Hi, everyone!!javascript:emoticon(':)') I'm new to OSG and I am struggling
with applying both linear and exponential types of fog.
Would someone mind showing me what I'm doing wrong? Thx for the help! I really
appreciate it.
// Fog: Linear
osg::ref_ptr<osg::Fog> m_ofgFogLinear = new osg::Fog();
m_ofgFogLinear->setMode(osg::Fog::LINEAR);
//m_ofgFogLinear->setDensity(0.001); // makes NO diff for linear
m_ofgFogLinear->setColor( osg::Vec4d(.75,.75,.75,0.0));
m_ofgFogLinear->setStart(0.0);
m_ofgFogLinear->setEnd(5000.0);
osg::ref_ptr<osg::StateSet> stateFogOn=new osg::StateSet();
stateFogOn->setAttribute(m_ofgFogLinear.get(), osg::StateAttribute::ON);
stateFogOn->setMode(GL_FOG, osg::StateAttribute::ON);
stateFogOn->setMode(GL_BLEND, osg::StateAttribute::ON);
//FOG state: exponential
osg::ref_ptr<osg::Fog> m_ofgFogExponential = new osg::Fog();
m_ofgFogExponential->setMode(osg::Fog::EXP);
m_ofgFogExponential->setDensity(0.00005);
m_ofgFogExponential->setColor( osg::Vec4d(.75,.75,.75,0.0));
osg::ref_ptr<osg::StateSet> stateFogExpOn=new osg::StateSet();
stateFogExpOn->setAttribute(m_ofgFogExponential.get(),
osg::StateAttribute::ON);
stateFogExpOn->setMode(GL_FOG, osg::StateAttribute::ON);
stateFogOn->setAttribute(m_ofgFogExponential.get(), osg::StateAttribute::ON);
m_pognRoot->setStateSet(stateFogOn.get());
Isn't it possible to enable more than 1 attribute w/in a StateSet? I'm
trying to enable 2 types of fog w/in the same StateSet and it appears that only
one is actually in effect - the last one loaded.
