Re: [osg-users] include conflict while compiling osg 2.9.11

This isn't something that is wrong with wither OSG or Qt, but the way that X11 headers use common names used methods, typedefs and classes polluting any attempt of C++ files to use these. The C++ files might be good citizens and use namespaces so they don't polute third part code, but they can't protect themselves from pollution from C headers included before them. If you are going to use headers that pollute in an uncontrolled way like the X11 ones then you are left having to included them after any of the other headers that would be polluted by them. I would add that with the latest version of the OSG we now have a osgQt library with it's own GraphicsWindowQt that simplifies the process of integating the OSG and Qt so that you no longer need to play with window handles, so no need to go explictly include X11, so the proplem you are seeing right now is something you shouldn't need to come across.

If you want to create and chain RenderStages then using an osg::Camera in the scene graph is often one of the best ways to do this, and use the Camera::setRenderOrder(..) to control the order. You can also use a custom cull traversal callback to create RenderStage/RenderBin and assign these to the rendering backend, but this does require a greater knowledge of the internals of the rendering backend.

Good morning everyone, I hope everyone of you had a nice and enjoyable weekend? Here in Germany it was brilliant weather, in addition, yesterday was mother's day so we had a very enjoyable time with the family - hope the same for you! :) Anyways - first off, thank you all very much for your answers. Torben, I did read into your code on Friday and, from a first glance at it, it seems like a possible solution for the problem. I think the perfect way to create that matrix would be by using a camera and creating the distortion pixel map by analysing the offset dynamically via the camera image. It's a quite complex way to do it, but the result should be quite good - however, if I can't find a student to write his bachelor thesis on that, I fear there won't be resources available to do it ;) Shayne, thank you very much - the links you offered perfectly describe the issues I'm dealing with. If I understand you right, I am already tweaking the frustum to calibrate the viewing area by using setProjectionMatrixAsFrustum(left, right, bottom, top, near, far); . The problem with this method is that by using each of those parameters I can only move an entire border of the projection area - so the entire left, right, bottom or top border of the frustum. This allows me to adjust the frustum such that it does fit into the projection screen; however, it does not help at all against the distortion in the image. To do so, I had to be able to move the corners of the frustum individually, and that's something I don't quite know how to do it. I'll read into the paper more deeply and will let you know if it could help me any further.

Re: [osg-users] Looking at OSGExp and maya2osg (3dsmax and Maya export plugins)
Hi Farshid, 1) Adding prefix/suffix to image filename. I believe this is the easiest method. The filename will be applied to the exported osg::Image object. For example, you can append _[normal] to all normal map images. I think this is a bit too intrusive. The artist should be able to name their images however they want... 2) Adding tags to the material name. Using the Material Editor in Max, you can set the name of a material to any arbitrary string. The name will be applied to the corresponding osg::StateSet and osg::Drawable object. I'm thinking of changing this so it is only applied to the osg::StateSet object. Using the previous example, you can append _[normal] to the material name to flag that it contains a normal map. That's a better idea I think. And then on load, when we have interpreted the file and determined we need to load the normal map, we can remove the suffix so that the real name is there again. 3) Modifying the object properties. I wouldn't recommend this technique for material related settings. We use it for node related settings. Right-click an object in the scene and select Object Properties. Select the User Defined tab and enter any mult-line string within the textbox. This gets exported as a description string of the corresponding osg::Node object. Do even materials have user defined object properties? If so, then I think this is the best option for all settings, as it can be arbitrary settings and arbitrary length. For example, the exporter might want to set a tag saying that the material needs a normal map, but also include the filename of the normal map texture and the amount of bump. Other types of effects might have other settings too. Including all that in the material name will get hard to parse, whereas with user defined properties, we could have one setting per line and it's easy to parse. I'll have a look at what I can do to do that. Thanks for the examples.

Re: [osg-users] Looking at OSGExp and maya2osg (3dsmax and Maya export plugins)
Hi Javier, I have to get deeper in this issue, but unfortunately I won't have much time for it. I'll let you know if I get to something. I've found out what the problem is: When the Phong class tries to generate a shader code block ( Phong::getCodeBlock() ), if the material was actually a Blinn, then it has no cosinePower plug, so it gives a runtime error there. For some reason when the plugin is compiled with optimization enabled, when printing that runtime error it crashes. I'll fix it correctly and send you the changes. I initially didn't want to duplicate the Phong class to make a Blinn class for so little difference between the two, but in retrospect it will be cleaner.

I'm working on a project in which I want to render side-by-side video with some
other stereo objects. And later reproduce this on a stereo TV.
I'm using a decklink card to capture and playback the final scene.
The problem I'm finding is that I cannot save the final scene in stereo mode in
my m_frameBuffer, I only get an output of a non-stereo configuration.
osg::ref_ptr osg::Camera _Camera = new osg::Camera();
Camera -attach(osg::Camera::COLOR_BUFFER, m_frameBuffer);
while( !viewer.done() )
{
viewer.frame();
sprintf(_str, image.png);
osgDB::writeImageFile(*m_frameBuffer, std::string(_str));
}
where should I define the osg::DisplaySettings-setStereo(true)
to my viewer or to my _Camera, both ?
I'm quite messed up, any ideas in what might I be doing wrong?
Thanks a lot in advance!

Re: [osg-users] large VBOs for multiple Drawables
Hi Fred, On Mon, May 9, 2011 at 3:42 PM, Fred Smith osgfo...@tevs.eu wrote: It means that there seems to be a cost in doing state changes with OSG. Indeed there is!! It's written to be lightweight, using pointer rater than content comparisons where possible, but you can't ever disappear CPU cycles completely. This work that the OSG does on state is to minimize the number of state changes sent to OpenGL, so while there is a higher CPU cost, the GPU cost is lower. GL state changes do not necessarily incur any cost - this is implementation specific anyway - whereas OSG state changes seem to always incur one, as even going through empty statesets does incur a cost. Some GL state changes are relatively lightweight, but since any GL call overhead itself is not cheap, avoid GL calls is worth the effort, and some GL state changes are hugely expensively. The OSG does state sorting and lazy state updating to make sure that the graphics is sent to the GPU as efficiently as it can. As for empty StateSets, the OSG during traversal doesn't know a StateSet is empty until it checks it contents, do so waste time of course, but there is nothing the OSG can do during traversal to avoid this. However, an empty StateSet is a indication of very poorly set up scene graph. Efficient scene graph don't have rendundent StateSet or Node's in the scene graph, the osgUtil::Optimizer contains are plarethora of visitors to help condition poorly balanced scene graphs, so if you do have a problem scene graph the Optimizer is a great tool to utilize as a pre-processing step. Performance problems that end users see are almost always caused by scene graphs that are poorly constructed for the purpose that have been created for, so if you see high update, cull and draw dispatch and draw GPU investigate the bottlenecks with a view to understanding what in your scene graph is introducing the large overheads. The skill of creating an optimal scene graph isn't a trivial one though, it's one of the core skills for real-time graphics experts to develop, a skill that takes many years to mature. I am still a learning, and don't really every expert to stop learning about this as technology continues to evolve at a break-neck speed.

Re: [osg-users] Looking at OSGExp and maya2osg (3dsmax and Maya export plugins)
Hi Javier,
In the end, the fact that the shader generation code in phong.cpp was
trying to access a plug that didn't exist for a blinn material wasn't
the cause of the crash (the code is well guarded so it just returns an
empty plug). Plus, that plug is never used anyways (the
gl_FrontMaterial.shininess is used, and that was set according to my
approximation in shader.cpp, so that should be fine). Still, I made the
Blinn class anyways so it's a starting point if we ever want to refine it.
What I did to remove the crash (at least until we can find the real
cause) is to disable optimization for the function where it crashes.
I also saw that one of the plugs was missing in phong.cpp, and even if
it's empty, for completeness I added it.
So find the modified files attached. They all go in src/GLSL, except the
CMakeLists.txt which goes into the root.
Thanks in advance,
J-S

Re: [osg-users] large VBOs for multiple Drawables
Hi Robert, The stateset performance issue, if ever encountered, can easily be worked around with a draw callback using applyAttribute/applyTextureAttribute prior to rendering every drawable. This is a very slim point where there might be room for improvement, and what you said perfectly makes sense to me.

[osg-users] How to know when paged scene is loaded
Hi, I would like to know if there is any way to get a callback or something when a paged scene is finished loading. My scene (terrain) is paged from disk and when i move my camera it will take some time to page in all the geometry and so on. What would be the best way to check when all geometry are finished loading ? I know there are some kind of queue system on what files to load when working with paged files. Could i for example check that, and when the queue is empty, i could assume that everything is loaded ? Or is there already some mechanism in osg for this ? If someone could point me in the right direction, i would be very happy! :) Thank you!

Re: [osg-users] Manual perspective distortion?
Alexander, By moving the corners of the frustum, are you wanting to tweak the frustum corners so that they have different depths (i.e. tilt the near plane so that it is no longer orthogonal to the eye)? I don't think OGL (and hence OSG) will allow you to do this directly. There is a munge that may allow you to effectively specify an oblique near clipping plane to give you the effect you're looking for. Check out the link http://www.terathon.com/gdc07_lengyel.pdf. Pay particular attention to the last part of the presentation. If you want to do distortion correction, you can resort to another technique other than just using the projection matrix. One way to do this is to use a two-pass solution whereby you render to texture and then distort the texture coordinates at small increments before rendering to an on-screen buffer. I think the first link I sent you last week talks about this. There are other ways to do the distortion correction as well such as shaders, etc. -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Alexander Dieterle Sent: Monday, May 09, 2011 3:18 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Manual perspective distortion? Good morning everyone, I hope everyone of you had a nice and enjoyable weekend? Here in Germany it was brilliant weather, in addition, yesterday was mother's day so we had a very enjoyable time with the family - hope the same for you! :) Anyways - first off, thank you all very much for your answers. Torben, I did read into your code on Friday and, from a first glance at it, it seems like a possible solution for the problem. I think the perfect way to create that matrix would be by using a camera and creating the distortion pixel map by analysing the offset dynamically via the camera image. It's a quite complex way to do it, but the result should be quite good - however, if I can't find a student to write his bachelor thesis on that, I fear there won't be resources available to do it ;) Shayne, thank you very much - the links you offered perfectly describe the issues I'm dealing with. If I understand you right, I am already tweaking the frustum to calibrate the viewing area by using setProjectionMatrixAsFrustum(left, right, bottom, top, near, far); . The problem with this method is that by using each of those parameters I can only move an entire border of the projection area - so the entire left, right, bottom or top border of the frustum. This allows me to adjust the frustum such that it does fit into the projection screen; however, it does not help at all against the distortion in the image. To do so, I had to be able to move the corners of the frustum individually, and that's something I don't quite know how to do it. I'll read into the paper more deeply and will let you know if it could help me any further. Have a great start in the new week! -Alex -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39189#39189 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Is osg 2.9.9 recommended for Qt integration
Hi, I have been playing around with the osgviewerQt example that came with osg 2.8.2. Then I looked at the examples that are in the source for 2.9.9 and there seem to be a lot more. Is it recommended that I upgrade or have other users got successful and acceptable results with 2.8.2 (or anything lower than 2.9.9) Thanks Sincerely, Sanat -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=39224#39224 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [3rdparty] OSG C#
If you're using standard Visual Studio, using C++/CLI interop to write managed (ref) classes that interop with OSG and are callable from C# is going to be the most powerful approach. In order to render into a Windows Forms control, you create an empty control, get the native HWND and provide it to osgViewer. If you are using Visual Studio Express or Mono, or hate C++, you need to deal with osgWrappers and P/Invoke and unsafe memory management, which is going to be considerably more brittle.

}
such as :osg::geometry::useservertexbufferobject(true). and then specify the

Re: [osg-users] include conflict while compiling osg 2.9.11
Hi Lv, It is a known issue of the osgviewerQt example under Linux. AFAIK, OSG's multithreading mechanism could well with QtOpenGL under Windows, but the make current operation is confused when using QGLWidget as the low-level graphics context. With Qt 4.7 and Ubuntu 10.10, the example seems to work with warnings, but still not responsible. Maybe somebody could help debug into the Qt source code to find the problem later.

Hi, FYI, Paul Martz's OpenSceneGraph Quick Start Guide is preferred for beginners in my opinion. And Qian Xuelei and I wrote a book OpenSceneGraph Beginners Guide in the end of last year, which is published by the Packt Publishing. Do some search in the osg-users archives could be of a lot help, too. As I guess you are from China, I'll also suggest the osgChina forum (bbs.osgchina.org), and some Chinese materials, like The Longest Frame (in Chinese, 最长的一帧) written by me, and two OSG publications published by the Tsinghua University Press.
