Hi Robert,

Builds and osgviewer runs fine with VS 2015 Win64.
I got these debug output to the console :

_forceVertexArrayObject = 0
_forceVertexBufferObject = 0
_forceVertexArrayObject = 0
_forceVertexBufferObject = 0
_forceVertexArrayObject = 0
_forceVertexBufferObject = 0
ViewerBase::configureAffinity() numProcessors=8
  databasePagers = 1

Cheers,
Mourad

You're right we need both :

COLLADA_BOOST_BUILDNAME : to follow boost naming convention with 3 digits
for MSVC toolset version
COLLADA_BUILDNAME : to follow collada naming convention with 1/2 digits for
MSVC toolset version

You are missing the ending 0s.
By the way the MSVCXX vars are discouraged (there is no var defined
starting from Visual 2017), MSVC_VERSION is the recommended way now :
https://cmake.org/cmake/help/v3.8/variable/MSVC14.html?highlight=msvc14

IF(APPLE)
SET(COLLADA_BUILDNAME "mac")
ELSEIF(MINGW)
SET(COLLADA_BUILDNAME "mingw")
ELSEIF(MSVC_VERSION EQUAL 1900 OR MSVC_VERSION EQUAL 1910 )
SET(COLLADA_BUILDNAME "vc140")
ELSEIF(MSVC_VERSION EQUAL 1800)
SET(COLLADA_BUILDNAME "vc120")
ELSEIF(MSVC_VERSION EQUAL 1700)
SET(COLLADA_BUILDNAME "vc110")
ELSEIF(MSVC_VERSION EQUAL 1600)
SET(COLLADA_BUILDNAME "vc100")

Hi Robert,

I think it is more correct to use the same logic (testing against the
compiler version CMAKE_CXX_COMPILER_VERSION  ) as in the mainstream
FindBoost.cmake :
https://github.com/Kitware/CMake/blob/master/Modules/FindBoost.cmake#L432-L453


Cheers,
Mourad

Re: [osg-users] Call for testing, preparing for 3.5.6 dev release again :-)

[Mourad Boufarguine]

Hi Robert,

CMAKE_VS_PLATFORM_TOOLSET is not set unless the user explicitely specifies
a toolset when invoking cmake :

cmake -G "Visual Studio XX" -T v1YY srcDir

If the user does not specify a toolset, the default toolset of the chosen
Visual Studio version will be used, but the CMAKE_VS_PLATFORM_TOOLSET
variable will not be set, and this is what is causing the problem here.

Cheers,
Mourad

But you are compiling your program in 32bit. So, either download the

OSG has some plugins to read movies. You'll need to build osg with at least
one of them. I'd suggest the ffmpeg plugin.
Then you can have a look at osgmovie example.

Basically, a movie is read into an osg::ImageStream object which inherits
from osg::Image. So you can use to texture an object as a regular image.

osg::ref_ptrosg::Image movie =
osgDB::readImageFile(your_movie.avi.ffmpeg);
osg::ImageStream* is = dynamic_castosg::ImageStream*(movie.get());
if (is) is-play(); // this will trigger the video

 Thank you Mourad and Jorge.

 ** **

 I have never used CygWin and I am trying to follow those instructions:

 ** **


 http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/Cygwin


Those are for building OSG with cygwin to be used on a PC.


 

 ** **

 But it is a bit messy for me. Mourad, it seems like you have successfully
 compiled OSG for Android in Windows. Could you please give me a quick guide
 or some tips?

 **



1/ install Cygwin ^^ , make sure to install gcc , g++, make, ... (a full
install may be helpful).

Please note that, although we won't be compiling osg with cygwin's g++ , it
needs to be installed in order for cmake to get over compiler checks at the
beginning of configuration. (and other packages may be also needed)

2/ in cmake gui, set the sources and binairies folders, hit configure and
choose Unix Makefiles as generator

3/ Check OSG_BUILD_PLATFORM_ANDROID and hit configure

4/ Set (if not set) ANDROID_NDK path

5/ Configure your build whether you want GLES1 or GLES2 following these
instructions :
http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES

6/ Configure and Generate

7/ open Cygwin batch, cd to binaires dir, and make

 needs to be installed in order for cmake to get over compiler checks at the
 beginning of configuration. (and other packages may be also needed)

 2/ in cmake gui, set the sources and binairies folders, hit configure and
 choose Unix Makefiles as generator

 3/ Check OSG_BUILD_PLATFORM_ANDROID and hit configure

 4/ Set (if not set) ANDROID_NDK path

 5/ Configure your build whether you want GLES1 or GLES2 following these
 instructions :
 http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES

 6/ Configure and Generate

 7/ open Cygwin batch, cd to binaires dir, and make

After re trying and checking, i found out that it is preferable to use the
command line cmake in cygwin rather than cmake gui :


cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF
-DOSG_GL_MATRICES_AVAILABLE=ON -DOSG_GL_VERTEX_FUNCS_AVAILABLE=ON

-DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF -DOSG_GL1_AVAILABLE=OFF

 Hi Mourad and all,

 I've succesfully built osg_3.0.1 on Windows with Cygwin (without 3rd party
 plugins for now).

 I'm now trying to build the osgAndroidExampleGLES1, and everything
 compiles, but the linker (ld) throws an error says that it cannot find the
 dds lib, here it is:

 $ ../../../../../Android/android-ndk-r6/ndk-build

 I'm checking the options of the Android.mk file and it looks like there's a
 variable LIBDIR to specify the library path which is then used here:

 [...]
 LOCAL_LDFLAGS   := -L $(LIBDIR) \
 -losgdb_dds \
 [...]

 I've already tried to set it to relative and absolute paths, I've also
 tried to copy the compiled libraries in the local example folder,
 but cannot get it finding the libraries!
 Have you got any other suggestion?



What did you put in OSG_ANDROID_DIR ?
I just tried with my binaries folder path and it worked.

Hi Hector,

 Thank you for the response. I am having some problems with the MINGW/MSYS

You have to use Cygwin not MinGW/MSYS on windows to develop with android

Hi Hector,

You can't use Visual Studio to build OSG for android. You need to choose
Unix Makefile as generator in CMake gui.

 Hi, Folks,

It's been a while since I updated my OSG files. Today I checked out the
 latest SVN release and tried to use CMake to configure for Visual Studio
 2010 64-bit build. I downloaded the 64-bit FFMPEG packages (from July 4th
 2011) and filled in all the relevant fields in the OSG CMake settings. I did
 not see any error message regarding FFMPEG when I generated the solution and
 project files. However, afterwards I noticed that the ffmpeg plugin project
 was missing. The project file was not generated at all and of course not
 included in the OSG solution file. Could there be anything that I did wrong?
 Or was it related to the recent issues with FFMPEG?

Thanks!

Yefei


Hi Yafei,

Make sure CMake did actually find FFMpeg headers and libs. I don't think it
does in windows, so you'll have to set them manually.
If CMake doesn't find FFMpeg headers or libs, the ffmpeg plugin won't be
added to the generated VS solution.

This usually mean that you are mixing code linked with shared C runtime
(osg) with code linked to static C runtime. I think you should rebuild dcmtk
libs with shared runtime (/MD msvc flag instead of /MT)



 Code:
 error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0'
 doesn't match value '2' in ReaderWriterDICOM.obj



And this means that you are mixing release and debug code. To build debug
dicom plugin, you need to use the debug dcmtk libraries.

It seems like a static/dynamic c++ runtime conflict. Check if osg and

/MTd flag or both with /MDd flag)

charm (only a tiny problem with osgViewer, when cross compiling for android
using cygwin, the windows path in osgViewer/CMakeLists.txt is used rather
than the android one, fix attached).
For the moment I only compiled all the osg libs and plugins that don't rely
on a 3rdParty lib. I will let you know when I succeed to build an app for my

Re: [osg-users] How to do a videostreaming

[Mourad Boufarguine]

Hi Nagore,

You can get prebuilt ffpmeg libs for Windows here
http://ffmpeg.arrozcru.org/autobuilds/.

Your question is not clear : do you want to read and render video streams in
osg or do you want to stream osg rendered frames over network ?

The first can be done using ffmpeg or directshow plugins (look at osgmovie
example or at osgviewer --movie).
The last is not implemented in osg, and you have to code it yourself using
for example ffmpeg libs and/or Live555 libs.

  Hi,

 First, thank you for yours help!

 I have some problems to compile FFmpeg in Windows. I'm going to try with
 directshow.

 Do you know any example of stream with dshow in OSG?



 Thanks in advance!

Re: [osg-users] How to do a videostreaming

[Mourad Boufarguine]

 My case is the second one. I want to stream osg rendered frames over
 network.

 So, I have to install ffmpeg libs. But, Must I install Live555? Or if I use
 ffmpeg it will be enought? What is your recomendation?


Hi,

Ok, it is more clear now.
Well, it should be possible to use only ffmpeg, but I think it is difficult
with Windows :)
FFmpeg distrib contains a streaming server application (ffserver). I didn't
hear of someone who succedded to build and make ffserver work on a Windows
machine. I didn't also find a Windows port of this program.

Anyways, the big steps to stream rendered frames, is to encode them (using
ffmpeg) and then stream them (ussing ffserver or Live555).
Encoding the frames is not difficult to do. At least you should be able to
save the rendered frames in a video file following the output-example.c
sample shipped with ffmpeg sources (
http://ffmpeg.org/doxygen/trunk/output-example_8c-source.html). At the osg
part, you can do reder-to-texture to get the raw rendered frames.

The streaming part is more challenging. If you manage to make ffserver work,
it would be straightforward. all you need to do would be to write the output
of the encoded frames into a ffserver feed (like in this
http://www.mygeekproject.com/?tag=ffserver)
Otherwise, you can use live555 for streaming. The problem with that is there
is no concrete documentation on ffmpeg/live555 integration, but, it is
feasable. The main difficulty is to choose a working combination of a ffmpeg
encoder and a live555 streaming container and to configure them accordingly.

Re: [osg-users] [build] OSGbin 2.9.9 v. 2.9.11

[Mourad Boufarguine]

Hi Neil,

I can't see what is your problem ? OSG contains the core libraries and
nodekits ( Openthreads, osg, osgDB, osgGA, osgFX, osgViewer, etc...) wich
will give the versioned dlls in bin folder (osg71-osg.dll -- osg library ;
osg71-osgGA.dll -- osgGA library ; etc ...) and plugins for loading/writing
files. These plugins are in a osgPlugins-2.9.11 folder, and are like this
osgdb_xx.dll. osgdb_osg.dll is the plugin for loading osg files and is
different from the osg71-osg.dll.
 which is the osg library.

  That's working!!! Finally!  :D
 I installed the ffmpeg plugin and loaded the movie with .mov.ffmpeg

 problem.
 Only the audio is not playing... but that's no much important.

 Thanks again!


Hi Almir,

Glad it helped.
I think you can't get audio from ffmpeg plugin out of the box (although it
already contains an audio decoder). I think you need to implement an
osg::AudioSink to produce the sound. I found this thread that talks about an
implementation of AudioSink (using SDL) used with the ffmpeg plugin :

You can open the osg file with a text editor and check the texture unit. Can

Hi Chris,

Well, we have a running WPF based application that includes an osg viewer.
Here is how we did that : (i am no WPF coder, so i can't be very specific
about it) :

- in the WPF side, we created a subclass of System.Windows.Window.
In Window_Loaded method, we get a handle of the window like this :
IntPtr winPtr = new WindowInteropHelper(this).Handle;
this handle will be used to initialize the osg viewer.

- We created a simple wrapper dll with a simple C interface that manages an
osg viewer.
our C interface has create/destroy/frame/loadmodel methods.

- this wrapper dll is loaded in the WPF application with a DllImport
statement per method in the C interface.

- back to the wpf side, in Window_Loaded method, we pass the handle of the
window to the create function in the wrapper dll. This function creates an
osg graphic context as you already have and create an osgViewer object using
that context.

- Still in the wpf side, we have a Paint method in which we call the frame
method of the wrapper dll that simply call the frame method of the viewer.
Make sure to add this to the ctor of the window :

CompositionTarget.Rendering += Paint;

I hope this will help you.

Re: [osg-users] How to build OSG using Eclipse CDT on Linux *in debug mode*?

 Hi,

 I used cmake-gui to generate Eclipse CDT4 makefiles. No problem then
 building OSG and running the osggeometry sample.

 However, whenever I try to debug a sample (I place a breakpoint in main(),
 then click Debug) Eclipse says No source code is available for main().
 Apparently, this might be because I am not compiling OSG in debug mode.
 Some people say this error might happen if you don't specify -g -O0 in the
 compiler options.

 Again the sample runs just fine, and I can see gdb is correctly doing its
 work in the Eclipse tool windows.

 My question is the following:

 When I right-click the OpenSceneGraph@binaries node and select
 Properties, I see no Build configurations, typically Release and Debug. I
 guess Build Configurations are reserved for native Eclipse CDT projects, not
 makefile projects.
 So - where shall I specify compiler options in Eclipse CDT for makefiles
 projects, in order for the build to be a debug build?

 Thank you!

Hi Heiko,

These two methods were added two weeks ago to BufferData in svn/trunk. The
only reason I can think of, is that you didn't build release osg libs
recently, or you are linking to an old osg.lib. Check your linker paths.
Maybe a clean build can help you.

Re: [osg-users] How to set camera focal length

[Mourad Boufarguine]

Hi Igor,


 But i still can't set up the position and rotation of the viewer's camera.


 this-_viewer.getCamera()-setReferenceFrame(::osg::Transform::ABSOLUTE_RF);
 this-_viewer.getCamera()-setViewMatrix(::osg::Matrix::translate(0.5, 0.3,
 0.1));

 this does nothing.

 My guess is becase i also have to call:

 ::osg::ref_ptr ::osgGA::KeySwitchMatrixManipulator keyswitchManipulator =
 new ::osgGA::KeySwitchMatrixManipulator;

 keyswitchManipulator-addMatrixManipulator( '1', Trackball, new
 ::osgGA::TrackballManipulator() );

 this-_viewer.setCameraManipulator( keyswitchManipulator.get() );

 or the offscreen capture doesn't render the scene, just an empty
 background. It looks like viewer needs a camera manipulator or it won't
 render the scene.


 Is it at all possible to move the camera programmatically after a camera
 manipulator has been set for the viewer? Or can i avoid creating a camera
 manipulator?


Well, it seems like the cameramanipulator is causing this. To define
manually a view matrix for the camera viewer, you need eigther not to use a
camera manipulator or to set the second parameter of
Viewer::setCameraManipulator (resetPosition)  to false.

Be aware that in case you don't define a camera manipulator, calling
Viewer::run() will automatically add a TrackballManipulator. In this case,
just replace the Vewer::run() call by the rendering loop :

while(!viewer.done())
{
viewer.frame();
}

Another possible issue is the view matrix itself. If you don't see the
scene, it is generally due to a wrong view Matrix.

 how can I fix this?



This is rather a Qt issue.
You need to move the OsgViewerQt class declaration to a header file, and
moc it.

These links should help you :

http://doc.trolltech.com/4.7/moc.html

To make your life easier with VS and Qt, you may want to install
QtVSAddin (http://developer.qt.nokia.com/wiki/QtVSAddin)

Hi Cosimo,


 Meanwhile, are there other possibilities to implement OSG 2.8.2 with Qt?


Yes, take a look at osgviewerQT example.

Re: [osg-users] Disable the Mouse default event in osg

[Mourad Boufarguine]

Hi Lalit,

If i comment the manipulator then data is not displaying.


When you don't use a camera manipulator, you should take care of the the
view matrix of the viewer.
You can use something like

viewer.getCamera()-setViewMatrixAsLookAt(eye, center, up);

For more information about this function, google gluLookAt.

Hi Gerry,

It seems like you need to adjust your view matrix in order to see the new
scene. If you have a camera manipulator, it can do it for you by calling
home(). Hitting the space bar should do the same thing.

Re: [osg-users] Human 3d model animation/motion

[Mourad Boufarguine]

Hi Sanat,

A quick answer to the 3rd point :

On Wed, Jul 7, 2010 at 2:04 PM, Sanat Talmaki sanat.sch...@gmail.comwrote:

 Hi,

 I am trying to create a scene in which I want to add 3d models of humans
 and control their motion through keyboard and/or automated.

 However I am having trouble starting off as I'm not sure what exactly to
 do. This is what I've done so far:

 1) I looked at the DOF node and tutorial and figured that I would need a
 human model with DOF nodes at the hands and legs linkages. I looked at
 http://www.makehuman.org/ but was not sure if this was the way to go to
 obtain 3d human models with DOF nodes in them.

 2) So far the models of other vehiclces I'm using in my scene are composed
 of a number of .lwo files that I link using PAT nodes and can move each part
 individually. But I believe that with models having DOF nodes, I would get a
 single file but with those nodes specified in them. Is my understanding
 correct ?

 3) I tried to convert a .flt model to .osg from the tutorials dataset using
 osgconv but got this message:

 C:\tools\OpenSceneGraph-2.8.2_Release\binosgconv.exe
  C:\Users\Sanat\Desktop\CE

 Warning: Could not find plugin to read objects from file

The spaces in your paths are causing the problem. try this :

osgconv.exe  C:\Users\Sanat\Desktop\CE
M_Res_Software\OSG
Code\NPS_Tutorials_src\NPS_Data\Models\t72-tank\t72-tank_des.
flt C:\Users\Sanat\Desktop\CEM_Res_Software\OSG

Models\t72-tank\tank.osg


 So I was hoping to get some pointers as to how I can proceed ? (I have my
 3d scene ready but just finding it hard to figure out how to get a human
 model to move)

 Thanks

 Sanat

Re: [osg-users] Webcam image as texture using OpenCV ‏

[Mourad Boufarguine]

Hi Charlie,

Hi,

 I am looking a way to use the image grabbed from a webcam using OpenCV and
 then use that image as a texture in a osg app.

 Taking the osgmovie example, I already tried to create a subclass of the
 ImageStream class but Im a little lost trying to do it this way so far I
 already know how to convert an IplImage to an osg::Image and I'm able to
 take ONE image from the webcam this way, but now I have no idea in how to do
 update the image every 1/30 second to create the live stream.


You need to call the method dirty() whenever a new frame is grabbed to
tell osg to update the texture associated with the osg::image object.

Re: [osg-users] how to setup a simple camera?

[Mourad Boufarguine]

Hi Claus,

You can setup your camera view matrix using :

viewer.getCamera()-setViewMatrix(matrix)
or viewer.getCamera()-setViewMatrixAsLookAt(eye, center, up)

The second one is a good start. For the meaning of the parameters eye,
center and up, ask your friend (google ^^) about gluLookAt.

Hope this helps,

 Do i need to download to download the extensions file or am I missing

 Also while testing VS2010 it doesn’t be appearing to copying the dll and

 the bin folder as reported earlier by someone else on the list.

 I would look at CMake but I don’t have a clue which file to start looking
 at, have tried the latest build of cmake but that still does the same.

 Can anyone give me some clues or pointers on where to look in cmake or
 where the files are copied or locations are defined? I will give it a go at
 figuring out?

 Hi,

 I noticed that osgAnimation::animation::update uses floating point precision 
 rather than double for it's calculations.

 Was there a reason for this choice? I'm experiencing a noticeable loss of 
 precision in my animations at this point.

 Thanks for your help,

Hi David,

Take a look at osgprerender example, it is what you are looking for.

 i know how to set a texture for an object, so what i´d like to know is how
 to access the color buffer target of the viewer´s camera

Re: [osg-users] How to programmatically clear trackball manipulator's mouse queue

Hi Mike,

You need just to set the throw flag of the trackball manipulator to false.
See setAllowThrow method.

 setting Manipulator-setRotation(last_saved_angles), which does reset it ,

 In the running application, a dialogue reports.
 This application has failed to start because libcollada14dom2l-d.dll was
 not found.  Re-installing the application may fix this problem.
 ( Technically, the application isn't installed, I didn't build 'INSTALL'.
  Does this matter? )

 The dll is in the folder
 C:\2010-02-22_OSG\bin\osgPlugins-2.9.7\osgdb_daed.dll,  however,
 libcollada14dom2l-d.dll is in
 C:\OSG_dev\collada \dom\build\vc9-1.4-d\libcollada14dom21-d.dll  (miles
 away)
 This directory \collada\ is at the same level, *but not inside* the OSG
 3rdParty dependencies folder.
 I have an environmental variable COLLADA_DIR= C:\OSG_dev\collada
 Also, have C:\OSG_dev\collada \dom\build\vc9-1.4-d\ in PATH variable.
 I tried copying the DLL to C:\2010-02-22_OSG\bin\osgPlugins-2.9.7 - but,
 didn't help.


 The minimal slide contains two things, and I don't think is the cause of
 the problem:
 1.  The title which displays and handles as normal,
 2. The DAE model (not) - which of course doesn't appear.

 I would be grateful for any ideas what might be going wrong here, please?

Re: [osg-users] Setting Camera Properties

Hi Yashodhan,

Since you see the objects in the right place, I think the problem is not the
camera pose. Can you send some screenshots so we can understand the problem
? Do you use osgART ? if not, how did you setup the HUD containing the video
?

 I am using the Single Point Active Alignment Method developed at the

 Works fine for me. I don't think that osg does any magic about looking up a
 plugin directory.

 Is the plugin in an accessible place?

 It needs to be in any one of:

 The .exe directory,
 a directory in the PATH environment var, or the current directory

 Just look at the module load messages in the debug output window of VS to
 see of the plugin is being loaded. If it is then either the font file is
 buggered or your build of freetype is screwed up.

 Hi All,

 I've been beavering away for the last two weeks on addressing issues

 concentrating on the stability side clearing up a long standing but

 refactoring osg::Observer class and that parts of osg::Referenced that
 it touches, as well as refactor of the way that recursive mutexes are
 setup in OpenThreads.  I don't have time to go into the details of all
 the changes, but in general they shouldn't affect the build or runtime

 Given how many crucial parts of the OSG I've been refactoring there is
 quite a bit of scope for regressions in build across platforms and
 runtime.  I have tried by best to make the carefully with cross
 platform build and runtime in mind, but I'm not machine, I can make
 mistakes, so please assume that I might have and test thoroughly :-)

 If things go well I'll tag a 2.9.7 tomorrow, and then get back on the
 horse of merging more of the pending submissions.

 Collada requires, part of boost, libxml2 and iconv.

 I found this link:

 https://collada.org/public_forum/viewtopic.php?f=12t=1221Where iconv,
 libxml2, pcre and zlib is built with 64bit.

 So, that should now make the list just about complete. Building the part I
 need from boost in 64 bit should not cause problems I hope. jpeg, zlib, png
 can easily be built from code. I hope this goes for FreeType too, not there
 yet.
 This really was more of a mess than I anticipated.

 I heard that according to steam (which current connects to quite a few
 window pc:s around the world) that the number of 64bit installations (due to
 windows7) is increasing exponentially, so this means that we will soon leave
 the 32bit world of applications.
 Maybe we will be able to build these things without problem, just when all
 other platforms has moved over to 128 but ;-)

 After few research on this forum, I have read that my solution is to
 compile all osg library (and plugins) myself, so I did, and that works.

 My question is now about the dependancies. When I want to load a mesh (.ive

 dependancies. But I have the could find plugin to read objects from file
 ...ive message. The plugin was compiled and is present in
 osgPlugins-2.8.2/osgdb_ived.dll directory. I am pretty sure this error comes
 from an incompatibility with zlib1d.dll because the osg binary dependancies
 are also available on VC2005 SP1, and not on VC2005 SP2.

 What do you think ? and If I am right, how to get the VC2005 SP2
 dependancies ?
 Does any one had already this problem ?

 If I write this image to file, it works great, I have my balance in the

 image-allocateImage(osgViewer-width(), osgViewer-height(), 1, GL_RGBA,

 camera-attach(Camera::COLOR_BUFFER, image.get(), 0, 0); --
 camera-attach(Camera::DEPTH_BUFFER, image.get(), 0, 0);

 After that I get the image depth_buffer.png, but this isn't correct, is it?

 The texture looks like this, is it correct?

// creates the texture for the shadow map
texShadowMap = new Texture2D;
texShadowMap-setInternalFormat(GL_DEPTH_COMPONENT);
texShadowMap-setShadowComparison(true);
texShadowMap-setShadowTextureMode(Texture2D::LUMINANCE);

texShadowMap-setWrap(Texture2D::WRAP_T, Texture2D::CLAMP_TO_BORDER);
texShadowMap-setBorderColor(Vec4(1.0, 1.0, 1.0, 1.0));

 What am I doing wrong in this function?

 The difference is that the BMP plugin does not need any additional DLLs
 (other than the plugin itself of course) but the PNG plugin does (something
 like libpng13.dll). So I suspect you don't have this DLL.

 This DLL is part of the 3rdParty dependencies, so you either have it
 already (if you compiled OSG from source) or you need to download the
 appropriate 3rdParty dependencies for your version of Visual Studio. See
 this page:

 http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies

 You could then copy all the DLLs from your 3rdparty\bin folder to your
 OpenSceneGraph-2.8.2\bin folder so it will be found when osgDB loads the PNG
 plugin.

 Hope this helps,

Re: [osg-users] Trouble porting to vs2008, heap corruption

Hi Stefan,

Commenting the line _vertices-unref(); (line 276 in VertexGeometry.cpp),
seems to solve the problem for me. I think you do not need to unreference
_vertices manually.
Besides that, I got some weird behaviour with some examples using multiple
screens, calling _viewer-setUpViewOnSingleScreen(0) in the constructor of
sx::Scene seems to solve this.

 No it doesn't, symbol mangling isn't different between debug/release

 (though that might be a handy option)

 You won't get linker errors unless you've got methods or functions
 deffed in/out depending on your build config.

 Maybe we should add some funcs to the OSG libs, based on the config
 to stop beginners accidentally mixing builds.

 Mind you the error message from mixing release/builds is different
 from the OPs screen shot. It usually says something about a memory

Re: [osg-users] broken osgconv.exe

[Mourad Boufarguine]

Ted,

I downloaded the osg precompiled package you are using
(openscenegraph-all-2.8.2-win32-x86-vc90-Release.zip),
and I checked that indeed, the osgdb_ive.dll depends on a zlib1.dll that was
compiled with VS 2005 SP1 (which is weird). I presume it is also the case of
libpng, curl and tiff.

So, to move on, you have to recompile osg from the sources using the vc90
dependencies, or install the VC++ 2005 redistribuable packages (there are
two if my memory serves me right ), I think you didn't install the 2005 *SP1
* redistribuable package
(http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647displaylang=en)
.

Regards,
Mourad

 Yes, I think I resolved finding the 3rdparty dependencies. But for some
 reason, the osgdb_xxx pluggins listed in the last e-mail:

 osgdb_gz
 osgdb_curl
 osgdb_ive
 osgdb_png
 osgdb_tiff
 osgdb_tiffd

 dependencywalker shows that these pluggin dlls are still looking for
 MSVCR80.DLL  *and* MSVCR90.DLL

 And the other pluggins can't find MSVCR90.DLL.

 bizarre.

 thanks,
 t



 Well, I tried dependencywalker.com and opened up the pluggins.

 I just tried it with the zlib and png dlls contained in VisualStudio 9
 (2008) SP1 prebuild dependencies (
 http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies),
 and I found that the release versions were compiled with the 9.0.30729
 runtime, which is actually 2008 SP1. The debug version, though, was
 compiled with the 9.0.21022 runtime , which is the 2008 runtime. The zlib
 is used in both ive and gz plugins. I don't see  how you get the message
 about the 2005 runtime dependency. Double check in the output window of VS
 that the zlib and png dlls that are actually loaded are the good ones.

 There is no callback mechanism for catching calls to dirty();

 Perhaps you could use an update callback that checks on each new frame
 whether the modifiedCount has changed since the last frame and then do
 your image processing then.

 Or just move the image processing down onto the GPU, the GPU is far
 better for doing image processing than the CPU so you'd likely gain in
 performance.

 Robert.

Re: [osg-users] Does anybody know how to include OSGViewer using MFC?

[Mourad Boufarguine]

Hi,

There is an example called osgViewerMFC that may help you. You need to check
the BUILD_MFC_EXAMPLE option in CMake.

[osg-users] Image update in ImageStream objects

[Mourad Boufarguine]

Hi All,

When using an ImageStream object (using ffmpeg, gif, quicktime... plugins
for instance), is there a way to catch the image uptade event without
messing with the plugins source code ? I am willing to apply image
processing algorithms on video streams and I want to intercept new images
to do the processing only on new images.

Cheers,
Mourad

Re: [osg-users] Warning: Could not find plugin to read objects from file *.jpg

[Mourad Boufarguine]

Hi James,

It is most probably a side-by-side problem. If you are using the precompiled
binairies provided here
http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies ,
make sure you have installed SP1 for VS2005. These binairies are compiled
using VS 2005 SP1. To be sure, you can use the dependency walker (
http://www.dependencywalker.com/) to check the side-by-side configuration of
osgdb_jpeg.dll.

  This is my first time building OSG and everything went well in Linux but
 I am having a problem in Windows.



 Building: OSG 2.8.2

 OS: Windows XP

 Compiler: Visual Studio 2005 Professional



 The build seems to go through okay and I do have the osgdb_jpeg.dll in the
 plugins directory but I still get the warning when loading a JPEG texture.
 I also built the osgd_png.dll and those textures are loading without any
 problems.



 Any help pointing me in the right direction is appreciated.



 Thanks,
