[osg-users] drawing line geometry on a 2D ortho viewport
Hello,
im sorry to keep asking for help but
im totaly stuck on trying to draw prmitive
geometry to a 2D ortho screen in OSG.
Ive been experimenting with both the
OSGhud and OSG geometry examples an i have
just ended up with a huge mess, with no visible
results.
I have taken the OSG geometry example
and i can compile and run it fine and see
the lines and polygons. I have then
converted the viewer camera to a 2Dorth projection
matrix, but in doing so i get no geomtry
visible. In addition it seems the gemoetry
example is still rendering the geomtry in
3d space with Vec3 required for the vertex
points,
but in the native opengl examples i
have seen on the net they use Vec2 for simple
X,Y.
this is the original main code from
the OSG geometry example
int main(int,
char **)
{
// create
the model
osg::Group* root = new osg::Group;
root-addChild( createScene() );
root-addChild( createBackground()
);
//osgDB::writeNodeFile(*root,"geoemtry.osg");
osgViewer::Viewer viewer;
// add
model to viewer.
viewer.setSceneData( root );
return viewer.run();
}
can any help me by showing how the viewer
camera can be set to 2D orth, no quad, no
background,so that one can still see the
geometry rendered on screen.
Everytime i set it to 2D ortho no geometry
is ever visible.
Any help appreciated, im tearing my hair
out, and have no idea what to try next.

Re: [osg-users] drawing line geometry on a 2D ortho viewport
Hi
thanks for that
i got that to work,
but i dont understand
why the bellow option where i adjust the
viewer camera directly does not work as well
?
It only seems to
work if i set them as nodes and add as childs.
Why is that ?
It seems to me to
be doing the same thing
In addition i assume
1.using the
ABSOLUTE_RF option sets the view matrix to
the default opengl (is that right ??) is
it the same as the default opengl glLoadidentity
for a different axis alignment
2. then i
would have to use osg:Matrix rot;
rot.makeRotate(90,osg::Vec3(1,0,0));
to rotate the matrix so that i have a +x(right),
+Y (up) axis alignement.
int main(int, char
**){
// create the model
osg::Group* root = new osg::Group;
root-addChild( createScene() );
osgViewer::Viewer viewer;
viewer.getCamera()-setProjectionMatrixAsOrtho2D(-2,2,-2,2);
viewer.getCamera()-setViewMatrix(osg::Matrix::identity());
// add model
to viewer.viewer.setSceneData(
root );return
viewer.run();}
thanks for any help
Peter
Hi,try
this modified code and compare with the unchanged
example. You can use ABSOLUTE_RF as well,
you will just need to rotate the matrix for
the viewer's default camera. Or change
the default camera to be in your coord
system.From the transform callback
you can see that the default view direction
of the camera is aligned with the y-axis.transform-setMatrix(osg::Matrix::translate(0.0f,1.0f+cosf(time*_angular_velocity),0.0f));Therefore,
the flat geometry will be drawn in the x-z
plane (as you can see from the example's
geom).You can use the 3rd coordinate
of your geometry to place different things
at different ranges (layers) from the camera.cheersjpint

[osg-users] loading a bitmap and displaying it
Hello i want to load a bitmap image and display it in osg. I wasplaning to emulate the osgHUD example and load a bitmap, map it to a quadstrip as a texture and addit as a child to the root node, using a ortho2d matrix for the camera. is this the only way to display a full screen bitmap in OSG ? And is there a way i could draw to the screen instead of loading a bitmap ?

Re: [osg-users] finding image files and how to correctly exit and osg application
Hi Robert, i was tripping myself up. When i was running the release exe outside the VS enviroment, it was not finding either the image file or the third party dll to load the image file. Then when i run it 3 times or more it would get locked to a XP os process. I dont know why. It seems to work ok now that the exe can file the images and dll. thanks Peter Hi Peter,The OSG itself doesn't lock files, it typically just open, reads thencloses them, so the culprit is almost certainly the OS or VisualStudioscrewing things up. Curiously I haven't heard of other with thisproblem. What OS are you working on?Another issue that seems to haunt Windows users is the various MSlibrary dependencies that VS requires, could it be that somethinghasn't been installed correctly on the other machines.Robert.On Jan 17, 2008 5:51 AM, Peter DeSantis [EMAIL PROTECTED] wrote: Hi i have successfully used cmake to build osg 2.2.0 with visual studio 2008.

Re: [osg-users] stereo projector support in OpenSceneGraph
Hi , i do heaps of stereoscropic stuff with quadro cards. If you your projector takes 2 input sources, you can try connect to the two dvi ports on a single quadro card. then go the driver of the quadro card driver section and put the qudro into clone mode so that you get the same single desktop display on both outputs. The go to the advanced properties section on the quadro card and enable the stereoscopic feature, then select "clone mode stereo" as the stereo type. Then you can run any stereoscopic application that uses the standard "quad buffer frame sequential" opengl sterescopic format and the quadro driver will auto convert it to the clone stereo mode. In addition of course you could also try putting the quadro card into a dual view display mode, ignore everything i said above and run you application in a "dual screen" stereo format. I think openscenegraph supports both the bove stereo formats i mention. Its also usefull to understand exactly the format your projector is expecting as well. Peter Hi, our lab get a new stereo projector connects to two video outputs on one Quadro FX 5500. Does OpenSceneGraph support such stereo display? I used to do stereo display using two machine and now I have no idea how to do it using one single video card. Anyinformation will be appreciated.

Hello i have been trying to use cmake to compile osg src examples such as the osgteapot example, so that i can use it as a starting bas to learn osg. So far i have had no success. I have visual studio 2008 pro installed on XP sp2. I have osg 2.2 and can run all the pr compiled examples ok. if i use cmake-2.4.8-RC-11-win32-x86.exe and select visual studio 9 2008 in the configure option then i get an error saying it was unable to find a build program corresponding to visual studio 9 2008. if i use cmake 2.5, it successfull finds visual studio 9 2008 then begins the build process till it gets to about 10% then every single time it throws up and error that reads "unknown cmake command SETUP_EXAMPLE" and then i cannot get past this point.

[osg-users] what binaries and libs can be used with visual studio 2008 ?
Hi just 2 questions. 1. Can the visual studio 2008 use the compiled win32 binaries and libs in the osg 2.2 release or not ? I seen a lot of to and fro about this issue on the mailing list and wonder can some one give me a definite answer on this. If the naswer is no, then what do i need to do to get compatiable libs or binaries to use with visual studio 2008 ? 2. My c++ is a bit rusty, but when you link the libs into your project, and build a final result does it not embed the libs into you application exe and eleiminate the need for the run time osg DLL's. I thought that was the reason to link in the libs ? If this is not the case why not ? and then what exasctly is needed to run a final application on a XP/vista machine that has a clean install of the os ? EG osg runtime dll + c++ runtime or what ?

I am using OSG 2.0.0 as specified at the wrapper download page. If you have any thoughts it would be appreciated. Peter DeSantis Hi Gavin,Peter DeSantis sent me an email offline and I sent him the project file I'm using. Here is the entire project.
