I have a few geometries where I would like the material to display on both sides and having the correct normals.
I have tried to just turn on the two sided light model, but things get
really ugly then.
Here is the material used...
osg::Material * matPin = new osg::Material();
matPin->setAmbient( osg::Material::FRONT_AND_BACK, OHole );
matPin->setDiffuse( osg::Material::FRONT_AND_BACK, OHole );
matPin->setSpecular( osg::Material::FRONT_AND_BACK, OHole );
matPin->setShininess( osg::Material::FRONT_AND_BACK, 64.0f);
osgHCore->m_OtherHoleSS = new osg::StateSet();
osgHCore->m_OtherHoleSS->setAttributeAndModes( matPin,
osg::StateAttribute::ON );
/************************************
osg::LightModel* lightmodel = new osg::LightModel;
lightmodel->setTwoSided( true );
osgHCore->m_OtherHoleSS->setAttributeAndModes(lightmodel,
osg::StateAttribute::ON );
************************************/
I've attached 2 images. cyl-wo-lightmodel.jpg has the lightmodel
commented out as shown above. cyl-w-lightmodel.jpg is with it
uncommented. (-with- & -without-).
Notice the weird lighting of the square pads. This material is only
attached to the hole cylinder geode.
Ideas?
Thanks,
Greg
