Constructor & Destructor Documentation

osg::LightSource::LightSource ( )
osg::LightSource::LightSource ( const LightSource ls,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)
inline

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

virtual BoundingSphere osg::LightSource::computeBound ( ) const
virtual

Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().

Reimplemented from osg::Group.

Light* osg::LightSource::getLight ( )
inline

Get the attached light.

const Light* osg::LightSource::getLight ( ) const
inline

Get the const attached light.

ReferenceFrame osg::LightSource::getReferenceFrame ( ) const
inline
osg::LightSource::META_Node ( osg  ,
LightSource   
)
void osg::LightSource::setLight ( Light light)

Set the attached light.

void osg::LightSource::setLocalStateSetModes ( StateAttribute::GLModeValue  value = StateAttribute::ON)

Set up the local StateSet.

void osg::LightSource::setReferenceFrame ( ReferenceFrame  rf)

Set the light sources's ReferenceFrame, either to be relative to its parent reference frame, or relative to an absolute coordinate frame. RELATIVE_RF is the default. Note: setting the ReferenceFrame to be ABSOLUTE_RF will also set the CullingActive flag on the light source, and hence all of its parents, to false, thereby disabling culling of it and all its parents. This is necessary to prevent inappropriate culling, but may impact cull times if the absolute light source is deep in the scene graph. It is therefore recommended to only use absolute light source at the top of the scene.

void osg::LightSource::setStateSetModes ( StateSet ,
StateAttribute::GLModeValue   
) const

Set the GLModes on StateSet associated with the LightSource.

virtual void osg::LightSource::setThreadSafeRefUnref ( bool  threadSafe)
virtual

Set whether to use a mutex to ensure ref() and unref() are thread safe.

Reimplemented from osg::Group.
