void makVrv::DtIndirectTextureLoaderNode::accept

(

osg::NodeVisitor &

nv

)

called when the scene is traversed, only does stuff in the cull visitor called in the main thread every frame - uses mutex for thread safe access to the registrar

virtual void makVrv::DtIndirectTextureLoaderNode::drawImplementation ( osg::RenderInfo &  renderInfo ) const

virtual

called during the draw stage.

Doesn't draw anything, just uploads textures to the GPU called in the main thread every frame - uses mutex for thread safe access to the registrar notifys the condition when a registrar finishes and the list of registrars is changing.

virtual void makVrv::DtIndirectTextureLoaderNode::addIndirectRegistrarToProcess ( DtIndirectGeometryRegistrar *  registrar )

virtual

add an indirect registrar to the list of registrars to process called in a background paging thread - uses mutex for thread safe access of registrar list

virtual void makVrv::DtIndirectTextureLoaderNode::removeIndirectRegistrarToProcess ( DtIndirectGeometryRegistrar *  registrar )

virtual

remove an indirect registrar from the list of registrars to process called in the main thread - uses mutex for thread safe access of registar list notifys the condition since the list of registrars is changing.

virtual bool makVrv::DtIndirectTextureLoaderNode::containsIndirectRegistrarToProcess ( DtIndirectGeometryRegistrar *  registrar, bool  blocking = true  )

virtual

check to see if an indirect registrar is in the list of registrars to process called in a background paging thread - uses mutex for thread safe access of registar list if blocking is true then it will use a wait condition to wait for a registrar to be removed also checks after a second to see if the database pager has been stopped.

virtual void makVrv::DtIndirectTextureLoaderNode::clearIndirectRegistrarsToProcess ( bool  lastCall = false )

virtual

clear the list of indirect registrars to process
