Re: [osg-users] unknown Quicktime SDK error...
Well, on the other pc there was an old version, but I upgraded it because of another error code. Currently I have the last version becuase quicktime player upgraded itself by internet, so I think it downloaded latest version available...I guess. I also tried to play movies with the player and it works, anyway, I can play them also within my osg application, so the plugin is working fine, despite of that unknown error... I just wonder what that error means. Regards.

This is bit of backward solution to your transparent object problem - you aren't setting up your scene graph correctly, you should be setting the transparent subgraphs to fall into the transparent rendering bin via: stateset->setRenderingHint(osg::StateSet::TRANSPARENT_BIN); This is how the OSG has managed transparent state since the turn of this century.

Lost me there, there are lots of postings on lots of topics, some mention Camera pre/post draw callbacks. As general note, integrating other OpenGL code with app can be done via custom Drawable (as per osgteapot example), via pre/post draw callbacks, via custom GraphicsOperations that you attach to the GraphicsWindow/GraphicsThread, or just in the main loop if you are running single theaded. The advantage of using subclassing OSG centric methods for adding your OpenGL code is that it can help manage the threading for you and ordering. Robert.

Re: [osg-users] OSG, VR Juggler, and multiple render threads...
Hi Doug, There are number of hoops one has to jump through to do safe multi-threading with the OSG, osgViewer does these all for you, while SceneView knows nothing of it and requires higher level classes to handle it. osgViewer itself does use SceneView so does illustrate that it is possible using SceneView so you could possible use this as guide. Personally I'd recommend that VRJuggler just use osgViewer for creating the windows and cameras as per the configuration required by VRJuggler, this way you can take advantage of all the threading models that osgViewer provides in a way that is known to be thread safe. Another key advantage of adopting osgViewer is that problems you see will be much more reproducible by others who don't use VRJuggler. For instance you could create a scene that uses a ClearNode and run in standard OSG examples, and if the problems exists then I and others can look into it. With the current state of play, trying to help diagnose what might be up would require a massive time investment in getting VR Juggler installed, learning about it, setting up the case that reproduces the problem, then stepping through to see where the problem lies. The alterntaive of trying to debug this stuff remotely with even knowing all the VRJuggler code is no mean feat either - there are many things that VR Juggler could be doing wrong w.r.t multi-threaded set up of the OSG, or it could a problem on the OSG side. Trying to sort it out this way would again require a huge investment of time all round. I'm afraid I'm certainly too over stretched to undertake such a process. One of osgViewer core goals is making multi-thread, multi-channel usage of the OSG straight forward, hiding all the subtle details and thread synchronization that is required. I'm not familiar with VR Juggler, but I would have though it should possible to replace the existing SceneView framework with a osgViewer::Viewer object and have the Viewer's windows and cameras all set up according to VR Juggler configuration.

Or am i missing something here? To do multi-threading you need control a proper implementation of makeCurrent, releaseContext, without these the various threads can't get access to the graphics context. GraphicsWindowEmbedded doesn't support these as it doens't actually know anything at all about the graphics context, it rather is facade that does nothing but kid osgViewer::Viewer that its OK to go ahead a do rendering on it - but does mean that it can only be used in a constrained way. > I'm using SDL for window and input handling and read in: > http://www.mail-archive.com/[EMAIL PROTECTED]/msg12744.html > > about a GraphicsWindowSDL class, is it going to be submitted to SVN? Personally I wouldn't recommend SDL for windowing for serious 3d graphics applications, its just way too limiting - its really just designed for single threaded, single context apps. I'd recommend using SDL it for cross platform audio and gamepads/joysticks and use the OSG's native Window support to manage windowing. As for implementing a GraphicsWindowSDL, this isn't possible to do because SDL just doesn't expose enough basic windowing functionality to do what a full blown GraphicsWindow requires. I know this because I had a go at writing it when I developed the osgviewerSDL example, I'm afraid I came away with a much lower view of SDL windowing capabilities.

Hi Doug -- Just thinking of this in OpenGL terms, the dreaded "blank screen" can have many many causes. One possible explanation: The cull traversal on one of the displays randomly thinks that everything is culled. This could be due to a configuration issue for the camera controlling that display, the modelview/projection matrices are bogus and/or the view volume used during the cull traversal isn't set correctly. You might consider hacking the code to dump such information out per frame. Yes, it will generate gobs of output, but if you do a short run and see a flash, then examine the debug output, any one-frame irregularities should jump out at you. If nothing shows up, then the problem is somewhere else. The other thought I had relates to the ClearNode. Does the problem go away if you eliminate the ClearNode and just let SceneView do its own clearing? -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Bingli,
I suspect you've got "pure" CLR support (/clr:pure) selected in your project
configuration, which tells the compiler you're only using managed code. You
need to have standard CLR support (/clr) selected to compile against the
native code of OSG. The setting is in the General section of your project's
Configuration Properties.

We'll its RenderStage that SceneView uses to clear, and its ClearNode that just adjusts the default settings of the clear that RenderStage does and done from with the cull traversal. In effect it'll be exactly the same code doing the clear, the only difference is that how the values are set - one from the defaults provided by SceneView, and one from the scene graph.

Re: [osg-users] ??: A simple question from an learner.
Hi Bingli,
I suspect you've got "pure" CLR support (/clr:pure) selected in your project
configuration, which tells the compiler you're only using managed code. You
need to have standard CLR support (/clr) selected to compile against the native
code of OSG. The setting is in the General section of your project's
Configuration Properties.

OSG can definitely be used with WinForms. It sounds like you're running
into some project configuration issue though. If you can post your
error messages we might be able to provide better help.

Re: [osg-users] Getting OSG to display on second screen
Hi Peter, GraphicsContext::ScreenIdentifier struct has the displayNum, screenNum and hostName member varaibles. GraphicsContext::Traits subclasses from ScreenIdentifier. You can set the displayNum, screenNum and hostName on a Traits then request the creation of the graphics context that fullfills these traits via osg::GraphicsContext::createGraphicsContext(traits); I'm not sure where the best place for initializing of ScreenIndentifer from the DISPLAY env var under X11 system. Potentially it could be done in the default constructor of ScreenIndentifier, although I'm wary of this as it perhaps is a bit overzelous for apps that don't wish to honour the DISPLAY variable, and opt in scheme might be more friendly. Moving the reading of DISPLAY into osgViewer::View::setUp* might be better, and allow OSG examples and default set up viewers to honour DISPLAY, and leave it up to end users to decide whether to opt into honour the DISPLAY variable if they wish for Traits they set up themselves. Either way adding a convenince method into ScreenIdentifier to read the DISPLAY variable is the first step. Robert.

Does mouse control still work after quiting? osgViewer's GraphicsWindowX11 doesn't take control from the window manager, all it does is set the keyboard focus to the window that it creates. If things like the mouse isn't working after quitting then it sounds very much like your window manager is broken. What OS/Window Manager/OpenGL driver version are you using?

Re: [osg-users] View/Projection/ModelView matrix not applied?
Hi again... Two things of which the first is of higher priority... 1. To make the ModelView matrix match the osg definition (z-up) how would you recommend that I calculate the modelview assuming that only the Camera is known in a preDrawCallback, just so that I don't make any assumptions that can later be changed in some other part of the system? I can get the ViewMatrix, I can also get the MatrixList (of all matrices above the camera in the scenegraph), but to match osg and to make it as flexible as the rest of osg, how would do this? 2. Regarding GraphicsContext, assume that I do need access to a graphicsContext in a PreRender, how can I take control of that Context avoiding any race condition? Now, Im not sure where I get the hang, but it does have something to do with the fact that Im accessing OpenGL when I should not... Eventhough, when I get into the PreRender callback the Context is active. so a simple makeCurrent() would not work.

Re: [osg-users] OSG, VR Juggler, and multiple render threads...
hi doug, lots of good ideas in the thread so far. my gut feeling is similar to yours, that it is a threading thing, but it's hard to diagnose from a distance. :) one thing you could do is expressly set each channel's clear color differently, to try to see if state is leaking from one context to another. so, set one to red, another blue, another green, and see if when you see the flash, that maybe the color might inidicate which (or if) another context's state is leaking. if so, it implies some sort of thread confusion, that for a moment, one set of state is being applied in the wrong context. other than that, you could try logging clears from the clearnodes, or running through a debugger to see what happens in each thread wrt what gl calls are issued, and when. you should be able to see a context made current, and a set of initial state happen (including clear color, if you've got a clearnode), and then the actual clear. the mac opengl debugger makes this sort of process relatively easy. anyway, just a few thoughts for a hot friday afternoon. good luck! bob bob kuehne founder and ceo - blue newt software, llc [EMAIL PROTECTED] - 734/834-2696 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi~, I am trying to use osg::VertexBufferObject for speed rendering a dynamic changing geometry. It is suggested to use DYNAMIC_DRAW for the usage flag, but osg seems having no way to change _usage. Do I need revise and recompile osg code for DYNAMIC_DRAW usage?

Re: [osg-users] How to change _usage of BufferObject
Hi Xingou, In the SVN/2.1.x series there is a BufferObject::setUsage(GLenum) method. There is also better management of VBO's in the osg::Geometry and osg::Array classes. Robert.

[osg-users] osgDotNet: Managed Wrappers Traits fix time estimate
I am using C# under Windows XP and thinking about using OpenSceneGraph. I want to have the Viewer use a Panel on a Form rather than create its own Window. The osgDotNet: Managed Wrappers for OpenSceneGraph have a problem with accessing member variables and this affects GraphicsContent::Traits. I saw that Traits was put on the ToDoList about a month ago. Is there an estimate on when Traits is going to be fixed?

[osg-users] texture1D example
In trying to solve my texgen issue, I decided to play with the texture1D example. I noticed that it defines an AnimateStateCallback which is supposed to toggle the texgen mode between OBJECT_LINEAR to EYE_LINEAR every second. Whenever I run the example on cow.osg, the texture seems fixed regardless of how I rotate it. It's as if the texgen computes the coords once and never updates them. Is there something missing in the example that, or should it really work that way?

Re: [osg-users] osgDotNet: Managed Wrappers Traits fix time estimate
Hi Zachary,
You can use the GraphicsWindowEmbedded class in conjunction with an
osgViewer to use the .NET wrappers. I'm attaching an example control that
uses Tao that seems to work for me pretty well.
If the particle system/transform issue that I posted on the osgDotNet trac
website gets fixed, I'm very happy so far with the wrappers. Just about
everything sensible I've tried "just works" the way I thought it should.
Thanks!

[osg-users] Problems shading multiple objects
Hello,
i've developed a simple test environment for a dot3 shading
test on a simple plane object. All works fine until yet.
Now i've create a second object, based on the geometry
values of the first one with a new second stateSet object.
If i place this second object with an attitude transform in
the near of the first one, on both objects the shading
results are exactly the same. This could not be correct,
because if i place a lightsource between both objects,
the reflection are exactly the same. This is what i do:
//create first object
osg::Group* rootNode = new osg::Group();
osg::Geode* quadNode = createQuad(osg::Vec3(0.0f, 0.0f, 0.0f), 10.0f);
osg::PositionAttitudeTransform* pos1 = new osg::PositionAttitudeTransform();
pos1->setPosition(osg::Vec3(0,0,0));
pos1->addChild(quadNode);
//create 2nd one (does nothing special,
//only copies the geometry data and add
//to a new geode)
osg::Geode* quadNode2 = rebuildQuad();
osg::PositionAttitudeTransform* pos2 = new osg::PositionAttitudeTransform();
pos2->setPosition(osg::Vec3(20,0,0));
pos2->addChild(quadNode2);
//add to root
rootNode->addChild(pos1);
rootNode->addChild(pos2);
//create root stateSet
osg::StateSet* rootState = rootNode->getOrCreateStateSet();
rootState->setMode(GL_LIGHTING, osg::StateAttribute::OFF);
..
As you can see, no magic stuff for object creation and position.
Now the source fragment for shader creation which is executed once:
osg::StateSet* bumpMapState;
osg::Program* bumpMapProgramObject = new osg::Program;
osg::Shader* brickVertexObject =
new osg::Shader( osg::Shader::VERTEX );
osg::Shader* brickFragmentObject =
new osg::Shader( osg::Shader::FRAGMENT );
bool ok =
loadShaderSource( brickVertexObject, "dot3.vert" )
&&
loadShaderSource( brickFragmentObject, "dot3.frag" ) ;
if(!ok)
{
std::cout << "Couldn't load shaders" << std::endl;
return -1;
}
bumpMapProgramObject->addShader( brickFragmentObject );
bumpMapProgramObject->addShader( brickVertexObject );
// bind render attributes for BT-Values
bumpMapProgramObject->addBindAttribLocation("tangent",
osg::Drawable::ATTRIBUTE_6);
bumpMapProgramObject->addBindAttribLocation("binormal",
osg::Drawable::ATTRIBUTE_7);
// set shader hooks and bind it to application sources
osg::Uniform* lightPosU = new osg::Uniform("LIGHT_POSITION",
osg::Vec4(lpos.x(), lpos.y(), lpos.z(), 1.0));
osg::Uniform* cameraPosU = new osg::Uniform("CAMERA_POSITION",
osg::Vec3(posV[0], posV[1], posV[2]));
osg::Uniform* normalMapU = new osg::Uniform("normalMap",1);
osg::Uniform* baseTextureU = new osg::Uniform("decalMap",0);
osg::Uniform* ambientU = new osg::Uniform("matAmbient", osg::Vec4(0.0f, 0.0f,
0.0f, 1.0f));
osg::Uniform* diffuseU = new osg::Uniform("matDiffuse", osg::Vec4(0.8f, 0.8f,
0.8f, 1.0f));
osg::Uniform* specularU = new osg::Uniform("matSpecular", osg::Vec4(0.8f, 0.8f,
0.8f, 1.0f));
lightPosU->setUpdateCallback(new updateBumpShader());
cameraPosU->setUpdateCallback(new updateShaderView());
Now bind Shadersources explicit to object StateSets,
separated:
for(int i=0; i<2; i++)
{
if(i==0){
bumpMapState = new osg::StateSet();
quadNode->setStateSet(bumpMapState);
}
else if(i==1){
bumpMapState = new osg::StateSet();
quadNode2->setStateSet(bumpMapState);
}
bumpMapState->setMode(GL_CULL_FACE,osg::StateAttribute::ON);
// bind variables
bumpMapState->addUniform(lightPosU);
bumpMapState->addUniform(cameraPosU);
bumpMapState->addUniform(normalMapU);
bumpMapState->addUniform(baseTextureU);
bumpMapState->addUniform(diffuseU);
bumpMapState->addUniform(ambientU);
bumpMapState->addUniform(specularU);
// bind attributes
bumpMapState->setAttributeAndModes(bumpMapProgramObject,
osg::StateAttribute::ON);
Then do texture stuff ...
This was all ...
}
Know's anyone what i do wrong?
Thanks for any help,
Best regards,
Chris
