Re: [osg-users] osg::Node can not be displayed front of the Earth on the screen

if you need to draw anything on the center of the screen in front of something else, then your problem is to create an ortho camera and have your geometry there - something like HUD. The osghud example shows how to do this. Just for a test, you can use the createHUD() function from that sample to c

Hi Antoine, You can just do your glReadPixels(..) or osg::Image::readPixels(..) in your own Camera::DrawCallback that you attach as a post draw callback to your camera. Robert. On 2 March 2018 at 16:12, Antoine Rennuit wrote: > Hi all, > > Hum, it seems my case is a bit more complex than expect

Re: [osg-users] Read frame buffer back into main memory

Hi all, Hum, it seems my case is a bit more complex than expected. The camera I want to read the buffer from is a custom created camera: Code: // Curvatures camera. m_curvaturesCamera = new osg::Camera(); m_curvaturesCamera->setClearMask(GL_DEPTH_BUFFER_BIT); // The camera only cle

Hi, i have a similar problem and dont want to create a new thread. Unfortunately i couldnt fix the problem with these solutions here. What you can see is the back of a plane with enabled front (transparency) or back (black/no lightning) face culling.[/img] OSG Version:

I could not relate the example with my question. I am using osgEarth. Can you be more expressive what causes this? Thanks, Trajce Nikolov NICK wrote: > Hi Ali, > > have a look at the osghud example from the osg repo > > > On Fri, Mar 2, 2018 at 1:44 PM, Ali Ozdin < ()> wrote: > > > Hi, > >

Hi, I drew an osg Node and I want to put it on the center of the screen like any labelControl. How can I do that? I put a sample code below. If I change the line from Code: viewer.setSceneData( mainGroup ); to Code: viewer.setSceneData( nn.get() ); and remove these two lines Code: mani

Hi Sebastian, Geode {... Geometry { ... StateSet { ... GL_CULL_FACE ON Material { } CullFace {

Hi, What is the correct syntax to enable front or backface culling in an osg file? For example: Geode {... Geometry { ... StateSet { ... GL_CULL_FACE ON ...
