank you!

Re: [osg-users] Strange results from osgviewer
Hi Chris, What hardware are you using? Could you try another system with different hardware and drivers? Also could you try running the following in a console: osgconv cow.osgt cow_fromosgt.osg And then post the cow_fromosgt.osg, this might offer some insight in what might be going amiss. You could also try: osgconv cow.osg cow_fromosg.osgt osgviewer cow_fromosg.osgt And: osgconv cow.osg cow_fromosg.osgb osgviewer cow_fromosg.osgb If the binary (.osgb) works and the text (.osgt) version doesn't it would suggest something wrong with the parsing of the text file. In the past we have seen problems with some ascii file loaders with handling different local settings - i.e ten point 1 being 10.1 vs 1,10. The only possibility I can think of is that you have an out of date OpenSceneGraph-Data. Robert.

Re: [osg-users] Strange results from osgviewer
Hi, I tried to convert cow.osg and cow.osgt to .osgt, .osg, and .osgb all possible combinations. Using osgviewer, the results are the same. The 3D model is loaded only with few vertices, exactly the same as on the screen-shot above. In terms of the hardware - I'm using a laptop, not too old, and the only problem is the Intel's integrated graphics card. To be honest I had a problem with video streaming in Qt when I used openGL to display video frames, it was incredibly slow. Anyway, I think I will stop here as I need to move on with my work. Textures work fine in few cases, I can load some simple objects, therefore it should be enough. I am not planning to do anything huge at the moment so the current setup should be enough. I have different problem but I will post that as a new post as it is not related to this one. Thank you for your time.

Re: [osg-users] Strange results from osgviewer
Hi Chris, Intel drivers are well known for causing problems and suspect this may be causing the problems you are seeing. The Intel drivers under Linux do appear to be a little more stable than Windows so if you can dual boot your system it might be worth experimenting with. Also look to see if there are any updated drivers for your laptop. Robert.

Re: [osg-users] Strange results from osgviewer
Hi, The version of OSG I'm currently using is 3.0.1. I tried both source code and binaries, the same problems in both cases. Apart from the issue with displaying some of the 3D models I have noticed that I cannot see any textures I use them in my program. Even the examples provided with OSG do not display any textures. Is it required to have dependencies like 'libpng' and 'libz' etc. present in the system before building OSG? Because this is the only thing I missed when I was setting up OSG on my computer. Thank you!

I tried both source code and binaries, the same problems in both cases. Could you try svn/trunk. There have been a few updates to the serializers/.osgt/.osgb/.osgx support since 3.0.1 so there is chance the problem is now resolved, although as I can't spot a specific bug fix for the type of problem your are seeing this is a bit of long shot. One thing of note is that I don't recall other Windows users using 3.0.1 reporting problems as you've described so there is chance there is something specific about your setup. Trying out svn/trunk is worth trying out either ways as if it does turn out there is bug lurking a fix to this will be made against svn/trunk before it gets rolled out to stable releases. Apart from the issue with displaying some of the 3D models I have noticed that I cannot see any textures I use them in my program. Even the examples provided with OSG do not display any textures. This is likely simply an issue of now having the image plugins that these models require to handle images in them. Is it required to have dependencies like 'libpng' and 'libz' etc. present in the system before building OSG? This are optional dependencies - you don't need them to build the OSG, but if you have models that use formats such as png you'll need the associated dependencies. You can use the published 3rd party dependencies to get the most commonly used external dependencies.

Re: [osg-users] Strange results from osgviewer
Hi Chris, Which version of the OSG are you using? Robert. On 28 January 2012 19:29, Chris Blizniak bliznia...@hotmail.com wrote: Hi, I've got a strange problem. By running osgviewer.exe dumptruck.osgt. The 3D model is not displayed properly. The problem exists with the following models: cow, dumptruck, cessnafire... I haven't tested more. There are no problems with displaying cessna.osg or robot.osg. I cannot post a screenshot yet, as I need to have at least two posts. The result from osgviewer is quite strange and it looks like only certain number of vertices has been loaded. It simply doesn't display a whole mesh but only few lines. Thank you!
