Detailed Description

Class that encapsulates an GL context.

(IE a window/pbuffer). This is a virtual base class which should be implemented in a GLSupport. This object can also be used to cache renderstate if we decide to do so in the future.

◆ ~GLContext()

Member Function Documentation

◆ setCurrent()

virtual void Ogre::GLContext::setCurrent ( )
pure virtual

Enable the context.

All subsequent rendering commands will go here.

◆ endCurrent()

virtual void Ogre::GLContext::endCurrent ( )
pure virtual

This is called before another context is made current.

By default, nothing is done here.

◆ getInitialized()

bool Ogre::GLContext::getInitialized ( )
inline

◆ setInitialized()

void Ogre::GLContext::setInitialized ( )
inline

◆ clone()

virtual GLContext* Ogre::GLContext::clone ( ) const
pure virtual

Create a new context based on the same window/pbuffer as this context - mostly useful for additional threads.

Note
The caller is responsible for deleting the returned context.

◆ releaseContext()

virtual void Ogre::GLContext::releaseContext ( )
inlinevirtual

Release the render context.

◆ createOrRetrieveStateCacheManager()

template<class StateCacheManager >
StateCacheManager* Ogre::GLContext::createOrRetrieveStateCacheManager ( )
inline

Get the state cache manager, creating it on demand.

◆ _getVaoDeferredForDestruction()

std::vector<uint32>& Ogre::GLContext::_getVaoDeferredForDestruction ( )
inline

VAOs deferred for destruction in proper GL context.

◆ _getFboDeferredForDestruction()

std::vector<uint32>& Ogre::GLContext::_getFboDeferredForDestruction ( )
inline

FBOs deferred for destruction in proper GL context.
