[osg-users] Problems with osgFX::Outline node

[Gianni Ambrosio]

Hi All,
I found at least two problems related to osgFX::Outline.

First of all, turning off lightning on a child node then the outline seems inheriting that option.

Here is basically the code:


Code:

void ControlPoints::insertMarker(size_t iIndex, const viframework::vimath::Point<double>& iPoint)
{
   osg::ref_ptr<osg::AutoTransform> transform = new osg::AutoTransform();

   transform->setAutoRotateMode(osg::AutoTransform::ROTATE_TO_SCREEN);
   transform->setAutoScaleToScreen(true);
   transform->setMinimumScale(0.0);
   transform->setMaximumScale(FLT_MAX);

   transform->setPosition(osg::Vec3(iPoint.x(), iPoint.y(), iPoint.z()));
   transform->addChild(buildFlagWithOutlineEffect(30.0));
   root->addChild(transform);

   viroad::viosg::SceneManager::instance().setDirty();
}

osg::Node* ControlPoints::buildFlagWithOutlineEffect(float height)
{
   osgFX::Outline* outline = new osgFX::Outline;
   outline->setWidth(5);
   outline->setColor(osg::Vec4(1.0f, 0.0f, 0.0f, 1.0f));
   Flag* flag = new Flag(height);
   //flag->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF);
   outline->addChild(flag);
   return outline;
}




In attachment you can see the different behaviour.
I would like to disable lightning on the flag but have a red outline.

About the second problem I will open a different topic.

Cheers,
Gianni
