[osg-users] Problem: CompositeViewer doesn't work with Stereo
Hello, I use the osg composite viewer and I try to use some stereo mode, i.e. CHECKERBOARD, HORIZONTAL_INTERLACE or the VERTICAL_INTERLACE. But this modes don't work with the composite viewer. I use osg 2.8. I guessed it is a problem in my application, so I tried the osgcompositeviewer example with these stereo modes. Also these didn't work. Any ideas? Cheers Martin -- Schon gehört?

Re: [osg-users] WindowManager root
Jeremy Moles wrote: I'm curious why you want this? There might be a better way to get the results you're seeking w/ existing codestuffs. That's the reason why I was asking ;) Basically I have my own layer of objects that encapsulate osg ones. I have a Scene Manager that is not dependent from the viewer. This means my vewer, that encapsulates the osg viewer, calls a getRoot() method of my Scene Manager to get the osg root node and attach it to the osg viewer. I would like my Scene Manager to be independent from the viewer even with widgets. So, which type of osg object should I store in my Scene Manager so that I can just pass it to the viewer to see the osg widgets. Moreover the osg object that I store into my Scene Manager should be able to add other osg widgets at runtime.

[osg-users] Cameras and FBOs
Hi there! Is there any way to explicitly pass an osg::FrameBufferObject to a Camera, so the camera renders into it? or, using FRAME_BUFFER_OBJECT as the Camera RenderTargetImplementation and attaching textures/images/buffers to it, is there any way to get the FrameBufferObject the camera is using from a Camera draw callback? or, even not getting it, is there a way to bound the FrameBufferObject of this Camera?

Re: [osg-users] Transparent Viewers/Close Viewer
Hi Andrew, Do you mean multiple View's withing a CompositeViewer? While it's technically possible to add a osgViewer::Viewer to a CompositeViewer since Viewer subclasses from View, it's not the intended usage - you should use View's instead. In terms of closing a View, does this View have it's own GraphicsWindow(s)? If not then just setting the View's Camera's NodeMask to 0 will switch if off and set it to 0x to switch it back on again. If the View does have it's own GraphicsWindow then you'll need to close the window and switch off the rendering via the NodeMask - although I've never actually tried specifically this so you'll be working on the bleeding edge. The other approach is to simply removing the View from the CompositeView and add back in a new one when you need it. The NodeMask route is lightest weight route though and is what I'd do if it's possible. Robert.

Re: [osg-users] Problem: CompositeViewer doesn't work with Stereo
Hi Martin, The rendering backend is identical between Viewer and CompositeViewer so both are fully capable of doing stereo. I presume the issue comes from the DisplaySettings hints used to pass in the stereo settings. With CompositeViewer each View can have it's own DisplaySettings object so you can set this up independantly.

Re: [osg-users] Culling mask problem.
Hi Miguel, The traversal is from top down and will stop traversing if the NodeMask of any node is 0, so it'll stop at transform1 is it's NodeMask is 0. If you want to get down to geode2 then you'll need to set the NodeMask of transform1 to a none zero mask. I don't know what you are trying to achieve, but at a guess you might be trying to toggle geode1 and geode2 independently, and if this is the case then you should be moving the NodeMask manipulation to the geodes.

Re: [osg-users] Cameras and FBOs
Hi Javier Is there any way to explicitly pass an osg::FrameBufferObject to a Camera, so the camera renders into it? Yes you can use a framebufferobject as a render to texture target, checkout the osgprerender example. If you want to use the result of your render in your main app i.e. read the pixel info for some sort of gpu compute, then you need to use a pbuffer for your main viewer. You set it up something like the following Set pbuffer in the graphics traits (used to create your context) to true Set the viewers renderTargetImplementation to FRAME_BUFFER_OBJECT Attach an image as the cameras color buffer. Now when you render the result will end up in the image and could be saved to disk if you like.

Hi Robert, Thanks for your reply. Yes, odd things are certainly happening. From what I am observing it would be more sensible to create the camera at start time. However I am still confused by why this corruption occurs. The osgViewer::Viewer is running in CullDrawThreadPerContext mode.

I was assuming, that because of the End Rendering Dispatch Barrier that when osgViewer:frame returns all rendering activity should have finished. Is this correct? I assume from your comments that nodemask is honoured on cameras added by addSlave as well as those added as nodes in the graph. That is useful to know. I have made some notes on concurrency in the various threading models. I would be grateful if you could comment on them and correct me where necessary. I will then put them in the wiki. I apologise in advance if they are utter nonsense, but this stuff is a bit difficult to follow from the code!

Re: [osg-users] Camera control in osgvisual
CIGI uses UDP so updating osgVisual to use CIGI shouldn't be an issue in terms of performance. Effectively you'd be replacing one UDP implementation with another that uses an industry wide standard for the packet description...a big plus IMO. Like I stated earlier, CIGI is used by most commercial IG vendors so performance is more than adequate. The main advantage of CIGI is that it provides a common interface for a simulation host so that you can run the same host on different IGs on the back end. We just swapped out an old IG for a newer one with minimal changes to our host software. If osgVisual supported CIGI, I can guarantee that you would open it up to a much wider audience of users...at least in the simulation industry for sure. Having an OpenSource solution here would be a benefit. Right now, the software that currently ties CIGI to OSG for multi-channel IG purposes is proprietary in nature. VT-MAK is one such company that comes to mind... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Torben Dannhauer Sent: Sunday, February 13, 2011 4:48 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Camera control in osgvisual Hi Tedzini, I'm not very familiar with CIGI, but it seem to be a communication library for communication with the sim-host.

[osg-users] Mouse cursor won't redraw
Hi,
I'm having a mouse cursor/ windowing issue that I'm hoping someone has run
across. I'm changing the mouse cursor via the setCursor() method copied below
in my Windows App's preframe function. It works, but the cursor doesn't
actually redraw without some sort of mouse input.
I can't seem to find a way to trigger this repaint without mouse movement. I've
tried the RequestRedraw() and RequestContinuousUpdate() methods on the window
with no luck. I also tried sending repaint messages to the Windows view as well
as spoofing the mouse movement.
I'm sure I'm missing something. Any insight is appreciated.
Thank you!
Cheers,
Garrett
Change Cursor:
Code:
osgViewer::Viewer::Windows windows;
mViewer-getWindows(windows);
for(osgViewer::Viewer::Windows::iterator itr = windows.begin(); itr !=
windows.end();++itr)
{
(*itr)-setCursor(osgViewer::GraphicsWindow::WaitCursor);
}

Re: [osg-users] Camera control in osgvisual
Boeing's multipurpose viewer (MPV) was designed to simply be a test harness for the CIGI protocol. It's a far cry from it being used as a general purpose IG. I've downloaded MPV from the CIGI site and played with it. It does use old OSG stuff (osgProducer). I had to modify it to use the newer osgViewer stuff. It also does not support osgTerrain type or round earth geocentric databases last time I checked. Lastly, the largest deficit IMO, is that it doesn't support multi-channel rendering with OSG...a big drawback. It does support multi-window rendering on one machine but not true multi-channel (i.e. a channel per box). In short, it would require a great deal of modification and development to bring it up to a point that it could be used as a commercial IG. One might get closer to the goal by making osgVisual talk CIGI... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Philip Taylor Sent: Sunday, February 13, 2011 6:49 PM To: 'OpenSceneGraph Users' Subject: Re: [osg-users] Camera control in osgvisual Last time I downloaded the CIGI source code it came with an OSG application MPV aka Multi-Purpose Viewer http://cigi.sourceforge.net/ Looking at the WIKI page at the above site, it states that it requires OSG 2.4 but will work with 2.6 - that makes it quite an old implementation but MPV is only supposed to be an example, with limited functionality.

Hi Shayne, I totally agree to you, but as I said I have to take care on my regular job (medical research and doctorate student in medical science), so it will take a littel bit to accomplish it. Today eent I plan to tag osgVisual 0.6 and i hope to finish the documentation/wiki to the new features till the end of the week. The next task I have to solve is terrain modification (flattening terrain and/or curting wholes in it) to allow to insert airport models with a flat runway. After that I would like to dive into CIGI. I totally agree that currently osgVisual is only useful for very few people wich can use the proprietary VCL implementation. CIGI would be great there - expecially because VCL only supports doubles currently, so it is tricky to update object labels etc. ;) Thank you!

Re: [osg-users] Cameras and FBOs
Hi Javier Sorry, I see what you're asking now, what you actually want to look at is osgUtil::RenderStage::runCameraSetup In this function you will see how a cameras BufferAttachment list is used to create relevant fbo etc. The created fbo is stored in the _fbo variable of the RenderStage. I think this stems back to the days of osg using producer as it feels rather like this sort of thing should be happening in the viewer. I think that's why it's quite difficult to follow. What are you trying to achieve with the fbo once you have it?

I know I can use a FBO to do render to texture or to an image or to a render buffer. The question was if I can have access to the FBO used by the camera, either by passing a FBO pointer to the camera or getting a pointer to the FBO of the camera. I have looked for it in the source code, but I found no way to do it. Thanks anyway. I think I will try by adding an FBO to the StateSet of the part of the scenegraph under the camera.

Yes you can use a framebufferobject as a render to texture target, checkout the osgprerender example.

After more checking I can see that my finding that test number 4. was not producing the corruption is false. This is due to the fact that the debugger was stopping all threads. If I put breakpoints on two consecutive (nearly) instructions, then the corruption appears again. I now assume that the corruption apppears for one frame in all cases when the rendering order is set to POST_RENDER.

So, along the same lines... One of these views contains a windowmanager that controls my 2D GUI that I want on top of the other views. Since my GUI is an L shape, with the main 3D view surrounded by the L, placing the GUI on top of the other views blocks off those views (since the view is a square), but placing the other views on top of the GUI view prevents me from placing GUI elements above those views...

[osg-users] extending Blender with pbuffer/rendering to texture
Hi,
I have somewhat similar questions to recent FBO question,
but not quite, so I would ask in a new thread.
I try to extend Blender with osg rendering ( just because osg does many
things better than Blender namely I use osgPango to render dynamically
text).
First - it is fairly easy to create in osg app pbuffer
by
setting
traits-pbuffer = true;
and then
osg::ref_ptrosg::GraphicsContext pbuffer =
osg::GraphicsContext::createGraphicsContext(traits.get());
if (pbuffer.valid())
{
osg::notify(osg::NOTICE)Pixel buffer has been created
successfully.std::endl;
osg::ref_ptrosg::Camera camera =
createOrthoCamera(WINDOW_WIDTH, WINDOW_HEIGHT);
camera-setGraphicsContext(pbuffer.get());
osg::GraphicsContext* context = camera-getGraphicsContext();
camera-setViewport(new
osg::Viewport(0,0,WINDOW_WIDTH/*traits-width*/,WINDOW_HEIGHT/*traits-height*/));
GLenum buffer = pbuffer-getTraits()-doubleBuffer ? GL_BACK :
GL_FRONT;
camera-setDrawBuffer(buffer);
camera-setReadBuffer(buffer);
viewer.setCamera(camera.get());
}
set viewer data,
set render callback
and make it viewer.renderingTraversals(); to perform rendering once.
after which it is possible to read glReadPixels and apply them as texture.
Obviously, Blender has another context and
osg::DisplaySettings* ds = osg::DisplaySettings::instance().get();
traits-width = WINDOW_WIDTH;
traits-height = WINDOW_HEIGHT;
traits-pbuffer = true;
osg::ref_ptrosg::GraphicsContext::Traits traits = new
osg::GraphicsContext::Traits(ds);
osg::ref_ptrosg::GraphicsContext pbuffer =
osg::GraphicsContext::createGraphicsContext(traits.get());
causes subsequent attachment to blender texture to fail.
I tried to notify pbuffer traits with
traits-setInheritedWindowPixelFormat = true;
osg::ref_ptrosgViewer::GraphicsWindowWin32::WindowData wdata = new
osgViewer::GraphicsWindowWin32::WindowData( GetActiveWindow(),false );
traits-inheritedWindowData = wdata.get();
but to no avail - I still have problems ( and BTW I found that code in
windows pbuffer won't use inherited data - it will created temporary
window).
so the question is - if I use osg to render to pbuffer in complex OpenGL
application, how to make that contexts problems does not occur?
I seen in replies for osg/OpenGL apps integration that FrameBuffer ( pbuffer
) is easiest way to go.
but in my case I did not got working solution.
so what should be changed to get rendering to pbuffer with osg in outside
app ( even if it requires to make changes in core osg - what - to get rid of
makecurrent or instead keep track of makecurrent etc?).
Best regards
Sergey
