Re: [osg-users] VPBMaster failing - build_master.source not loaded correctly.
Ok, I think I am getting close to the source of the issue, so hopefully
somebody may have some ideas.
The problem is occuring because the TerrainTile being loaded from
build_master.source has no color layers and no elevation layer. A manual
inspection of the file shows it does have a color layer so it looks like the
.source file is not being loaded correctly. Next step is to look into the
loading of the file.

Re: [osg-users] Automatically disable osg::Camera if node is culled
Hi Farshid, In scene graph osg::Camera have a bounding volume like all other nodes and are culled accordingly, there are some special rules though - if the Camera has an ReferenceFrame set to ABSOLUTE_RF then it's bounding volume is ignored and it's not culled. If you fit this case, or if the bounding volume of the Camera is larger than you need for your texture then a cull callback attached to a node above the Camera is probably something to use, this could then keep a bounding sphere to do the cull against the view frustum and make the decision about whether to cull the subgraph or not. Such a cull callback could be used in more circumstances than with just a camera. Robert.

Re: [osg-users] reuse of clipping planes?
Hi Jason, The number of clip planes supported by OpenGL is typically limited to 6, so for a single subgraph this is the hard limit your can't work around without doing your own shaders. The advantage your own custom clip plan class has is that it'd allow you to decorate multiple subgraphs each with it's own setting for the 6 clip planes, this overcomes the limitation the OSG adds by restricting you to 6 clip planes per RenderStage. Robert. On Thu, Jun 17, 2010 at 3:44 AM, Jason Jerald ja...@digitalartforms.com wrote: Ok, I created my own subclass from osg::ClipPlane and override apply(). I confirmed that the code is actually entering my new apply() method and successfully set the clipping planes with the correct transforms. However, it seems I am still limited to 6 clipping planes. I do not see how pushing/popping the modelview matrix and setting a new modelview matrix gets around the 6 clip plane limit. The modelview matrix already includes what I need (including the local geometric transform), so how does setting the matrix myself help? I must be missing something or perhaps I misunderstood your suggestion. The only thing I did was override ClipPlane::apply(State). I am not clear in your suggestion if you are saying this is the only thing that is needed or if I also need to set up a RenderBin (or a new RenderStage?) for each set of 6 clipping planes. Or perhaps I need to call apply() in a different way than how osg is already doing it? Or is there something else I am missing? Thanks!

Hi Jason, RenderBin's don't have any positional state setup so you can't use them directly to enable more clipping planes. Only RenderStage's set up the positional state. The FlightGear's workaround isn't a general purpose approach so isn't appropriate for the core OSG, so there hasn't been any changes merged for this in any OSG version. You can create you own equivilant by subclassing from osg::ClipPlane and overriding the apply() then setting the modelview matrix you want and applying the clipplanes and then restoring it afterwards before the end of the apply().

Hi Jason, Clip planes are an example of positional state, other examples are lights and eye linear texgen. All positional state requires a specific modelview matrix to be bound to them to position them correctly in space, so unlike other OpenGL/OSG state you can't just push/pop and state sort their state and expect to get the correct results. This difference is handled by the OSG by binding the positional state together with a modelview matrix found when encountering the ClipNode/TexGenNode/LightSource nodes, and these positional state are then applied once at the start of each RenderStage. Applying the state just once for whole RenderStage does enable us to position the state uniquely but unfortauntely also means that the positional state can only be in one place for the whole stage - you can't nest it. You can emulate having multiple sets of Clip planes/texgen/lights by having multiple stages, or do what is currently done in FlightGear, to use a custom StateAttribute that does the binding to the required modelview matrix in the CustomAttribute::apply() method taking care to push back the current modelview matrix to prevent the rest of the scene being affected.

[osg-users] QT and Horizontal Split Stereo
Hello all, I have a bit of a tricky problem which I hope some of you can assist with. I've recently moved our stereo graphics development over to QT and found this to work very well when we're using our quad buffered active stereo screens. However, I hit a rather perplexing snag when I was asked to get the same applications working with a passive stereo setup that uses a horizontal split stereo over two projectors. The problem is that in order for it to display correctly with horizontal split I would need to duplicate the QT interface on both screens and then obviously have the OSG widget display the left and right eye on their respective screens. This sounds like a bit of a mess to me and would require big changes in our QT framework. My thinking is that dual-projector passive stereo setups that use a horizontal or vertical split format are fairly common so someone must have got them working with a windowing interface before. So, if anybody has any pointers on a smart way to proceed I would be very grateful to hear them because at the moment I'm rather stuck :) Cheers, Kim. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Brad,
I had this problem when I developing the new serializer support in

Re: [osg-users] VPBMaster failing - build_master.source not loaded correctly.
Hi Robert,
I just did a clean (release) build of both OSG and VPB and re-ran my test, with
the same result. The revision of the osg source I used is: 11618 (12:49:45 AM,
Thursday, 17 June 2010) and for VPB it is: 1010 (11:23:36 PM, Thursday, 10 June
2010).
I added in some debug code to print out the number of color layers before
saving the .source file, and after loading it. Before save the terrain tile has
one color layer but after it is reloaded it has none.
I have had a quick shot at debugging it but I am having trouble getting my head
around how the new serializes work.
The simple test to reproduce the error is to run a command like:
vpbmaster --bluemarble-west -t aRandomPNG.png -o ./out/test.ive
Any tips on where to look or how to debug the issue would be great.
Cheers,
Brad

Hi Brad,
I had this problem when I developing the new serializer support in
VPB, but this has been addressed with fixes to the OSG that I checked
in last. The .source file looks OK so hopefully an update to OSG and
VPB and a rebuild will fix this problem.

Ok, I think I am getting close to the source of the issue, so hopefully
somebody may have some ideas.
The problem is occuring because the TerrainTile being loaded from
build_master.source has no color layers and no elevation layer. A manual
inspection of the file shows it does have a color layer so it looks like the
.source file is not being loaded correctly. Next step is to look into the
loading of the file.

Re: [osg-users] VPBMaster failing - build_master.source not loaded correctly.
Hi Brad,
I just run the test along the lines of yours:
vpbmaster --bluemarble-west -t
../BlueMarble/land_shallow_topo_west.tif -o out/test.ive
And it run to completion without any problems. The generated
build_master.source is included below, and looks pretty similar to
yours.
Could you try doing:
osgdem -s build_master.source --so test.source
This will load and then re-save the terrain description, the above
test results in test.source that is identical to build_master.source.
My guess is that on your system it won't be.
What OS/compilers are you using? I'm using Kubuntu 9.04 and gcc 4.3.3.
Robert.

HI Donlin, 2010/6/17 xyc508 xyc...@163.com: The Mobile here mean Windows Mobile or Win CE on Pocket PCPocket PC Phone device,can osg run on it ? what package it need? There is big difference between just say Mobile and Win CE, the more specific you are the better replies you'll get, we aren't mind readers. I believe one OSG users has attempt to compile the OSG on WinCE. I haven't received any patches yet, so I presume it either mostly works or that they haven't got round to posting them yet. There are no packages you just use for WinCE development - like the other OSG user who's looked at WinCE you'll need to compile the OSG from source using the new OpenGLES target (in OSG svn/trunk) and tackle what ever issues you come across in the port. I have no expertise on Windows let alone WinCE so I'll have to defer to members of the community for support for both, beyond saying it should be possible using the new OpenGLES target I can't give further guidance.

Hi,
Just ran the command. You are correct, the files are not the same, all the
layers have been stripped out. I am using WindowsXP, Visual Studio 2008.
I will do a fresh checkout and build when I get home tonight (if the kids allow
it : ) as I cant access an external SVN server from the work network. It seems
odd that the different platforms would result in this behavior so its worth a

Now that the simulation is set up we are ready for the simulation loop. This
loop will be slightly different than previous. After we've updated the scene
graph nodes and before we start the cull traversal we'll manually position the
camera that follows the tank. The other camera will present the default viewer
and interface. The matrix that is returned from our transform accumulator is
expressed in Y up terms. The camera that is used to position the camera is
expecting a matrix in Z up terms so we'll need to rotate the matrix. The code
to achieve this follows:
while( !viewer.done() )
{
// wait for all cull and draw threads to complete.
viewer.sync();
// update the scene by traversing it with the the update visitor which
will
// call all node update callbacks and animations.
viewer.update();
// Get a handle to the follower camera. Use camera class method to set
// the matrix to the world coordinate position of our tank follower.
// Rotate the matrix from Y up to Z up.
viewer.getCameraConfig()-
findCamera(tankFollowerCamera)-setViewByMatrix(
Producer::Matrix(tankFollowerWorldCoords-getMatrix().ptr() ) *
Producer::Matrix::rotate( -M_PI/2.0, 1, 0, 0 ) );
// fire off the cull and draw traversals of the scene.
viewer.frame();
}
// wait for all cull and draw threads to complete before exit.
viewer.sync();
return 0;

There isn't an equivalent, you just set up the slave Camera's directly on the View. Loosely you can view a Producer::CameraGroup as a osgViewer::View, and osgProducer::Viewer is equivalent to osgViewer::Viewer. FYI, you can load Producer .cfg files directly in osgviewer by using the -c cameraconfig.cfg, you can also load the configuration directly on the View. As JS suggests it would be worth learning what the Producer based code does and then separate learning how osgViewer::Viewer relates to cameras by looking at the examples. osgViewer::Viewer is pretty similar to osgProducer::Viewer, just a little more flexible and less of everything and the kitchen sink design - it's more pared down.

Re: [osg-users] Read texels from texture in GPU memory
Hi again, I appologize in advance for asking stupid questions;) By changing the line cam-setRenderOrder(osg::Camera::PRE_RENDER); to cam-setRenderOrder(osg::Camera::POST_RENDER); everything works as expected (src in my previous post). I have the following questions: 1: Is this correct behaviour? Does a camera have to be POST_RENDER for buffer read operations to take place in the final draw callback without errors. I was getting the correct results before, eventhough an error was thrown... 2: Is there any way I can get the value (a texel from a GPU resident texture) in the update traversal and in the same frame as I request it? The way I do it now I am always one frame behind, since the value is requested in the update traversal and fetched in the draw traversal. Thanks!

Hi Brad. We have only been using VPB 0.9.10 with OSG 2.8.3 for a little while, but we found using GDAL 1.6 worked, but 1.7 did not.

Another caveat, we're still using VS2005, but we're hoping to upgrade soon! :) Anyway, I thought you might be interested in the runtime problem, and how we worked around it, in case you run into similar problems.

[osg-users] Best way to get transformation animations from 3dsmax into osgAnimation?
Hi list, I've got models which are modeled in 3dsmax and are exported with OSGExp to .ive or .osg. I have (transformation) animations in 3dsmax (8 or 9) which are then exported to AnimationPathCallbacks. When I load these in osg they are animating nicely. However, I would like to have detailed control over the animation playback and I have been struggling with the AnimationPathCallback, and could not make it work properly. Also, I would like to use the more advanced osgAnimation (I like it a lot so far). Now I would like to use osgAnimation instead of the AnimationPathCallback. I have been trying the fbx format but I get very different results with the same scene (OSGExp compared to fbx exporter in 3dsmax 8/9) so currently I would like to take one step at the time, and prefer to use OSGExp and still convert to osgAnimation animations. Does anyone have a working strategy how to accomplish this? E.g. is there a straight forward way to convert AnimationPathCallbacks into osgAnimation?

I am off for a short break this morning but I will get back onto it Tuesday next week when I am back.

Hi Brad, The output all looks fine, the serializers for osgTerrain do seem to be loading, but for some reason are failing. Could you try a release build to see if that produces any different results. I'm clutching at straws though, I believe the code in question is identical for both platforms and should work fine. Do you have any unix systems you could try a test build and run on? Robert.

Hi, Does the osgdem -s .. --so .. test produce a source file with the vpb::DatabaseBuilder entry in it? Yes. The DatabaseBuilder is there but there are no color layers. For the results that follow, all the binaries I have just built from a fresh checkout are in D:\osg\vpb-bin\bin. Before the run, in the shell, I set the PATH to only include that directory. It appears that that is where the DLLs are getting loaded from. However, it isn't finding osgterrainrd.dll or orgrd.dll. All my OSG DLLs have been created using the naming convention: osg66-osgrd.dll, osg66-osgTerrainrd.dll etc (I built release with debug binaries). Not sure if this has anything to do with it. I ran this with notify set to debug: osgdem -s build_master.source --so test.source out.txt The results are attached, out.txt is the console output. Thanks for your help.

Unfortunately I still have the same problem. Looks like I will need to fix the problem that occurring with my OS/compiler. Can you suggest any areas that I should look at first? I am guessing the issue will be in osgTerrain serializer plug-in. Does the osgdem -s .. --so .. test produce a source file with the vpb::DatabaseBuilder entry in it? Could you post the result, it might give a small hint to what might be going wrong. Is there any chance you are linking to slighty older version of the OSG/plugins are runtime? Could you set OSG_NOTIFY_LEVEL to DEBUG and then re-run the test: osgdem -s build_master.source --so test.source And post the results, there is chance it might give a clue to what is going amiss.

Re: [osg-users] Visual Studio 2010 and VPB
Hi, I am interested as I would like to move to the latest gdal version. I have reverted back to 1.6 for now for different reasons but would like to upgrade. Please do share hw you worked around the runtime problems. Cheers, Brad -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of D.J. Caldwell Sent: Friday, 18 June 2010 1:26 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Visual Studio 2010 and VPB Hi Brad. We have only been using VPB 0.9.10 with OSG 2.8.3 for a little while, but we found using GDAL 1.6 worked, but 1.7 did not. I'm not sure what the exact problem was, but I think we had a runtime error (I know, you're experiencing linker problems) having to do with mapping the texture to the geometry. Another caveat, we're still using VS2005, but we're hoping to upgrade soon! :) Anyway, I thought you might be interested in the runtime problem, and how we worked around it, in case you run into similar problems. Good luck... D.J. On Wed, Jun 16, 2010 at 10:35 PM, Christiansen, Brad brad.christian...@thalesgroup.com.au wrote: Hi, Thanks for the suggestions. I have checked that both are built with the same options, including the 3rd part dependencies, and as far as I can tell, they all are. I did end up using the /FORCE:MULTIPLE option but I really don't like just ignoring the issue. For now I have moved back to VS 2008 as I have run out of time to get things working. Hopefully I will get a chance to look at it again soon as this was the final hurdle to having everything building correctly.
