Hi,
I'm using osgShadow::ShadowedScene to render shadows using shadowmap. The
shadows are rendered correctly. As my scene graph gets complex i want to add
the ShadowedScene as a child to another node as shown below
Code:
ref_ptr<Group> scene (new Group);
//Main light source
Vec3 lightPosition(0,0,3);
LightSource* ls = new LightSource;
ls->getLight()->setPosition(Vec4(lightPosition,1));
ls->getLight()->setAmbient(Vec4(0.2,0.2,0.2,1.0));
ls->getLight()->setDiffuse(Vec4(0.6,0.6,0.6,1.0));
//Shadow stuff!!!
ref_ptr<osgShadow::ShadowedScene> shadowedScene = new
osgShadow::ShadowedScene;
ref_ptr<osgShadow::ShadowMap> sm = new osgShadow::ShadowMap;
shadowedScene->setShadowTechnique(sm.get());
sm->setTextureSize(osg::Vec2s(2048, 2048));
sm->setTextureUnit(1);
sm->setLight(ls);
// Shadowed scene added as a child to scene
scene->addChild(shadowedScene.get());
// Set scene data
viewer.setSceneData(scene.get());
As shown above if i add the shadowedScene to scene and set the scene data to
scene, the shadows are not getting rendered. If i set the sceneData to
shadowedScene the shadows are rendered correctly. But the scene graph has some
other elements such as ODE physics, shaders applied to some nodes etc., are
getting disabled if i set sceneData to shadowedScene.
Please provide some suggestions on how to get the shadow effect by by adding
the shadowedScene as a child
Thank you!
Cheers,
Saravanan
