Re: [osg-users] Problem with readNodeFiles
Hi Paul,
Good detective work, the lack of return was the problem as the
FILE_NOT_HANDLED result was being over written by latter operations.
Added a return in fixes the problem and :
osgviewer cow.osg dumptruck.osg.(-5,-5,-5).trans
Works correctly once more :-)
Fix now checked into svn/trunk.
Robert.

Hi Paul,

Thanks for looking into this. I was curious, so I thought I'd dig a little
on a Saturday night over a beer.
It appears to be a problem in src/osgPlugins/osg/ReaderWriterOSG2.cpp. The
prepareReading method checks for the wrong extension but fails to
immediately return once that has been identified as the case...
Options* prepareReading( ReadResult result, std::string fileName, const
Options* options ) const
{
std::string ext = osgDB::getLowerCaseFileExtension( fileName );
if ( !acceptsExtension(ext) ) result = ReadResult::FILE_NOT_HANDLED;
// Should return here?
fileName = osgDB::findDataFile( fileName, options );
if ( fileName.empty() ) result = ReadResult::FILE_NOT_FOUND; //
Should return here too, right?
osg::ref_ptrOptions local_opt = options ?
static_castOptions*(options-clone(osg::CopyOp::SHALLOW_COPY)) : new
Options;
local_opt-getDatabasePathList().push_front(osgDB::getFilePath(fileName));
if ( ext==osgt ) local_opt-setOptionString(
local_opt-getOptionString() + Ascii );
etc
But I haven't dug deep enough to explain why the issue goes away when you
swap the order of the two command line arguments. Perhaps due to the chain
of responsibility pattern.

[osg-users] clip plane and shadow scene
Hi everyone, I have an issue combining clipplane and shadow scene. I first used a scene with a standard osg::group where I attach a clip node with a clip plane cutting the scene along the Y axis. Things worked well so far and I saw the scene correctly cut in half. Now if I remplace the osg::group with a osgShadow::ShadowedScene the problem starts. What happens then is that the scene will not be cut anymore, but only the shadow will be impacted by the clip plane. So I will see on the display the full scene uncutted with the shadow cut in half. What I would like to see is the correctly cut scene together with the cut shadow. I am relatively new to osg so I guess this might just be a small configuration issue, but I looked around on the web and on the mailing archive and I could not find anything on this. Thanks in advance, Vivien PS: here is the code I use to create my clip plane: osg::ref_ptrosg::ClipNode clipNode = new osg::ClipNode(); osg::ref_ptrosg::ClipPlane clipplane = new osg::ClipPlane(); clipplane-setClipPlane(0, -1, 0, 10.1); clipNode-addClipPlane(clipplane); clipNode-setStateSetModes(*_translNode-getOrCreateStateSet(),osg::StateAttribute::ON); _translNode-addChild(clipNode); and here is the code I use to create my shadow scene: osg::ref_ptrosgShadow::ShadowedScene shadowscene = new osgShadow::ShadowedScene(); shadowscene-setReceivesShadowTraversalMask(ReceivesShadowTraversalMask); shadowscene-setCastsShadowTraversalMask(CastsShadowTraversalMask); osg::ref_ptrosgShadow::StandardShadowMap shmap = new osgShadow::StandardShadowMap(); shadowscene-setShadowTechnique(shmap.get()); _translNode-addChild(shadowscene); ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Bug in osg::Texture::computeInternalFormatWithImage / osg::Image
Hi, assume you create a picture using GL_BGRA format using osg::Image::allocateImage(int s,int t,int r,GLenum format,GLenum type, int packing) or you set the format with osg::Image::setInternalTextureFormat. Both methods do not check if the internal texture format is valid. Calling osg::Texture::computeInternalFormatWithImage then results in a valid texture format because this function also does not check if the texture format is valid. I am willing to provide a patch but I would like to have an input where I should patch the source code. I prefer to do it in osg::Texture::computeInternalFormatWithImage. Next question: assume the format is wrong which format should be taken? Hartwig Thank you!

Re: [osg-users] ScreenShot File name
Hi Danny,
I'm using OSG inside of ActiveX control (based on OSGActiveX example) embedded into HTML
page. First time when I'm loading it and each time I'm taking snapshot, I'm getting
test_0.png and each snapshot overwrites this file.
When I'm pressing F5 or reloading page using IE address bar I'm starting to
save snapshots as test_1.png and each snaphot overwrite this file.
This behavior continues each time I'm reloading page. the counter is being
incremented by one to test_2, test_3 etc
the only solution for this problem is to close IE and to wait till ActiveX
unloads from Memeory. after it the counts start form zero.
Check the code for osgViewer::ScreenCaptureHandler::WriteToFile in
src/osgViewer/ScreenCaptureHandler.cpp. There must be a bug there. It's
pretty simple code, so you can make your own version of WriteToFile that
does whatever you want, and then use an instance of your class in the
constructor of ScreenCaptureHandler.
// pseudocode
class MyWriteToFile
: public osgViewer::ScreenCaptureHandler::WriteToFile
{
MyWriteToFile(filename, extension, savePolicy)
: osgViewer::ScreenCaptureHandler::WriteToFile(filename, extension,
savePolicy)
{
// ...
}
operator()(...)
{
// ...
}
// ...
};
// then...
osgViewer::ScreenCaptureHandler* _scnsvr;
_scnsvr = new osgViewer::ScreenCaptureHandler(new
MyWriteToFile(test,png,osgViewer::ScreenCaptureHandler::WriteToFile::SavePolicy::OVERWRITE));
(if you do find a bug in the existing code please let us know so we can
fix it for future versions of OSG though)
Hope this helps,
J-S

Re: [osg-users] Bug in osg::Texture::computeInternalFormatWithImage / osg::Image
Hi Hartwig, If you set a format that isn't supported by the OpenGL driver and you get an error then so be it. Fixing the code that sets up the image with a valid texture format is what should be done. Trying to catch and correct for a problem in user application set of OSG data is rather pushing what the OSG should and can be expected to do. This is particularly the case when what formats that might be supported that can be driver dependent. Robert.

Re: [osg-users] [build] How do I successfully deploy a OSG app?

Yes you do need the correctly MSVC re-distributable to be installed as part
of your applications installation process
you can also deploy all in the same folder: your exec + all the bin
folder resulted from OSG install step + the neede MSVC stuff:
you can obtain it by adding this patch to the main OSG CMakeLists.txt:
@@ -243,14 +238,6 @@
SET(CMAKE_EXE_LINKER_FLAGS_DEBUG /debug /INCREMENTAL:NO)
ENDIF(NOT OSG_MSVC_DEBUG_INCREMENTAL_LINK)

-OPTION(OSG_MSVC_INSTALL_MFC_LIBRARIES Set to ON to include
system libraries in install dir OFF)

-ENDIF(OSG_MSVC_INSTALL_MFC_LIBRARIES)
- ENDIF(EXISTS

then build osg with
cd osg_build
cmake -DCMAKE_INSTALL_PREFIX:PATH=your OSG install folder
-DOSG_MSVC_INSTALL_MFC_LIBRARIES:BOOL=ON osg source folder
cmake --build . --config Release
then you should have in your OSG install folder/bin all you need to
add to your exe to make it deployable

Luigi
You need to ensure that the MSVC re-distributable's and the OSG bin\dlls are
in your path and that your install all the OSG dlls including the plugin-in
directory etc

How do we deploy an OSG app that we compiled in VC++ 2008?
Because simply the .exe will not work on other computers (naturally).
I've tried using VC redist. and friends, but with no avail...
I have heard of static linking, but how would that work?
I would greatly appreciate any helpful response!
Thanks!

Re: [osg-users] clip plane and shadow scene
Hi Vivien, shadow rendering uses shaders and therefore replaces the fixed function pipeline (FFP). The clipplane functionality is part of the FFP and is not part of the shadow rendering. To solve this you'll need to add clipplane functionality to the shadow rendering shader. Note that this should be solved by OSG in the future once shader composition is implemented. -- Roland -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=25637#25637 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

(We want to use the osgViewer library, but the initializers caused problems for us.) I'm afraid I've only done part of the work on replacing the static initializers, the only areas that I've cleaned up the ones that I was tackling during other work. Curiously only yesterday I was starting to think about what's left to do for 3.0 and the static initializers was one of own personally todo items. Do this work as a community task might be appropriate, a different thread would be the place to do this. Even if he was able to do it, I don't know whether the changes were small enough for your purposes. But for us to take another step on 2.8.x (as stable instead of developer) would be comforting. I suspect the changes for static initializers would often be a bit too intrusive as it'll come with other changes. One could possible try and tackle the task for the 2.8 branch and 2.9.x series separately, but.. this comes with more resources needed. If you can dive in a help out then it might make it more possible. My guess is that Paul already has more than enough tasks to do to put 2.8.3 together without other tasks pilling on top. If a set of non intrusive changes can be supplied to Paul in a form that he can easily review and merge without risky stability or portability then it'll have a better chance of making it in. With the 2.9.x series the scope is still more open to more intrusive changes.
