Hi Adrian,

I will check it. Hopefully tomorrow (tuesday) Maybe I will be able to find
what is wrong.

Cheers,
Wojtek

  I don't have any shadow,

  my scene look similar to the osgshadow one. but i have a strange
behaviour.

  pseudo code:
  osg::Group g
  osg::Lightsource s;

  shadowed->addchild(s)
  shadowed->addchild(g)

  viewer.setData(shadowed)

  i don't have light on, need state set to switch on light ()

      s->getOrCreateStateSet()->setAttributeAndModes(m_lightSource_Sun->getL
ight(),osg::StateAttribute::ON);

  and pssm does work, but lispsm not (event with setlight(s->getLight())

    Hi,

    What is wrong ? It does not work ? Method accepts Light ptr. If you have
LightNode simply use getLight() to pass right argument.

        Thank You, Adrian

        Lispsm classes derive all methods from StandardShadowMap &
MinimalShadowMap. StandardShadowMap has setLight method. I believe this is
what you want.

          Sorry, answered to  wrong list
          but here i am right :-)


          Hi all,

          great algorithm. i have just one question. my scene has a lof of
lighs, but only one should cast shadows. so would it be possible to add a
method like in parallel splitted shadow map to tell the algorithm witch
light it should be used for shadow casting.

          please have a short look at :
                  _ParallelSplitShadowMap->
          setUserLight(m_sun.get());

          this method allow to tell the sun light. :-) for example
