[osg-users] wrong lighting with scaled stl
Hello, when I load a STL-file and I scale this geometry up, it is black and when I scale down it is white. It seems that is a problem with the lighting. Any ideas, what is my mistake?

Re: [osg-users] wrong lighting with scaled stl
Hi, your normals are being scaled with the geom. You can put something in the stateset to rescale normals. I think, but check it up, GL_NORMALISE will do, but you can also use GL_RESCALE_NORMALS if you are using same scaling for all axes. If you can't find osg code for this, ping the list again. jp Martin Großer wrote: Hello, when I load a STL-file and I scale this geometry up, it is black and when I scale down it is white.

Re: [osg-users] osgMovie and the ImageStream Object
Hi Bruce, The movies plugins (ffmpeg/quicktime/xine) create ImageStream objects on the heap for reading the movies and start their own threads. They pass this ImageStream back via a ReadResult where a ref_ptr holds it, then the calling code takes charge of this either via the ReadResult or via the raw C pointer as in the case of the convenience function readImageFile(), with the later the ImageStream is taken form the ref_ptr in the ReadResult in a way that resets the ref counting to 0 without deleting it. When using the readImageFile its the callers responsibility to properly manage it either by keeping a local ref_ptr for it, or passing it on to the scene graph. As for nasty situation... we'll worse that will happen will be a memory leak if you are a sloppy programmer. Personally I make assumptions that people who use the OSG are grown up enough to handle a pointer correctly and not have to nanny them with every little thing that they can do with the OSG. Robert. On Mon, Mar 8, 2010 at 2:44 AM, Bruce Wheaton br...@spearmorgan.com wrote: I had a bit of trouble tracking down where the ImageStream object is handled, and I think I've worked it out, but it's quite odd, even for a demo. As far as I can tell, an Image is created from the provided file name and held in a pointer. That image is cast to an imagestream for some housework. A texture is created and the image is set as it's source - this is all a pointer, as far as I can tell, not the refPtr I expected to see. Then, the main thread seems to forget about the image/s, and moves on. It then goes into a visitor, which finds any images and makes a ref pointer list to them. Is that about right? So there's a ref pointer and a raw pointer floating around at once? And for a while, only a pointer? Isn't that a pretty nasty situation? Am I missing some C++ kung-fu to make refPtrs in the texture or earlier? Is there an example with a 'better' management of image/stream objects?

[osg-users] RedHat versions and ffmpeg version
Hi All, CDash is reporting errors with some changes I made to ffmpeg to fix the deprecated warnings: http://cdash.openscenegraph.org/viewBuildError.php?buildid=1557 The build error boils down to the RHEL 5.4's avcodec.h not containing the new ffmpeg method, but still having a version number modern enough to fool the guard I added to ensure backwards compatibility. The problem is I've just spent half an hour trying to divine exact which version ffmpeg introduced the new methods, but there changelogs and svn logs just don't tell me enough, and online searches haven't given me any further of clue. So RHEL users which version of ffmpeg do you have on your system. If you could post the avcodec.h this would be ideal as then I'll be able to look at the LIBAVCODEC_VERSION_* values directly and hopefully be able to work out an effective guard for our code.

Re: [osg-users] Could not find plugin on Mac OS X 10.6.2
Hi Tobias, I do not know at all OSG, the Cmake build is structured to search at configure time (cmake-gui or ccmake or cmake-Dpreset variable) the needed plugin dependencies and include plugin code if the dependencies is found. The search code for dependencies are either in CMakeModules/Findxxx.cmake or in the cmake root/Modules folder It seem to me that the user is not currently able to configure at config time which plugin to build. Probably the easiest thing in your case would be to edit the CMakeModules/FindQuickTime.cmake to make it fail in your situation (adding an exception for OSX and 64 bit) This patch has probably some chances to be accepted. Otherwise, a more general solution, would be to insert some form of user CMake configurability. One of the simplest think would be to allow to override the CMAKE_MODULE_PATH. So you do exactly the same change to FindQuickTime.cmake but not need to change the svn copy, just put it in your module override folder and configure with cmake -DCMAKE_MODULE_PATH:PATH=your override module folder I have tested module overriding in windows and Linux and it seem to work. in order to activate module override, a simple patch to master CMakeLists.txt is needed If I am not alone in asking for module override, I' ll send a submission request HTH Luigi Tobias Duckworth wrote Hello again, Thanks for your prompt response.

I look forward to hearing from 'the OSX guys', and hope that in the future I can provide similar support to others.

Re: [osg-users] Shadows and negative renderbin?
Hi all, I just wanted to mention for the sake of closing this thread, that the problem was caused by the shadows and the skydome both having a texgen state on the same texture unit. This caused two things I could observe: 1. No shadows at all when the skydome's renderbin was set to a negative number (I still don't understand that one) 2. When the skydome was in a positive-numbered renderbin, shadows were visible on some objects but not on others (so shadow application was wrong, which helped Wojtek to suggest a problem with possibly conflicting texgens. Apparently, it's been noted a long time ago that when two texgens are on the same texture unit, no matter the hierarchy, they will conflict (you might get the result of one when you expect to get the result of the other on your node). In my case, the texgen for the shadows is applied when traversing a node close to the top of the scene graph (the ShadowedScene), and the skydome is lower in the graph, but should never have shadows applied to it, so there is no conceptual conflict - they could share the same texture unit, if the lowest texgen (i.e. the last one traversed) took precedence. This is not the case. I could see a problem if some node needed a texgen PLUS shadows (i.e. two effects that both require a texgen), then obviously you need both and they can't share the same texture unit. But that's not my case. Is there any way to fix this so that the lowest texgen takes precedence? I realize TexGen is positional state, but there must be a way...

A quick grep reveals points me at VirtualPlanetBuilder/src/vpb/System.cpp:
str = getenv(VPB_MAXIMUM_NUM_OPEN_DATASETS);
if (str)
{
_maxNumDatasets = atoi(str);
}
So try setting the env var VPB_MAXIMUM_NUM_OPEN_DATASETS to a value
underneath your OS's limits on number of open files. The default value is
set thus:
_maxNumDatasets = (unsigned int)(double(vpb::getdtablesize()) * 0.8);
So it does attempt to look at what your OS is set up to handle, perhaps the
0.8 ratio is overly optimistic, or perhaps part of the VPB setup isn't using
the _maxNumDatasets correctly.
Robert.

Re: [osg-users] Trying to place a shape in 100 random positions?
Trajce (Nick) Nikolov my_Trans[i] = new PositionAttitudeTransform; Thanks so much, that did the trick. Can now successfully put 100 spheres into the scene in random positions, Thanks a lot! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=25371#25371 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
