[osg-users] Shader Problem
Hi all, Are there any ways to remove the shader during runtime? I've tried the removeShader function but the effect of the shader is still applied to my models (e.g tank) i.e. the appearance of the models do not go back to the state before shader is applied.

Re: [osg-users] (no subject)
Hi Pecoraro thank to spot the bug please send your submissions on osg-submissions the next time. after review the original code, at line Optimizer.cpp:1561 lod-getNumRanges() is used to know how many iteration will be done in the for loop, and getNumRanges have to be equal to getNumChild, so lod-getChild(i) at line 1563 is not the problem. Perhaps you LOD is not synchronised (num of children and num of range are not equal)i don't know why or how is possible. Anyway, in a case of a PagedLOD, only the code of LOD is used, so not special case for a PagedLOD. correct me if i'm wrong. Cheers David Callu 2008/6/6 Pecoraro, Alexander N [EMAIL PROTECTED]: I think there is a bug in the osgUtil::Optimizer::CombineLODVisitor - at line 1530 of Optimizer.cpp it does a dynamic_cast on and osg::Node* to osg::LOD* and then at line 1563 it calls getChild(i) (even if getNumChildren() == 0) on the dynamically casted LOD node. This works fine when the node is an LOD node, but when it is a PagedLOD node then it causes in invalid access to the _children vector. I attached a screen shot to show what I mean. This situation would only ocurr when a PagedLOD node was a sibling of an LOD node, which is probably why it hasn't been spotted before. Not sure if this is the accepted way to submit a fix, but anyway I made a fix to the Optimizer code (version 2.4) and attached it to the email.

Re: [osg-users] Shader Problem
hi CG when you remove a shader, osg::Program need to be relinked. this is done by osgUtil::GLObjectVisitor in osgViewer::Renderer::draw method. So this seem can be done at runtime.

Re: [osg-users] osgmovie error message
Hi, Dieter Pfeffer schrieb: I get an application error (The instruction at ... referenced memory at The memory could not be read.) when I stop my application with esc. When I run in debug mode, it breaks in QTUtils.cpp with the message Unhandled exception .. Access violation reading location ... My application has parts of osgmovie included and I can reproduce this message in osgmovied (windows xp, osg2.3.6) when I comment in the function myCreateTexturedQuadGeometry () the line // pictureQuad-getOrCreateStateSet()-setTextureAttributeAndModes(0, texture, osg::StateAttribute::ON); for useTextureRectangle It makes no sense to do this and I don't do it in my application, but I am trying to find out the reason for the application error. You can compare the output of osgmovie when setting the notify-level to DEBUG_INFO, perhaps there's some info what's going wrong. Quicktime does not like to be unloaded from a DLL, perhaps this is your problem. We use a workaround for this: the qt-plugin observes all quicktime-movies and unloads quicktime when the last quicktime-movie-reference got out of scope to prevent the crash-on-exit.

I'm using a RTT and then apply the texture to the object but i'm having some problem for mapping correctly the texture on the object (see capture in attachment). My RTT camera must be similar to my viewer camera, so i've tried to play with the matrix but without success.

Re: [osg-users] Viewer Hanging Problem (Without the main viewer loop)
Hello again, I figured out that there is no hung OSG viewer but a WM_KEYDOWN message processed by the OSG's WindowProc. If you put an OSG Viewer in an MFC window, even if you don't activate OSG manipulators, OSG's Window Procedure is still active and handles messages before your DefaultWindowProc, so if you press ESC key, viewer quits :)) But my question still remains and if anyone thinks that it is a mis-use, please let me know.

Re: [osg-users] bug in last SVN VPB????
Hi David, The tiles in the PagedLOD don't match up perfectly in general. osgTerrain gets them really close, but sometimes you'll see the gaps like you pointed out in your image. osgTerrain uses a skirt around each tile to hide those gaps. If the default skirt is not working out for you, you can use the --skirt-ratio to increase the size of the skirt to hide the gaps. In general, its going to be better to use the GDAL library to process and georeference your imagery and terrain before passing it along to osgdem rather than trying to use the --xx and --yy family of operators to reduce potential georeferencing problems like the image being flipped.

[osg-users] cmake, osgdb_freetype, and OTHER_LDFLAGS for Xcode on OSX
Stephen,
I have been working with Eric Wing here at WWDC to improve the CMake
generator for Xcode when compiling OSG. I noticed your question on the OSG
mailing lists:
* I need some CMake-advice. I found a solution for the linker-error, I**
have to add**
-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:$(SDKROOT)/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib**
to** OTHER_LDFLAGS, then xcode compiles the osgdb_freetype plugin.
But how do I add this option into the CMakeLists.txt-file? I tried #
bugfix for leopard linker bug picking the wrong libgl-lib** IF(APPLE)**
SET(CMAKE_SHARED_LINKER_FLAGS,${CMAKE_SHARED_LINKER_FLAGS}**
-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib)**
ENDIF(APPLE) but this does not work. The OTHER_LDFLAGS remains
untouched.** Can somebody help me here, I looked over the CMake docs
but could not** find any suitable information...*
Did you find a solution? I tried a very similar change that also didn't
work. I tried the variable you had above, and I also tried setting
LINK_FLAGS and that didn't work either.
-Eric

[osg-users] loading thousands of images!
Hi guys, i'm using osg 1.2. I would like to load a lot of images (15000 jpeg files) in memory using an osg:image vector ( std::vectorosg::image), but i receive something like a memory bug when i arrive to load the 400th image (if i load i.e. 380 images i have no problem). Initally i have supposed to load all images (30 kbyte for each image) in a std:vectorosg:image. I have seen that osg:imagestream also exists. What is the difference between image and imagestream? where i can find more information on how to use these classes? Is there a tutorial or example that explain how to use them? I have taken look on quicktime plugin, but both version and topic inside plugin (quick time plugin try to convert video streaming into image, my problem is to load a lot of images!) don't allow me to use it. Also, i have tought to use two separate threads one for image folder loading, and the second for visualize image, but visualization thread is two time faster then loading thread (and i have only a buffer of 400 images available!).

Re: [osg-users] [Depth Buffer rendering]
Hi Mathieu, Sorry I don't have the time to compile and test your code, but I saw the screenshot and it looks like your depth texture gets rendered and applied to the object. What you may need to do is to make sure you set up RTT camera transform exactly as main camera transforms, and texture coordinates are properly generated to span the whole window. In other words I guess that you want to have texcoords match pixel locations in the final output screen. Ie you want texcorrds on the objects to span -1..1x-1..1 range on the output window. Right ? If yes, then you could use simple shader, or add a texgen node to produce proper texcoords for the output scene. This texgen should use EYE_LINEAR coords and its transform should be set to projection matrix of RTT camera and main camera. I am also not sure if seeting your effect camera to RELATIVE_RF gurantees using the same projection for RTT camera as for main camera. One could be sure if he forces this explicitly eg: camera-setProjectionMatrix( viewer-getCamera()-getProjectionMatrix() ); To add texgen node try adding following lines to your code: camera-setProjectionMatrix( viewer-getCamera()-getProjectionMatrix() ); osg::TexGenNode * texGenNode = new osg::TexGenNode; _scene-addChild( texGenNode ); texGenNode-setTextureUnit( 0 ); texGenNode-getTexGen()-setMode( osg::TexGen::EYE_LINEAR ); texGenNode-getTexGen()-setPlanesFromMatrix ( camera-getProjectionMatrix() * osg::Matrix::translate(1,1,1) * // remap -1..1x-1..1 range osg::Matrix::scale(0.5,0.5,0.5) // to 0..1 x 0..1 range ); One final note, it looks like you use cow.osg model. AFAIK this model already contains texgen using SPHERE mapping mode. To avoid conflicts for tests I suggest you use other model. Hope it helps, and no guarrantees, I have no time to verify if everything what I wrote is 100% correct.

[osg-users] Crash in osgViewerWX
hi,
i've used the osgViewerWX example for my program and I'd like to change the
camera view inside the GraphicsWindowsWX class. I've done this:
- I pass the viewer to GraphicsWindowsWX in function wxOsgApp::OnInit().
frame-SetViewer(viewer.get());
gw-setViewer(viewer.get());
And I set the new camera view in class GraphicsWindowWX.
void GraphicsWindowWX::setView()
{
_viewer-getCamera()-setViewMatrixAsLookAt(
osg::Vec3(450.,-450.,1200.),osg::Vec3(450.,450.,0.),osg::Vec3(0.,0.,1.));
}
It works fine, but when I close the program, it crashes and i got this message
in the console window:
'Warning: deleting still referenced object 08E57B70 of tye 'class
osg::Referenced *'
the final reference count was 1189214347, memory corruption
possible.
What am I doing wrong??

Re: [osg-users] loading thousands of images!
Loading a large number of images all at once might be overloading your memory capacity. Even if you can fit all of the images in main memory at once, doing it this way does not scale very well. Google Earth does it this way and it chokes hard when loading larger animations. Remember that even if each of your images is 30K on disk, they are uncompressed in memory after being loaded. The better way is to just load images individually, use them to display, then throw them away. The imagestream class can help with this. I don't have any specific experience with this class but I imagine that it is similar to what I do myself in my application. The fastest path for loading lots of images is to compress the textures and store them on disk in compressed format (that is, ive format). Then, when you are loading images, no processing is needed to display the image. I use this technique in my program, and it is very effective. -Eric On Thu, Jun 12, 2008 at 8:46 AM, Andrea Martini [EMAIL PROTECTED] wrote: Hi guys, i'm using osg 1.2.

Re: [osg-users] Need help getting the osg::ColorMask I previously set
Hi
One things I noticed is you do 'osg::ColorMask mask'. This is wrong you
need this to be a pointer to an osg::ColorMask instance
FYI If you post a question my code won't compile at least provide the
compilation errors...

The above is from osgUtil::Optimizer and shows how the TextureAtlasBuilder
gets the Texture2D StateAttribute. You can use a similar method to get any
StateAttribute. For non-texture state, use getAttribute(), for example, and
of course you don't need a 'unit' parameter.

[osg-users] Composite Viewer with TXP database works?
Has anyone been using a Composite Viewer with multiple views and a TXP database? I have a viewer with a second view that sits in one place within the database. I can add whatever I want to the second view. It works fine unless I call: view2-setSceneData(databasenodes); where databasenodes is a TXP database. The scene comes up in the second view until I start to fly around within the database, then it dies. I'm thinking the TXP plugin has a problem maintaining two views. d ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] New Improved DatabasePager, now with even more threading! Please take a taste today :-)
I'm having a similar issue with DatabasePager::RequestQueue::takeFirst() (osg trunk, Debug build, windows XP VS2005). I'm getting some assertion errors at _requestList.sort (sequence not ordered). Even after adding the updateBlock(). I'm pretty new to this code section, so I'm probably off base here: Is it possible that the state of the databaseRequest objects within the list are being updated (from other threads) during the sort? IE. If the _timestampLastRequest or _priorityLastRequest are changing during the sort, the sort could become unstable. ___ Jim Lynch -Original Message- On Tue, May 27, 2008 at 12:08 PM, Tim Moore timoore at redhat.com wrote: Indeed.

[osg-users] osg::Camera::FRAME_BUFFER_OBJECT, on-screen windows not reflecting rendered image
Hi, I am somewhat new to OpenSceneGraph. For my project we need to render offscreen -- so that overlapping windows do not corrupt the rendered image. We are using osg::Camera::FRAME_BUFFER_OBJECT render implementation, and getting the core behaviour we want, which is to say that we can extract the correctly rendered pixels from the image attached to the camera/frame buffer object. However, I still have two issues, and a question on performance: 1) The on-screen window is not showing the rendered image. Instead it is filled with garbage (or black) pixels. The question is what is the best way to reflect the contents of the fbo image? Should we do as osgprerender example does and create some geometry (osg::Geometry) and then texturemap the image onto the surface, or is there another (better?) way to push the pixels into the framebuffer so that the on-screen window displays properly? 2) using osg::Camera::PIXEL_BUFFER_RTT render implementation crashes on our system. We are running 32-bit Windows XP with dual SLI-graphics NVIDIA 5600 cards. I didn't spend a lot of time on this problem, mainly wondering if others are seeing the same? 3) Question: Any recommendation(s) on ways to increase/maximize performance when using fbo? Here is a code snippet showing how we are currently setting up the fbo: . . . osg::Image * fboImage = new osgImage(); fboImage-allocateImage( width, height, 1, GL_RGB, GL_UNSIGNED_BYTE); wc-cameraPostRenderCB = new WindowCapturePostDrawCallback(wc-getView(), fboImage, NULL); // attach the image so it's copied on each frame. theCamera-attach( osg::Camera::COLOR_BUFFER, fboImage); osg::Camera::RenderTargetImplementation renderImplementation; renderImplementation = osg::Camera::FRAME_BUFFER_OBJECT; // tell the camera to use OpenGL frame buffer object where supported. theCamera-setRenderTargetImplementation(renderImplementation); // set the post render callback theCamera-setPostDrawCallback(wc-cameraPostRenderCB); . . .

Re: [osg-users] New versions of OSG and configuring CMake
I presume you are workng on Windows and change build folder.If you just update from svn you should not be forced to configure again.

Re: [osg-users] Shader Problem
Hi David,
Just found out that the fault lies in my 3D model. Apparently, my shader only
works for 3D models that are in OpenFlt format. It doesn't work for ive fomat.
I've appended my shader code below:
uniform sampler2D tex;uniform float fAmp;
void main(){
vec4 texelColor = texture2D(tex, gl_TexCoord[0].st);
texelColor = texelColor * fAmp;
gl_FragColor = texelColor;}
