Member Function Documentation

virtual void Ogre::HardwareBufferManager::_forceReleaseBufferCopies ( const HardwareVertexBufferSharedPtr & sourceBuffer ) [virtual, inherited]

Internal method that forces the release of copies of a given buffer.

Remarks:: This usually means that the buffer which the copies are based on has been changed in some fundamental way, and the owner of the original wishes to make that known so that new copies will reflect the changes.

Parameters:

sourceBuffer The source buffer as a shared pointer. Any buffer copies created from the source buffer are deleted.

Reimplemented from Ogre::HardwareBufferManagerBase.

Definition at line 536 of file OgreHardwareBufferManager.h.

virtual void Ogre::HardwareBufferManager::_forceReleaseBufferCopies ( HardwareVertexBuffer * sourceBuffer ) [virtual, inherited]

Internal method that forces the release of copies of a given buffer.

Remarks:: This usually means that the buffer which the copies are based on has been changed in some fundamental way, and the owner of the original wishes to make that known so that new copies will reflect the changes.

Parameters:

sourceBuffer The source buffer as a shared pointer. Any buffer copies created from the source buffer are deleted.

Reimplemented from Ogre::HardwareBufferManagerBase.

Definition at line 542 of file OgreHardwareBufferManager.h.

virtual void Ogre::HardwareBufferManager::_freeUnusedBufferCopies ( void ) [virtual, inherited]

Free all unused vertex buffer copies.

Remarks:: This method free all temporary vertex buffers that not in used. In normally, temporary vertex buffers are subsequently stored and can be made available for other purposes later without incurring the cost of construction / destruction. But in some cases you want to free them to save hardware memory (e.g. application was runs in a long time, you might free temporary buffers periodically to avoid memory overload).

virtual void Ogre::HardwareBufferManager::_releaseBufferCopies ( bool forceFreeUnused = false ) [virtual, inherited]

Internal method for releasing all temporary buffers which have been allocated using BLT_AUTOMATIC_RELEASE; is called by OGRE.

Parameters:

forceFreeUnused If true, free all unused temporary buffers. If false, auto detect and free all unused temporary buffers based on temporary buffers utilization.

Reimplemented from Ogre::HardwareBufferManagerBase.

Definition at line 531 of file OgreHardwareBufferManager.h.

void* Ogre::GL3PlusHardwareBufferManager::allocateScratch ( uint32 size )

Allocator method to allow us to use a pool of memory as a scratch area for hardware buffers.

This is because glMapBuffer is incredibly inefficient, seemingly no matter what options we give it. So for the period of lock/unlock, we will instead allocate a section of a local memory pool, and use glBufferSubDataARB / glGetBufferSubDataARB instead.

virtual HardwareVertexBufferSharedPtr Ogre::HardwareBufferManager::allocateVertexBufferCopy	(	const HardwareVertexBufferSharedPtr &	sourceBuffer,
		BufferLicenseType	licenseType,
		HardwareBufferLicensee *	licensee,
		bool	copyData = `false`
	)		`[virtual, inherited]`

Allocates a copy of a given vertex buffer.

Remarks:: This method allocates a temporary copy of an existing vertex buffer. This buffer is subsequently stored and can be made available for other purposes later without incurring the cost of construction / destruction.

Parameters:

sourceBuffer	The source buffer to use as a copy.
licenseType	The type of license required on this buffer - automatic release causes this class to release licenses every frame so that they can be reallocated anew.
licensee	Pointer back to the class requesting the copy, which must implement HardwareBufferLicense in order to be notified when the license expires.
copyData	If `true`, the current data is copied as well as the structure of the buffer/

HardwareCounterBufferSharedPtr Ogre::HardwareBufferManager::createCounterBuffer	(	size_t	sizeBytes,
		HardwareBuffer::Usage	usage,
		bool	useShadowBuffer,
		const String &	name = `""`
	)		`[virtual, inherited]`

Create counter buffer.

The update shall be triggered by GpuProgramParameters, if is dirty

Implements Ogre::HardwareBufferManagerBase.

Definition at line 469 of file OgreHardwareBufferManager.h.

HardwareIndexBufferSharedPtr Ogre::HardwareBufferManager::createIndexBuffer	(	HardwareIndexBuffer::IndexType	itype,
		size_t	numIndexes,
		HardwareBuffer::Usage	usage,
		bool	useShadowBuffer = `false`
	)		`[virtual, inherited]`

Create a hardware index buffer.

Remarks:: Note that because buffers can be shared, they are reference counted so you do not need to worry about destroying them this will be done automatically.

Parameters:

itype	The type in index, either 16- or 32-bit, depending on how many vertices you need to be able to address
numIndexes	The number of indexes in the buffer
usage	One or more members of the HardwareBuffer::Usage enumeration.
useShadowBuffer	If set to `true`, this buffer will be 'shadowed' by one stored in system memory rather than GPU or AGP memory. You should set this flag if you intend to read data back from the index buffer, because reading data from a buffer in the GPU or AGP memory is very expensive, and is in fact impossible if you specify HBU_WRITE_ONLY for the main buffer. If you use this option, all reads and writes will be done to the shadow buffer, and the shadow buffer will be synchronised with the real buffer at an appropriate time.

Implements Ogre::HardwareBufferManagerBase.

Definition at line 448 of file OgreHardwareBufferManager.h.

RenderToVertexBufferSharedPtr Ogre::HardwareBufferManager::createRenderToVertexBuffer ( void ) [virtual, inherited]

Create a render to vertex buffer.

Remarks:: The parameters (such as vertex size etc) are determined later and are allocated when needed.

Implements Ogre::HardwareBufferManagerBase.

Definition at line 455 of file OgreHardwareBufferManager.h.

HardwareUniformBufferSharedPtr Ogre::HardwareBufferManager::createUniformBuffer	(	size_t	sizeBytes,
		HardwareBuffer::Usage	usage,
		bool	useShadowBuffer,
		const String &	name = `""`
	)		`[virtual, inherited]`

Create uniform buffer.

This type of buffer allows the upload of shader constants once, and sharing between shader stages or even shaders from another materials. The update shall be triggered by GpuProgramParameters, if is dirty

Implements Ogre::HardwareBufferManagerBase.

Reimplemented in Ogre::GLESDefaultHardwareBufferManager.

Definition at line 462 of file OgreHardwareBufferManager.h.

HardwareVertexBufferSharedPtr Ogre::HardwareBufferManager::createVertexBuffer	(	size_t	vertexSize,
		size_t	numVerts,
		HardwareBuffer::Usage	usage,
		bool	useShadowBuffer = `false`
	)		`[virtual, inherited]`

Create a hardware vertex buffer.

Remarks:: This method creates a new vertex buffer; this will act as a source of geometry data for rendering objects. Note that because the meaning of the contents of the vertex buffer depends on the usage, this method does not specify a vertex format; the user of this buffer can actually insert whatever data they wish, in any format. However, in order to use this with a RenderOperation, the data in this vertex buffer will have to be associated with a semantic element of the rendering pipeline, e.g. a position, or texture coordinates. This is done using the VertexDeclaration class, which itself contains VertexElement structures referring to the source data.; Note that because vertex buffers can be shared, they are reference counted so you do not need to worry about destroying themm this will be done automatically.

Parameters:

vertexSize	The size in bytes of each vertex in this buffer; you must calculate this based on the kind of data you expect to populate this buffer with.
numVerts	The number of vertices in this buffer.
usage	One or more members of the HardwareBuffer::Usage enumeration; you are strongly advised to use HBU_STATIC_WRITE_ONLY wherever possible, if you need to update regularly, consider HBU_DYNAMIC_WRITE_ONLY and useShadowBuffer=true.
useShadowBuffer	If set to `true`, this buffer will be 'shadowed' by one stored in system memory rather than GPU or AGP memory. You should set this flag if you intend to read data back from the vertex buffer, because reading data from a buffer in the GPU or AGP memory is very expensive, and is in fact impossible if you specify HBU_WRITE_ONLY for the main buffer. If you use this option, all reads and writes will be done to the shadow buffer, and the shadow buffer will be synchronised with the real buffer at an appropriate time.

This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.
