Hi all,I am trying to use overlay node to overlay a sphere on top of a cylinder, but i am getting the black area(Clear color) around the sphere as shown in the snapshot. Ideally i want to have just sphere on top of cylinder. My code for setting the overlay is
// Create overlay node osg::ref_ptr<osgSim::OverlayNode> olNode =new osgSim::OverlayNode(osgSim::OverlayNode::OBJECT_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY);
olNode->setOverlaySubgraph(sphNode); olNode->setRenderTargetImplementation(osg::Camera::FRAME_BUFFER); olNode->setOverlayTextureSizeHint(1024); olNode->setOverlayBaseHeight(0.0); olNode->setTexEnvMode(GL_BLEND); olNode->setOverlayClearColor(osg::Vec4(1.0, 0.0, 0.0, 0.0)); osg::ref_ptr<osg::Group> grpNode = new osg::Group;olNode->addChild(cylNode);
Can someone tell me what am i doing wrong ? -- Rahul Jain, Member of Technical Staff, Visualization Experts Limited. www.vizexperts.com+91-98109-83697 (M)
