[osg-users] Outlining a node (Beginner)

[Lex Wilk]

Hi,

I'm just starting out in OSG and have a basic robot arm model that I require an outline on a specific node. I have a nodeVisitor class which can find the node by name and I am stuck on outlining it.

Currently I am using this: 


Code:
findNodeVisitor findBNode("BodyRotator");
osg::Node* bodyNode = new osg::Node; 
g_pModel->accept(findBNode);
bodyNode = findBNode.getFirst();

osg::ref_ptr<osgFX::Outline> outline = new osgFX::Outline;
outline->setColor(osg::Vec4(1.0, 0.0, 0.0, 0.0));
outline->setWidth(100.0);
outline->addChild(bodyNode);
rootNode->addChild(outline);



But I only get a brief outline that flickers off after a second and only appears when rotating the robot arm. Does anyone have any pointers for getting this working?

Cheers,
Lex[/code]
