[osg-users] how to make a node fixed in screen position
hi all,
I want to draw axes in screen position,the axes can't be scaled or
transformed ,but which can be rotated with other scene.I do it like this,but
the billboard (texts: 'X','Y','Z') doesn't work,what should I do to make the
billboard work well？“axes.osg” is downloaded from the osg homepage.
osgViewer::Viewer viewer;
class orbit : public osg::NodeCallback
{
public:
orbit() {}
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::PositionAttitudeTransform *pat =
dynamic_castosg::PositionAttitudeTransform *(node);
if( tx != NULL )
{
osg::Camera *camera=viewer.getCamera();
osg::Matrixd pMatrix = camera-getViewMatrix();
pat-setAttitude(pMatrix.getRotate());
}
}
};
osg::Group* fun()
{
osg::Group *group=new osg::Group();
osg::Node *axis=osgDB::readNodeFile(data\\axes.osg);
osg::PositionAttitudeTransform * tran = new osg::PositionAttitudeTransform;
tran-addChild(axis);
tran-setPosition(osg::Vec3(5,5,0));
tran-setUpdateCallback(new orbit());
osg::MatrixTransform* ModelViewMatrix = new osg::MatrixTransform;
ModelViewMatrix-setMatrix(osg::Matrix::identity());
ModelViewMatrix-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
ModelViewMatrix-addChild(tran);
osg::Projection* ProjectionMatrix = new osg::Projection;
ProjectionMatrix-setMatrix(osg::Matrix::ortho2D(0,10,0,10));
ProjectionMatrix-addChild(ModelViewMatrix);
group-addChild(ProjectionMatrix);
return group;
}
int _tmain(int argc, _TCHAR* argv[])
{
osg::Group *mRoot =fun();
viewer.setSceneData(mRoot);
return viewer.run();
}
best regards

[osg-users] Strange behavior with multiple screens and ImageStream
Hi all, We've made an ImageStream using FFmpeg to display movies on textures, but I am currently facing some problem when displaying this movie on two different contexts. Here is my setup : WinXP with one GForce 8600GTS and 2 screens, viewer on DrawThreadPerContext mode (OSG SVN head version). When I only have one screen but two windows (with a different context per window), everything works fine, the movie is displayed on the 2 windows without any problem. When I plug a second screen, and I keep the same setup (2 windows rendered into the first screen), I have a huge frame drop (more than 20 fps) when rendering my movie (note that in this configuration, nothing is displayed on the second screen). Same thing happens if I use the 2 screens (with each window in full screen mode on each screen). I really don't understand why adding a new screens make this difference, moreover it's the only thing in my application that suffer like that from the second screen. Does it ring a bell to someone ?

Re: [osg-users] painting plane
Hi Ilia, If one side of the plane should be red, and the other blue then you could render two polygons for the plane, each with opposite winding and colour, then use glCullFace(osg::CullFace) to cull the faces to give the illusion of changing colour. The other technique you could use of two sided colour in the OpenGL lighting/material model, not all hardware/drivers supports two side lighting though. Robert.

Re: [osg-users] Mac OS X 10.5 crash in osgText
Hi Hartmut, The FreeType plugin usage is guarded to prevent thread problems so while FreeType isn't thread safe, this shouldn't affect OSG-2.6, and almost certainly has no barring on the crash you describe. The crash you looks to be CGL issue, whether this is a threading issue or otherwise I cannot say at this stage. Try chnaging the threading models in osgviewer by pressing 'm', or run the app with the command line option --SingleThreaded etc. Robert.

[osg-users] fish eye projection
Hi, I need to output to a single channel fish eye projection lens .
(Elumenati system) Is there a simple way to achieve this?
Basically I believe there are 3 paths to chose from:
1. doing the fisheye projection yourself (similar to osgdistortion)
2. using the elumentai api, omnimap (only windows so I'm not to keen on
this)
3. configuring osgViewer in some way?
1 and 2 is obvious but requires some work. I am hoping for 3 since I found
files called *.view in the {$OSG_FILE_PATH}/Configuration folder. I have not
found documentation on how to create or use those files so if someone has a
pointer for me to start reading it would be great :)

Re: [osg-users] fish eye projection
Ok, I searched and tested a little bit more. Using -c congfigfile.view
should have been the first thing to try out. Sorry about that. But anyway,
Is there some documentation of how the rendering is set up etc?
Complications etc? Would be nice to understand and be able to change
depending on the needs that occurs.

Re: [osg-users] fish eye projection
Hi Filip,
If you system is a relatively common configuration then we might be
able to add a View::setView*() and associated support into .view
format, this way others will benefit and will be able to test the
functionality.
The way I developed the spherical display support was by creating
experimental code in the osgdisortion example, then when it was ready
I moved the code into osgViewer::View, then further evolve the code
from there. Perhaps the same approach might work for you.

Re: [osg-users] OverlayNode bug
Hi Robert, 2008/9/10 Robert Osfield [EMAIL PROTECTED] Hi Mathieu, I don't know the cause/or a solution to the problem, but in the case of VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY a GLSL vertex and fragment program is used to generate the results, so I'd guess that the shader simply doesn't know about the texture blending required. Have a look into the implementation to see if you can get things work. Some updates : The fragment shader correctly uses the overlay alpha color value to mix between the original texture and the overlayed texture. So it is not the shader that is the problem but the RTT camera that produces something wrong. By tweaking the fragment shader to use the alpha channel on the color channels it appears that the background of the overlay texture is transparent and the projected objects are opaque (where they should be transparent).

Re: [osg-users] Open/Close the window on win32
Hi, Recycling context id's is something that seems fixed in 2.6.0. I'm not sure if you can keep a graphics context around without a window however you can keep the scene graph around. Just hold onto a ref ptr to the root node of your scene graph. You should be able to open a new window and create a new viewer and pass in the root node of the SG you've kept around. (I'm not sure if video's/ animations will still be played though. Try it out.) Thanks, Brett christophe loustaunau wrote: Hello, This is something I'd like to make available as well.

Nice to hear! I don't have access to the actual inflatable dome at this time but I am trying to do a quick-and-dirty app to help me display media and models for testing purposes.

Personally I have integrated our rendering backend here at work with both OmniMap and EasyBlend (still based on OSG 2.2, but moving to 2.6 soon). * OmniMap does only fisheye correction * EasyBlend does correction for a variety of display geometries (dome, cylinder, etc) and edge blending for any number of projectors. Though the initial integration needed some care, we now have a setup that is not limited in terms of threading. We can use any threading mode that OSG supports with both integrations. And in both cases the actual integration needed just a simple class of about 150-200 lines, nothing really complicated. Yes, they are Win32 only though. But they were pretty straightforward to integrate, and the automatic calibration done by EasyBlend (it uses a digital camera and analyzes the resulting images to calibrate itself) saves us a lot of time in the field.

Re: [osg-users] painting plane
Ok. Coming back to first letter - what is right way to do such painting? As I understand, proper way to change scene - is using UpdateCallback. But in UpdateCallback there is no camera information. So I can't define suitable color for lines. In CullCallback there is camera information, but it's forbidden to change scene in CullCallback. It's possible to save reference to camera object in UpdateCallback descendant. Is it correct way?

Re: [osg-users] painting plane
Hi Ilia, The way I'd do it be to use a cull callback that decides between two subgraphs to traverse, one for the front face, one for the back, this would mean that your scene graph doesn't change with the viewport, and it'll scale nicely on multi-threaded and multi-camera setups. The other approach would be to use a vertex shader to change the light, or to use two sided lighting, which if you orientate the normals on the light correctly will work for you. Robert.

This is OSG 2.6 branch This is replicable with plain osgviewer on OSX on a MBP 2.4 To replicate: export OSG_WINDOW='20 20 800 600' open osgviewer cow.osg press 's' to show the stats with '' and '' go up and down the window resolutions ... it crashes always at the same point ... see below Is there any solution? If so will it be backported to 2.6? Cheers, Hartmut Process: osgviewer [1487] Path:/usr/local/bin/osgviewer Identifier: osgviewer Version: ??? (???)
