Re: [osg-users] Change uniform array size
Hi Peterakos, How you would tackle the problem depends upon what your need are for changing the number of uniforms. In terms of OpenGL objects it's generally best to used fixed size objects so that you don't have to reallocate them. To change the size used by the shader one would simply pass in second uniform to control how man samples are used. Robert. On 12 November 2012 19:36, Peterakos hay...@gmail.com wrote: Hello. Is there any way to change uniform array size ? What i do now is: const int num_of_samples = 64; uniform vec3 sample_kernel[num_of_samples]; Can i have num_of_samples as uniform ? If not, is it a good idea to have sample_kernel's size as 512 or 1024 and iterate only num_of_samples ? thank you. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] how to use several texture one time?
H Shawl,
The OSG supports multi-texturing, simply assign each texture to its own
texture unit. See the osgmultitexture example and osggeometry examples to
see how to assign multiple textures and set up text coords.

the problem is that just one texture unit works .
in case :
for (unsigned int gr = 0; gr header.ngr; gr++){ unit 0
works
for (unsigned int gr = 1; gr 2; gr++){
unit 1 works
then , how can i show the whole mesh with texture?

Hi Li? Zhenpeng? Could you sign with the name you wished to be address as. Thanks. There looks to be two separate classes of problems - missing dependences (peg and freetype) and the X11 error. To solve the dependencies issues you'll need to pull in the dev packages, a list of the most common dependencies is listed on the page below (you may need to adjust a little for variations between versions of Ubunutu): http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/Debian-Dependencies Once you have the dependencies you'll need to rebuild the OSG, to force it to check again for the dependencies remove the OpenSceneGraph/CmakeCache.txt and then re-run the ./configure. The X11 error is something I can't help with. I've used similar AMD hardware before and haven't had problems under Kubuntu. Robert.

[osg-users] Custom cursors and OSG used from .NET
Hello!
I am creating an osg scene, which is rendered to a .NET picture box on a
windows forms scene.
Code:
void startInFormWinCpp(int wh){ //wh is a window handle
HWND hwnd = (HWND)wh;
baseViewer = new osgViewer::Viewer();
osg::ref_ptrosg::GraphicsContext::Traits traits = new
osg::GraphicsContext::Traits();
traits-inheritedWindowData = new osgViewer::GraphicsWindowWin32::WindowData(
hwnd );
traits-setInheritedWindowPixelFormat = true;
traits-supportsResize = true;
RECT rect;
::GetWindowRect( hwnd, rect );
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;
osg::ref_ptrosg::GraphicsContext graphicsContext =
osg::GraphicsContext::createGraphicsContext( traits.get() );
baseViewer-getCamera()-setGraphicsContext( graphicsContext.get() );
baseViewer-getCamera()-setViewport( new osg::Viewport( 0, 0, traits-width,
traits-height ) );
baseViewer-getCamera()-setProjectionMatrixAsPerspective(30.0f,
static_castdouble(traits-width)/static_castdouble(traits-height), 1.0f,
1.0f);
baseViewer-setCameraManipulator(new osgGA::TrackballManipulator());
camera=baseViewer-getCamera();
camera-setClearColor(osg::Vec4(0.7f, 0.7f, 0.7f, 1.0f));
osg::ref_ptrosg::Group rootViewGroup= new osg::Group();
rootViewGroup-addChild(rootGroup);
baseViewer-setSceneData( rootViewGroup.get() );
_beginthread(renderStatic, 0, (void*)this);
}
I want to use some custom cursors depending from what am I doing. But on these
objects, there are no functions to set the cursor (only if I would get a
osgViewer::GraphicsWindowWin32). So I tried to change the cursor in .NET, this
works only sometimes (on mouseDown I change the cursor - this is OK, on mouse
up I change it again, but the default arrow is shown istead of my custom
cursor).
I also tried to set traits-useCursor = false; but then the cursor
disappeared (after mouseUp).
So the question is - how can I disable the overriding of the cursor in osg? OR
how can I use a custom cursor - in OSG, when I use a HWND from .NET to render
the scene? Has anyone experience with this?
Thank you for your answers!
Cheers,
Peter[/code]

Re: [osg-users] failed to create osg environment on ubuntu11.10
Hi Li, Just a long shot... have you tried to set LD_PRELOAD to your libGL.so library. I have had similiar problems in the past with the old ATI drivers as well as the Mesa drivers. Something like export LD_PRELOAD=/usr/lib/libGL.so could do the trick. Anyway check your environment variables with the command 'env' to see if there exist any variable pointing to your libGL drivers.

Hi Jan, Yes, preloading an incorrect version of the library will only give you more problems, that's the reason why I said to check the environmet variables. BUT in older versions of Ubuntu and with Mesa drivers there was a bug with the DRI drivers not linking to the libGL library see [1] and [2]. I have experienced the same error on ATI cards. Anyway I agree that it seems like a bad driver installation. Cheers.

Re: [osg-users] failed to create osg environment on ubuntu11.10
Hi Jordi, That's great. I believe you find the issue I encountered. Following is my check result. *env | grep -in libgl* 14:LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri:/usr/lib32/fglrx/dri That means no variable pointing to my libGL drivers. I checked /usr/lib directory and there is no libGL.so file. Is your OS is ubuntu too? Is ligGL.so is a link file or a real lib file? Here is my search command: sudo apt-cache search libgl. It is hard to select correct library from more than twenty libraries to install. BTW, libGL is an runtime lib? Should I re-configure-compile-install osg after I set LD_PRELOAD?

Hi Li, Have you compiled OSG in 32 or 64 bit? Check if in /usr/lib/fglrx/dri or /usr/lib32/fglrx/dri do exists libGL depending on your target architecture. As Jan said a the output of glxinfo could give some light. libGL is supposed to be installed/replaced with your drivers. Cheers. 2012/11/13 robotspace.biz robotspace@gmail.com Hi Jordi, That's great.

Re: [osg-users] Review of osgQt changes.
Martin, all. That is indeed great news, but we would need to maintain Qt4 compatibility for a number of years ahead. It also confirms the idea of a base-class in osgQt::GraphicsWindowQt::WindowData that would be inherited by various implemtations, where one would be Qt4, one Qt5 and one with something else. As there has been few comments on my last e-mail, I will go ahead and make an updated proposal. I'll keep you posted. Cheers, Kristofer -- Kristofer Tingdahl, Ph. D.

Is ligGL.so is a link file or a real lib file? There should be actually both. The versioned libGL.so.x.x and non-versioned symlinks libGL.so pointing to the versioned one.

However, do make sure that you don't have a messed up installation, linking OSG to e.g. the libGL from Mesa (software driver). That wouldn't work right. Please make sure to follow these instructions and install the driver properly: https://help.ubuntu.com/community/BinaryDriverHowto/ATI The part 2. Installation via the Ubuntu repositories should be sufficient.

[osg-users] osg::LineStipple - dashed lines unexpected behaviour
Hi, I am using osg to display just a simple cube using lines in 3D. This is fine if I use a solid line (no pattern). but I get an odd effect when I use linestipple to create a dashed line. When I move the camera around the dashes move up/down the length of the line. This looks wrong to me. I would like the dashes to not move along the lines as the camera is rotated. Is this possible?

Hi Darren, This will be a limitation with the implementation line stipple in OpenGL. I can't think of an easy solution to making sure the stipple is object space, the hard way would be to not use LineStipple but create the lines yourself and then use a 1D texture to create the stipple effect.
