Detailed Description

ShadowTechnique is the base class for different shadow implementations.

Constructor & Destructor Documentation

◆ ShadowTechnique() [1/2]

osgShadow::ShadowTechnique::ShadowTechnique ( )

◆ ShadowTechnique() [2/2]

osgShadow::ShadowTechnique::ShadowTechnique ( const ShadowTechnique es,
const osg::CopyOp copyop = osg::CopyOp::SHALLOW_COPY 
)

◆ ~ShadowTechnique()

Member Function Documentation

◆ className()

virtual const char * osgShadow::ShadowTechnique::className ( ) const
inlinevirtual

return the name of the object's class type. Must be defined by derived classes.

Implements osg::Object.

◆ cleanSceneGraph()

virtual void osgShadow::ShadowTechnique::cleanSceneGraph ( )
virtual

Clean scene graph from any shadow technique specific nodes, state and drawables.

Reimplemented in osgShadow::ParallelSplitShadowMap, osgShadow::ShadowMap, osgShadow::ShadowTexture, osgShadow::ViewDependentShadowMap, and osgShadow::ViewDependentShadowTechnique.

◆ computeOrthogonalVector()

osg::Vec3 osgShadow::ShadowTechnique::computeOrthogonalVector ( const osg::Vec3 direction) const
protected

◆ cull()

virtual void osgShadow::ShadowTechnique::cull ( osgUtil::CullVisitor cv)
virtual

◆ dirty()

virtual void osgShadow::ShadowTechnique::dirty ( )
inlinevirtual

Dirty so that cached data structures are updated.

Reimplemented in osgShadow::ViewDependentShadowTechnique.

◆ getShadowedScene() [1/2]

ShadowedScene * osgShadow::ShadowTechnique::getShadowedScene ( )
inline

◆ getShadowedScene() [2/2]

const ShadowedScene * osgShadow::ShadowTechnique::getShadowedScene ( ) const
inline

◆ init()

virtual void osgShadow::ShadowTechnique::init ( )
virtual

◆ isSameKindAs()

virtual bool osgShadow::ShadowTechnique::isSameKindAs ( const osg::Object obj) const
inlinevirtual

Reimplemented from osg::Object.

◆ libraryName()

virtual const char * osgShadow::ShadowTechnique::libraryName ( ) const
inlinevirtual

return the name of the object's library. Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Implements osg::Object.

◆ releaseGLObjects()

virtual void osgShadow::ShadowTechnique::releaseGLObjects ( osg::State = 0) const
pure virtual

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Object.

Implemented in osgShadow::DebugShadowMap, osgShadow::ParallelSplitShadowMap, osgShadow::ShadowMap, osgShadow::ShadowTexture, osgShadow::StandardShadowMap, osgShadow::ViewDependentShadowMap, and osgShadow::ViewDependentShadowTechnique.

◆ resizeGLObjectBuffers()

virtual void osgShadow::ShadowTechnique::resizeGLObjectBuffers ( unsigned int  maxSize)
pure virtual

◆ setShadowedScene()

virtual void osgShadow::ShadowTechnique::setShadowedScene ( ShadowedScene ss)
virtual

◆ traverse()

virtual void osgShadow::ShadowTechnique::traverse ( osg::NodeVisitor nv)
virtual

◆ update()

virtual void osgShadow::ShadowTechnique::update ( osg::NodeVisitor nv)
virtual

run the update traversal of the ShadowedScene and update any local cached data structures.

Reimplemented in osgShadow::ParallelSplitShadowMap, osgShadow::ShadowMap, osgShadow::ShadowTexture, osgShadow::ViewDependentShadowMap, and osgShadow::ViewDependentShadowTechnique.
