Re: [osg-users] trouble in MSFBO
Hi, Paul and Michael
Frist Thank you for your suggestion.
I use the your method, and output show correctly in normal rendering, but when
I use my deferred render, it has aliasing, I use a TextureRectangle as
normal_sampler, below is my fragment shader:
#version 120
uniform sampler2D normal_sampler;
varying vec3 normal;
centroid varying vec4 texcood;//texcoord is gl_Position from vertex
shader
void main()
{
//vec3 snormal = 2.0*texture2DRect(normal_sampler, gl_FragCoord.st).xyz -
vec3(1.0, 1.0, 1.0);
vec2 tex_coord = 0.5*texcood.st / texcood.w + 0.5;
vec3 snormal = 2.0*texture2D(normal_sampler, tex_coord).xyz - vec3(1.0, 1.0,
1.0);
float diffuse = dot(normalize(snormal), -1.0*gl_LightSource[0].spotDirection);
gl_FragColor = vec4(diffuse, 0.0, 0.0, 1.0);
}
I also change the filter of normal sampler to linear, it also makes the same
result.
you can also see the screen output in attachment:
Thank you!
Cheers,
Kai

Re: [osg-users] [osgOcean] Error with osgOcean-VBO Example!
Oceansurface wasn't initialised, I've fixed and checked this in to the branch. Only additional hardware requirement is VBO support which I gather is pretty standard. If you find that you have problems with this you can disable the use of VBOs in the FFTOceanSurfaceVBO constructor and recompile. It should still work. Regards, Kim.

[osg-users] osgText - fragment shader - font texture
Hi,
I try to use shaders with osgText to make some effects with text. But how I can
set up uniform variable with font texture to process it in fragment shader? Or
may be I should do something another to have result?
Primitive fragment shader:
Code:
uniform sampler2D bitmap;
varying vec2 texelCoord;
void main( void )
{
gl_FragColor = vec4( texture2D( bitmap, texelCoord ) );
}
Code which sets the variable:
Code:
//...
osg::Uniform* bitmap = new osg::Uniform(bitmap, osg::Uniform::SAMPLER_2D);
bitmap-set(??);
text-getOrCreateStateSet()-addUniform(bitmap);
//...
Thank you!

Re: [osg-users] GraphicsContext on Multiple Graphics cards?
HI Akilan, The OSG by default will open up windows right across all the attached screens with the assumption that are all working side be side like a powerwall. However, it won't necessarily know the screen layout so you well may need to adjust the set up the slave Camera view and projection matrix offsets to get the exactly the results you are looking, and set the screen number assigned to each graphics card. The osgcamera example illustrate hows to set up the Camera's and associated GraphicsContexts for the viewer by using a combination of GraphicsContext::Traits to supply details of the actual display you want to take, and the Camera for assigning the GraphicsContext created and setting up the view and projection matrix details.

Re: [osg-users] light multi-parenting
Thanks Robert, to close the thread, I am putting more info based what you have written and my experiments: - LightSource with Light attached - can be far down in the scene graph while it shines on whole scene. It uses PositionalStateContainer of RenderState to store light position. Advantages: - huge benefit is that the light shines on whole scene. That is how we expect the things happens in reality.

Advantages: - OpenGL IDs can be shared, provided that up to 8 lights with unique ID shines at any moment - multiple references / multi-parenting (with different transformations) works correctly and lights are instanced correctly on multiple positions Limitations: - To make the light shine on the whole scene or specified part of the scene is little bit troublesome in some cases. Especially, if the light position is expected to be animated by some transformation down in the scene graph. - there are still some issues in OSG implementation on multiple light references, but it can be (hopefully) easily fixed, if needed To express my opinion after the understanding of lights: Lights are very well designed.

Re: [osg-users] light multi-parenting
Hi John, Actually LightSource doesn't illuminate by itself, it just provides the settings for glLight and position it correctly and uniquely in space. In OpenGL you don't actually get illumination even when you set glLight, you only get illumination once you enable GL_LIGHTING and GL_LIGHTi. In the OSG case the subgraphs that will illuminated are the parts that you've enabled GL_LIGHTING and the appropriate GL_LIGHTi for, osg::Light and osg::LightSource don't have any effect apart from the actual values used by the lighting model. As for limitation osg::Light/LightSource/OpenGL lighting all work with the same limitations - that is there is only ever guaranteed to be 8 fixed function pipeline light supported. If you want to use more than 8 then you'll need to use shaders, or localize the lights to difference subgraphs have different lights assigned for them. The fact you need to position lights as well means that one has to apply the appropriate modelview matrix for each of these lights before application, which complicated the implementation. The only way to tackle this right now with the OSG is to break the scene up into separate subgraphs that each target their own RenderStage. This is possible, but awkward at present. The same issues apply to all positional state - eye linear texgen, clip planes and lights. Robert.

[osg-users] Erros with ProxyNode
Hi, there seems to be an error using proxyNodes. If you setup a proxyNode using multiple filenames, not all files may get paged in correctly. This is related to the sequence the databasepager loads nodes, which may vary if you load nodes using curl. There is no association between the filename and the node which gets paged in, so the proxyNode, request may request nodes twice. Possible solution: Let ProxyNode::traverse only request one Node at a time. If the file is not found however, the follow up filenames will never be requested.

Re: [osg-users] Erros with ProxyNode
Hi Richard, Interesting bug... fixing it is likely to be a bit awkward given the currently implementation of ProxyNode/DatabasePager, doing one file at a time won't even address all the potential issues as the ordering can sit get out of sync if early children fail to load but later children succeed. Adding support into DatabasePager to allow it to set specific children would require osg::Group to support having null children, something which has quite a few potential pitfalls. My first thought for a solution would be to change ProxyNode so that is only has one filename, rather than multiple ones as it has now. This would avoid any issues about which files are loaded and keep the filename list in sync with the children. This is an API change though, but I can't see a better option right now. Thoughts?

If you setup a proxyNode using multiple filenames, not all files may get paged in correctly. This is related to the sequence the databasepager loads nodes, which may vary if you load nodes using curl. There is no association between the filename and the node which gets paged in, so the proxyNode, request may request nodes twice. Possible solution: Let ProxyNode::traverse only request one Node at a time. If the file is not found however, the follow up filenames will never be requested.

I'm not 100% clear on what you mean in this sentence, but I can confirm that the ScreenIdentifier is what you need to set, with the screen number referring to graphics context/card. It is possible to configure OS's/drivers/hardware to have a single graphics context across two or more outputs from a single graphics card, or to have a single graphics context across each output - in which case the screen number you use will refer to unit you set up. The OSG doesn't have any control over this setup, you'll need to look at your driver control panels/configuration for this. If you just set up one display, one context per card then things a little more straight forward in screen number relationship to the the card.

Re: [osg-users] REGISTER_OBJECT_WRAPPER problems
Hi Butler,
To make use of serializers, your class requires a namespace, for
example, NS::Foo. And then override className() and libraryName(), the
META_Object macro would help a lot.
To use ADD_STRING_SERIALIZER. Your should have a pair of suitable functions:
void setNote(const std::string);
const std::string getNote() const;
And ADD_INT_SERIALIZER requires a little different approach:
void setNumber(int);
int getNumber() const;
Basic data types like bool, int and float, doesn't need a prefix const here.

Re: [osg-users] light multi-parenting
As for limitation osg::Light/LightSource/OpenGL lighting all work with the same limitations - that is there is only ever guaranteed to be 8 fixed function pipeline light supported. If you want to use more than 8 then you'll need to use shaders, or localize the lights to difference subgraphs have different lights assigned for them. The fact you need to position lights as well means that one has to apply the appropriate modelview matrix for each of these lights before application, which complicated the implementation. The only way to tackle this right now with the OSG is to break the scene up into separate subgraphs that each target their own RenderStage. This is possible, but awkward at present. Thanks.

Re: [osg-users] Stereoscopic Problems
Hi Ronny,
It looks like the stencil buffer is not being properly setup. Are you sure
that your application allocates a stencil buffer when creating the OpenGL
context?
Cheers,
Farshid

Hi,
When activating horizontal/vertical interlace or checkerboard, I get the
following result: img229.imageshack.us/img229/9520/stereofy.png
I tried my application with horizontal interlace enabled on my thinkpad
laptop where I got interlace working as expected.
Thus I assumed this might be caused by the display driver; I installed
196.21_desktop_win7_winvista_64bit_international_whql and the beta driver
197.13_desktop_win7_winvista_64bit_international, none of which solved the
problem.
I currently have two GeForce GTX260 setup in non-SLI using three monitors.
Any suggestions?
I also tried to change the stereoscopic mode after initializing the camera
and viewer (the camera variable is set as a public member of the mOSG
class):
Code:
void CMyView::SetStereoscopicMode(DisplaySettings::StereoMode mode) {
DisplaySettings *stereoSettings = new DisplaySettings();
if (mode == NULL) stereoSettings-setStereo(false);
else {
stereoSettings-setStereo(true);
stereoSettings-setStereoMode(mode);
}
mOSG-camera-setDisplaySettings(stereoSettings); // Works fine
mOSG-getViewer()-getCamera()-setDisplaySettings(stereoSettings); //
Does not work
}
Is there a way to make -getViewer()-getCamera() work and leave the camera
variable protected/private?
Thank you!
Best Regards
Ronny Hatteland

Re: [osg-users] Stereoscopic Problems
Thanks for the response Farshid, That might be the case. How/Where can I check if the stencil buffer is set correctly? Btw I just tried on another computer with Nvidia graphics (8800GTX) using OSG 2.8.3-rc1 (I used 2.8.2 previously), also being unable to draw the patterns. I imagine this is a bug regarding Nvidia graphics since it is working on my computer with an Intel mobile graphics display driver.

Re: [osg-users] bluring model edges
Guy and Julia I still can not get this code snippet to work. Would you please tell me what I might be missing? I've provided my sample code and have commented out the code snippet below because I could never see any changes. Guy wrote: Julia, I never tried it but you should enable GL_POLYGON_SMOOTH, and enable alpha blending for the object you want to 'blur'. For example: osg::StateSet * stateset = geode-getOrCreateStateSet(); stateset-setMode(GL_POLYGON_SMOOTH, osg::StateAttribute::ON); osg::BlendFunc *fn = new osg::BlendFunc(); fn-setFunction(osg::BlendFunc::SRC_ALPHA, osg::BlendFunc::ONE_MINUS_SRC_ALPHA); stateset-setAttributeAndModes(fn, osg::StateAttribute::ON); stateset-setMode(GL_BLEND, osg::StateAttribute::ON); stateset-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); Good luck, Guy. Hi, Is it possible to blur the edges of a model in OSG with whatever is behind? Currently the edges of the models in my scene are too sharp and would look better if there was a translucent overlap at the edges. Is this possible to achieve in OSG, or is this kind of functionality more relevant to OpenGL?

[osg-users] ffmpeg plays correct, but slows down after loop
Hi, Has anyone experienced the slowing down of video (approx half speed) after it loops? ie, the movie plays at regular speed the first iteration, but once it loops, the speed is slow. This is an FFMPEG plugin issue. I can reproduce this with the osgmovie example (unmodified) in OSG 2.9.7 The plugin reports the following for the video: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'OceanBeach1_FullShortShort_H264.mov': Duration: 00:02:24.23, start: 0.00, bitrate: 15663 kb/s Stream #0.0(eng): Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Stream #0.1(eng): Video: h264, yuv420p, 1024x1024, 30 tbr, 600 tbn, 1200 tbc One last question: What is the optimal format for ffmpeg + osg?

Re: [osg-users] Stereoscopic Problems
I got the osgScreenCapture example working with horizontal interlace, so probably there must be something wrong with how I have implemented it in my project. I will look into it, maybe I'll sort out my mistake by going scrupulously through the example ;) Cheers, Ronny -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26106#26106 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] custom WindowProc for handling multitouch events
Hi, I am wondering how I may incorporate custom windows messages into an osg-based application that creates several windows using GraphicsContext::createGraphicsContext(). What I'm trying to do is, to implement multitouch capabilities, therefore I have to handle the native WM_TOUCH messages in the window procedure. Since I noticed that the WindowProc function in GraphicsWindowWin32.cpp just calls the handleNativeWindowingEvent method of the according GraphicsContext instance, so my first idea was to create a class that derives from GraphicsWindowWin32 and overwrites this method. But there does not seem to be a possibility to trick the Win32WindowingSystem to use this class instead. Of course, I could take care about class registration and window creation on my own, but I'd rather use the provided convenience functions. I also could do a hack in osg itself, as suggested in this thread (http://forum.openscenegraph.org/viewtopic.php?t=2271highlight=), but I also would like to avoid that. Another way would be to install a windows message hook. I would prefer to to this as sober as possible to avoid problems later on. Are there any best practices for handling windows messages in osg? Are you already providing an interface for that, which I was not able to find? Thanks!

Re: [osg-users] Error with pixel puffer in trunk
HI all, I have now resolved the issue. I am not sure exactly what the PBO issue was but I suspect I failed properly clean my build. The artefacts were present as it seems that the default behaviour of PRE_RENDER cameras has changed with respect to their clear masks. To fix my issue all I had to do was explicitly tell each of my PRE_RENDER cameras to clear the depth and colour buffers.

Since the update, in my application, which is based on the MFC example (though my native window handle comes from Java) I am getting some very 'interesting' visual artefacts and the following error (about 10 times on start-up, then every time I resize the window or do the RTT): no PixelBufferObject , pbo= As far as I am aware I am never even requesting a PBO. The artefacts I am seeing are related to two (extra) cameras I have in the scene. Both cameras are pre-render, one renders a star field with a very large far plane value (the depth buffer is then cleared by the main camera) and the second camera does a RTT which is projected onto the globe. I am seeing the objects rendered by the cameras but they do not seem to be doing the correct clear operations. I have not modified any of my code, just simply re-built it. I have attached a screen shot to demonstrate the artefacts. I have no idea where to look to track down the issue. Any suggestions would be greatly appreciated. I am setting up the graphics context exactly as I was before: RECT rect; // Get the current window size ::GetWindowRect(hwnd, rect); // Init the GraphicsContext Traits osg::ref_ptrosg::GraphicsContext::Traits traits = new osg::GraphicsContext::Traits; // Init the Windata Variable that holds the handle for the Window to display OSG in. osg::ref_ptrosg::Referenced windata = new osgViewer::GraphicsWindowWin32::WindowData(hwnd, true); // Setup the traits parameters traits-x = 0; traits-y = 0; traits-width = rect.right - rect.left; traits-height = rect.bottom - rect.top; traits-windowDecoration = false; traits-doubleBuffer = true; traits-sharedContext = 0; traits-setInheritedWindowPixelFormat = true; traits-inheritedWindowData = windata; osg::GraphicsContext* gc = osg::GraphicsContext::createGraphicsContext(traits.get()); m_viewer-getCamera()-setGraphicsContext(gc); m_viewer-setThreadingModel(osgViewer::ViewerBase::SingleThreaded); Cheers, Brad DISCLAIMER:--- This e-mail transmission and any documents, files and previous e-mail messages attached to it are private and confidential.
