makVrv::DtIndirectVaoManager Class Reference

'super' class for managing the per gc vao for all indirect geometries There is only one vao per gl conxext, since because of bindless, it is not buffer specific but just encapsulates a state

virtual unsigned int makVrv::DtIndirectVaoManager::getOrCreateAndRecordVAO ( const osg::GraphicsContext *  gc, bool  rerecord = false  )

virtual

method to create and 'record' a vertex array object (VAO) using VAO enables us to combine multiple buffer binds into a single 'command' via 'recording' the VAO

Parameters

rerecord

indicates whether the vao should be re-recorded even if present in our internal map (perhaps because the buffer addresses, etc changed)

virtual void makVrv::DtIndirectVaoManager::releaseGLObjects ( const osg::GraphicsContext *  gc )

virtual

release gl objects

virtual void makVrv::DtIndirectVaoManager::recordVAO ( unsigned int  vao )

protectedvirtual

internal method to record a vao
