Hi, I am trying to implement the 3D overlay above current view. I am trying to set the camera background color as transparent. I am using following code.
osg::Node* node= osgDB::readNodeFile( "Models/cessna.osg"); osg::Camera* camera = new osg::Camera; camera->setViewport( 0, 0, 200, 200 ); camera->setClearColor(osg::Vec4(1.0f,1.0,0.8f,0.2f)); osg::StateSet* stateset = camera1->getOrCreateStateSet(); stateset->setMode(GL_BLEND,osg::StateAttribute::ON); stateset->setRenderingHint(osg::StateSet::TRANSPARENT_BIN); camera->setStateSet(stateset); camera->setRenderOrder( osg::Camera::POST_RENDER ); camera->setAllowEventFocus( true ); camera->setClearMask( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT ); camera->setReferenceFrame( osg::Transform::ABSOLUTE_RF ); camera->addChild( node1 ); Above code only set the white background. Please help to set the camera backgroud color as transparent.
