Hi Mark,
I can't think of a specific reason for the difference, perhaps a bug
fix has changed the behavior that you were once relying upon. Does
the osghud example work for you?
My best guess right now would be that geometry is outwith the near or
far clipping planes and the OSG 2.2 and 2.8.2 have changed the way
they are maintained. This is just clutching at straws though.
The best strategy for you might be to have a look at osghud and then
try and mimic what it's doing in your own code.
Robert.

Hi
I have been working for a few days on 2.8.2 to port my display system from
2.2. The 3D is displayed as I would expect, but unfortunately my HUD overlay
that worked in 2.2 is no longer being displayed. Anyone got any ideas? Below
is how I setup my HUD (just a series of lines that I update each frame)
// set the projection matrix
pHUDCamera-setProjectionMatrix(osg::Matrix::ortho2D(HUD_screen_min_x,HUD_screen_max_x,HUD_screen_min_y,HUD_screen_max_y));
// set the view matrix
pHUDCamera-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
pHUDCamera-setViewMatrix(osg::Matrix::identity());
// only clear the depth buffer
pHUDCamera-setClearMask(GL_DEPTH_BUFFER_BIT);
// Make sure HUD is last thing to be render; we want it always on top
pHUDCamera-setRenderOrder(osg::CameraNode::POST_RENDER);
pHUDCamera-addChild( pHUDGeode );
root-addChild( pHUDCamera ) ;
The line data is setup using
pHUDGeometry-setVertexArray(pHUDVertices);
pHUDGeometry-addPrimitiveSet(new
osg::DrawArrays(GL_LINES,0,number_of_HUD_vertices));
I have looked through the archive but have not found a solution. So I have
obviously missed something. Any suggestions would be much appreciated.
I’m using XP Pro, VS2005 v8
Thanks
