Ok, I've discovered the seemingly innocuous problem. When I had tried to
comment out all the shader related code in the GetGeode function, I was left
with this:
Code:
osg::Geode* getGeode( osg::Texture2D& targetTexture )
{
osg::Geode* geode = new osg::Geode;
geode->setName("quad");
osg::Vec3 llCorner = osg::Vec3(-0.5,0,-0.5);
osg::Vec3 width = osg::Vec3(1,0,0);
osg::Vec3 height = osg::Vec3(0,0,1);
//////////
// QUAD //
//////////
osg::Geometry* geom = osg::createTexturedQuadGeometry( llCorner, width,
height );
geode->addDrawable( geom );
geode->getOrCreateStateSet()->setTextureAttribute( 0, &targetTexture,
osg::StateAttribute::ON );
return geode;
}
This code resulted in this:

Instead of this:

The problem was with the use of setTextureAttribute function. I was seeing the
osg::StateAttribute::ON parameter and was fooled into thinking that was doing
something. So substituting setTextureAttributeAndModes did the trick. Lesson
learned. Thanks Mick.
