Member Function Documentation

◆ _update()

virtual void Ogre::GLES2VaoManager::_update ( )

virtual

Reimplemented from Ogre::VaoManager.

◆ bindDrawId()

void Ogre::GLES2VaoManager::bindDrawId ( )

Binds the Draw ID to the currently bound vertex array object.

◆ createAsyncTicket()

virtual AsyncTicketPtr Ogre::GLES2VaoManager::createAsyncTicket	(	BufferPacked *	creator,
		StagingBuffer *	stagingBuffer,
		size_t	elementStart,
		size_t	elementCount
	)

virtual

Implements Ogre::VaoManager.

◆ createStagingBuffer()

virtual StagingBuffer * Ogre::GLES2VaoManager::createStagingBuffer	(	size_t	sizeBytes,
		bool	forUpload
	)

virtual

Creates a new staging buffer and adds it to the pool.

See also: getStagingBuffer.

Remarks: The returned buffer starts with a reference count of 1. You should decrease it when you're done using it.

Implements Ogre::VaoManager.

static

◆ getMaxVertexAttribs()

◆ isFrameFinished()

virtual bool Ogre::GLES2VaoManager::isFrameFinished ( uint32 frameCount )

virtual

See VaoManager::isFrameFinished.

Implements Ogre::VaoManager.

◆ mergeContiguousBlocks()

static void Ogre::GLES2VaoManager::mergeContiguousBlocks	(	BlockVec::iterator	blockToMerge,

◆ supportsArbBufferStorage()

bool Ogre::GLES2VaoManager::supportsArbBufferStorage ( ) const

inline

◆ waitFor()

static GLsync Ogre::GLES2VaoManager::waitFor ( GLsync fenceName )

static

Will stall undefinitely until GPU finishes (signals the sync object).

Parameters

fenceName Sync object to wait for. Will be deleted on success. On failure, throws an exception and fenceName will not be deleted.

Returns: Null ptr on success. Should throw on failure, but if this function for some strange reason doesn't throw, it is programmed to return 'fenceName'

◆ waitForSpecificFrameToFinish()

virtual void Ogre::GLES2VaoManager::waitForSpecificFrameToFinish ( uint32 frameCount )

virtual

See VaoManager::waitForSpecificFrameToFinish.

Implements Ogre::VaoManager.

◆ waitForTailFrameToFinish()

virtual uint8 Ogre::GLES2VaoManager::waitForTailFrameToFinish ( )

virtual

See VaoManager::waitForTailFrameToFinish.
