Hi Jean-Sébastien,
Using a HUD-like system seems to be a extrem solution for me... I am just
looking at a way to set a node always rendered...
For the moment, using the .osg format file to see my stateset, I see that
the culling test still stay ON.
I correct it ; my code is now :
* node->setCullingActive(false);
osg::ref_ptr<osg::Depth> depth = new osg::Depth(osg::Depth::NEVER, 0.0,
1.0);
node->getOrCreateStateSet()->setAttributeAndModes(depth.get(),
osg::StateAttribute::ON);
node->getOrCreateStateSet()->setMode(GL_DEPTH_TEST,
osg::StateAttribute::OFF);
node->getOrCreateStateSet()->setRenderBinDetails(1000, "RenderBin");*
my node is now :
*PositionAttitudeTransform {
UniqueID PositionAttitudeTransform_0
name "F-GHOP"
nodeMask 0xffffffff
cullingActive FALSE
StateSet {
UniqueID StateSet_1
rendering_hint DEFAULT_BIN
renderBinMode USE
binNumber 1000
binName RenderBin
GL_DEPTH_TEST OFF
GL_NORMALIZE ON
Depth {
UniqueID Depth_2
function NEVER
writeMask TRUE
range 0 1
}
}
UpdateCallbacks {
NodeCallback {
name "planeOverTheFloorCallback"
NodeCallback {
name "triggerScaleCallback"
}
}
}
...
//with LOD children after.*
And the result... still the same : culling make nothing different.
Am I missing something important ?
thanks,
Regards,
Vincent.
