makVrv::DtIndirectVaoManager Class Reference

This class manages the vaos for indirect.

There is only one vao per gl context for indirect, since we use bindless.

It is not buffer specific and just encapsulates a state.

There is only one method of interest: DtIndirectVaoManager::vao()

virtual unsigned int makVrv::DtIndirectVaoManager::vao ( bool  rerecord )

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::recordVAO ( unsigned int  vao )

protectedvirtual

internal method to record a vao

virtual void makVrv::DtIndirectVaoManager::slot_contextAboutToBeDestroyed ( const void *  glContext )

protectedvirtual

slot for when a context is about to be destroyed This is used to delete the vao

virtual void makVrv::DtIndirectVaoManager::deleteVao ( const void *  glContext )
