Thank your for your reply, Stephan.
You were right. I changed my code:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
osg::setNotifyLevel(osg::DEBUG_INFO);
_viewer = new osgViewer::Viewer();
_root = new osg::Group;

Hi,
I am trying to learn OSG for iPhone.
For this I am using the simpleExample on https://github.com/stmh/osg.
Instead of the blue background color I want to load an Image.
I already look at the osgHud.cpp example and I try to use some code lines.
Now, I can see the child-node with geode

All I can see is that you are creating a finalDrawCallback to save the

Hi,
I would like to put an quad as background, i would like to know if it is
possible to have the required size to do this. (eg: if zFar is at 10 000 how is
height and how is height?)
thanks a lot !

Hi Anthony,
I'd rather use a HUD-like technique as shown in the osghud example. The

I'd like to create a fixed background for an osg application, much like a
HUD but while the HUD is always on top of the scene, I need to have an image
always behind any 3D object.
I tried to modify the example about HUDs by changing:
setRenderOrder(osg::Camera::POST_RENDER);
into this:
Hi Alessandro,
nah. That wont do the job. I did a quick test, and here is how I made it
work
go the the osgHUD example and:
1. createHUD, set for the camera:
camera-setRenderOrder(osg::Camera::NESTED_RENDER);
2. in main, about line 362, where you load your scene without arguments
Thank you very much Nick, it worked fine, I just changed this:
group
-getOrCreateStateSet()-setMode(GL_DEPTH_TEST,osg::StateAttribute::OFF);
into this:
one-getOrCreateStateSet()-setMode(GL_DEPTH_TEST,osg::StateAttribute::OFF);
Regards.

There is DepthSortedBin as well
osg::ref_ptrosg::Group group = new osg::Group;
osg::Node* one = createHUD(); // this will be your background image
osg::Node* two = scene.get();
one-getOrCreateStateSet()-setRenderBinDetails(1,DepthSortedBin);
You can use an additional Camera for this, but that's really overkill
for a fullscreen quad.
I would just draw a quad. Use a low render bin so that it renders first.
Use a vertex shader to do the transform (make it fullscreen and put it
on the far plane) and a fragment shader for the
Hi !

Hi Carlos,
you need to put the HUD in a render bin that is drawn before everything else.
Setting the render bin to 0 or 1 should work (because I think other
geometry would default to bin 2)
The HUD also needs to be configured to not write to the z buffer.

I tryed disabling the resize of non power of two textures by using
setResizeNonPowerOfTwoHint but it did not seem to have any effect.
Do you think there is a bug or I just wasnt doing something right? You
can find the line where I tried this in my original post.
I havent been able to figure out
