Demo: Integrating OpenSceneGraph with Qt Quick

rooi

Hi Konstantin,

I recently got some more time to look into your project again. As I stated before I like the way you integrate osg and qt/qml.

I tried to extent the functionality by adding some osg pickers to allow identifying the name and type of a node underneath the mouse. This seems to work initially, but unfortunatly it doesn't after a resize of the window.

Do you have any idea why this occurs? My guess is that something does not get the new window size after a resize, but which object? Hopefully you could give me another pointer to try and get this fixed.

Thank you very much!

Hi,

I managed to get the picker to work by doing the following:

Add the following lines to updateViewport()
QSize size(quickItem->boundingRect().size().toSize());
if(view->getCamera()->getGraphicsContext())
view->getCamera()->getGraphicsContext()->resized( 0, 0, size.width(), size.height() );

Thanks.

Is someone can send me the demo ? I can't download it...

I am sorry, but the link to the archive is not working.
You can try to get the code via git:
@
git clone git://podsvirov.pro/osg/osgqtquick.git

Good news: a link to a screenshot and the source code in the archive is working again!

Hi Konstantin,

Sub: enable multisampling

Your example is really well done, Thanks. Now I want to enable multisampling, but I can not figure out how to enable it. I want to use the buffer mode.
The QOpenGLFramebufferObjectFormat.setSamples(4) does not seem to work. I don't have a very deep knowledge or osg::GraphicsWindow and its traits. But if you can guide me, I can take a look.

Thanks a lot,

@rooi
oh I am facing the same problem as you did. when I resize the windows ,it seems that the Qopenglcontext turn to null . so the fbo is initialized failed. using the method you give it does not work . i try to delete the updatafbo it works but the size of texture does not changed any more.
