[osg-users] Offline screen render without pbuffer on virtual machine
Hi, I have an application, that renders offline, and the rendered result is displayed by WPF control, copying osg::Image to System.ImageControl (c#). Using the application on a normal PC, every thing was going well, till i wanted to test the application on VirtualBox, and VMWare. And getting either nothing or a complete crashes. I Debigged the application and i noticed on the VM, the graphic context is not created, cause is need : PixelBufferWin32, which it needs WGLExtensions, which it need wglCreatePbufferARB. wglCreatePbufferARB :(WGL_ARB_pbuffer) is not supported by OpenGL for VM. I tried : VirtualBox with OpenGL 2.1 and VMWare with OpenGL 3.1. Any suggestions ? Thank you!

[osg-users] osgUtil::PlaneIntersector and Invalid Pointer and Tesselation Error
Hi,
I am using plane intersection to get the intersection of all meshes in my scene
with a plane. :
Code:
osg::ref_ptr intersector = new
osgUtil::PlaneIntersector(mIntersectionPlane);
intersector->setRecordHeightsAsAttributes(true);
intersector->setPrecisionHint(osgUtil::PlaneIntersector::PrecisionHint::USE_DOUBLE_CALCULATIONS);
osgUtil::IntersectionVisitor mIntersectionVisitor; // Defined as a member
usually
mIntersectionVisitor.reset();
mIntersectionVisitor.setTraversalMask(utils::MASK_SCENE_DATA);
mIntersectionVisitor.setIntersector(intersector.get());
view->getSceneData()->accept(mIntersectionVisitor);
osgUtil::PlaneIntersector::Intersections& intersections =
intersector->getIntersections();
and in another function : i am computing the corresponding geode to the
intersections:
Code:
inline osg::ref_ptr getSlice(const
osgUtil::PlaneIntersector::Intersections & intersections)
{
osg::ref_ptr geode = new osg::Geode;
osg::ref_ptr geometry = new osg::Geometry;
osgUtil::Tessellator tessellator;
// set the normal in the same way color.
osg::ref_ptr normals = new osg::Vec3Array;
// Compute Vertices
osg::ref_ptr vertices = new osg::Vec3Array;
for (const auto& intersection : intersections)
{
for (const auto& vertex : intersection.polyline)
{
vertices->push_back(vertex);
normals->push_back(osg::Vec3(0.0f, 0.0f, 1.0f));
}
vertices->push_back(*intersection.polyline.begin());
normals->push_back(osg::Vec3(0.0f, 0.0f, 1.0f));
vertices->push_back(*intersections.begin()->polyline.begin());
normals->push_back(osg::Vec3(0.0f, 0.0f, 1.0f));
}
geometry->setVertexArray(vertices);
geometry->setNormalArray(normals, osg::Array::BIND_OVERALL);
geometry->addPrimitiveSet(new osg::DrawArrays(GL_POLYGON, 0, vertices->size()));
tessellator.setWindingType(osgUtil::Tessellator::WindingType::TESS_WINDING_NONZERO);
tessellator.setTessellationType(osgUtil::Tessellator::TESS_TYPE_GEOMETRY);
tessellator.retessellatePolygons(*geometry);
geode->addDrawable(geometry.get());
geode->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::ON);
return geode.get();
}
Now :
My first Problem is : Somtimes thee last element in the NodePath of
Intersections in the intersection is an invalid pointer, I don't Know why.
My Secend Problem is : Somtimes when i have meshes with Holes, the Holes are
not Computed, all the mesh is filled.
Thank you!
Cheers,
Théo

[osg-users] osgFX::Outline and Stencil
Hi,
I have Two views in my scene, both of them are in a Composite Viewer. I have
added the outline to the truck, and then i have added the truck to my scene.
Why only under the viewport of the cube i have the outline.
Here is a part of my code, and i have attached an image of the result
///OSG Scene : View
osg::ref_ptr mView;
osg::ref_ptr mCubeView;
///OSG Scene : Viewer
osg::ref_ptr mViewer;
...
osg::ref_ptr ds = osg::DisplaySettings::instance();
ds->setMinimumNumStencilBits(8);
mView->getCamera()->setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT |
GL_STENCIL_BUFFER_BIT);
mView->getCamera()->setClearStencil(0);
mView->getCamera()->setViewport(new osg::Viewport(0, 0, mTraits->width,
mTraits->height));
mViewer->addView(mView.get());
mCubeView->getCamera()->setClearMask(GL_DEPTH_BUFFER_BIT |
GL_STENCIL_BUFFER_BIT);
mCubeView->getCamera()->setRenderOrder(osg::Camera::POST_RENDER);
mCubeView->getCamera()->setClearStencil(0);
mCubeView->getCamera()->setViewport(new osg::Viewport((mTraits->width - 175),
(mTraits->height - 175), 150, 150,));
mViewer->addView(mCubeView.get());
...
mView->setSceneData(mSceneData.get());
...
{
osg::ref_ptr outlineModel =
osgDB::readNodeFile("D:\\Data\\New_Test\\OpenSceneGraph-3.4.0\\OpenSceneGraph\\build\\x64\\bin\\dumptruck.osgt");
// create outline effect
osg::ref_ptr outline = new osgFX::Outline;
mSceneData->addChild(outline.get());
outline->setWidth(8);
outline->setColor(osg::Vec4(1, 1, 0, 1));
outline->addChild(outlineModel.get());
}
Thank you!
Cheers,
Théo
