makVrv::DtIndirectTextureLoaderNode Class Reference

node for processing textures needed for indirect geometries this allows for textures to be uploaded to the GPU before the tile has paged in so that there are not holes/gray tiles poping in

Constructor & Destructor Documentation

makVrv::DtIndirectTextureLoaderNode::DtIndirectTextureLoaderNode ( DtDe &  de )

protected

Constructor.

virtual makVrv::DtIndirectTextureLoaderNode::~DtIndirectTextureLoaderNode ( )

virtual

Destructor - clears the list of registrars.

makVrv::DtIndirectTextureLoaderNode::DtIndirectTextureLoaderNode ( const DtIndirectTextureLoaderNode &  other )

delete

Copy Constructor not implemented – Copy Not Allowed.

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 notifies 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 registrar list notifies 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 registrar 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
