Hi all,
I have a problem when trying to use the stereo mode HORIZONTAL_INTELACE
with a viewer that is integrated into Qt utilizing the QOpenGLWidget: It
doesn't work.
My integrated viewer class subclasses QOpenGLWidget as well as the
osgViewer::Viewer.
In my initialization routine I create a graphic context like this:
osg::DisplaySettings::instance()->setNumMultiSamples(DEFAULT_MULTISAMPLING);
osg::ref_ptr<osg::GraphicsContext::Traits> pTraits = new
osg::GraphicsContext::Traits;
pTraits->x = 0;
pTraits->y = 0;
pTraits->width = DEFAULT_SCREEN_WIDTH;
pTraits->height = DEFAULT_SCREEN_HEIGHT;
pTraits->doubleBuffer = true;
pTraits->stencil = 8;
mpGraphicsWindowEmbeddedContext = new
osgViewer::GraphicsWindowEmbedded(pTraits.get());
I use this graphics content and set it to the render camera:
mpRenderCamera->setGraphicsContext(mpGraphicsWindowEmbeddedContext);
mpRenderCamera->setViewport(0, 0, DEFAULT_SCREEN_WIDTH, DEFAULT_SCREEN_HEIGHT);
mpRenderCamera->setClearMask(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);
mpRenderCamera->setClearColor(osg::Vec4(DEFAULT_BG_COLOR_R, DEFAULT_BG_COLOR_G,
DEFAULT_BG_COLOR_B,
DEFAULT_BG_COLOR_A));
For my QOpenGLWidget I have set my QSurfaceFormat like this:
QSurfaceFormat format(QSurfaceFormat::defaultFormat());
format.setSamples(DEFAULT_MULTISAMPLING);
format.setStencilBufferSize(8);
setFormat(format);
When I run my code I only see the image for the left eye without any
interlacing by the image for the right eye.
I also tried the viewer from https://github.com/openscenegraph/osgQt but it
gives me the same result.
I suppose it has something to to with the stencil buffer, but I don't know
how to fix it. Can someone please help me?
Thanks in advance.
