Detailed Description

Specialisation of HardwareBuffer for a pixel buffer.

The HardwarePixelbuffer abstracts an 1D, 2D or 3D quantity of pixels stored by the rendering API. The buffer can be located on the card or in main memory depending on its usage. One mipmap level of a texture is an example of a HardwarePixelBuffer.

Member Enumeration Documentation

◆ LockOptions

enum Ogre::v1::HardwareBuffer::LockOptions

inherited

Locking options.

Enumerator
HBL_NORMAL	Normal mode, ie allows read/write and contents are preserved.
HBL_DISCARD	Discards the entire buffer while locking; this allows optimisation to be performed because synchronisation issues are relaxed. Only allowed on buffers created with the HBU_DYNAMIC flag.
HBL_READ_ONLY	Lock the buffer for reading only. Not allowed in buffers which are created with HBU_WRITE_ONLY. Mandatory on static buffers, i.e. those created without the HBU_DYNAMIC flag.
HBL_NO_OVERWRITE	As HBL_DISCARD, except the application guarantees not to overwrite any region of the buffer which has already been used in this frame, can allow some optimisation on some APIs.
HBL_WRITE_ONLY	Lock the buffer for writing only.

◆ Usage

enum Ogre::v1::HardwareBuffer::Usage

inherited

Enums describing buffer usage; not mutually exclusive.

Enumerator
HBU_STATIC	Static buffer which the application rarely modifies once created. Modifying the contents of this buffer will involve a performance hit.
HBU_DYNAMIC	Indicates the application would like to modify this buffer with the CPU fairly often. Buffers created with this flag will typically end up in AGP memory rather than video memory.
HBU_WRITE_ONLY	Indicates the application will never read the contents of the buffer back, it will only ever write data. Locking a buffer with this flag will ALWAYS return a pointer to new, blank memory rather than the memory associated with the contents of the buffer; this avoids DMA stalls because you can write to a new memory area while the previous one is being used.
HBU_DISCARDABLE	Indicates that the application will be refilling the contents of the buffer regularly (not just updating, but generating the contents from scratch), and therefore does not mind if the contents of the buffer are lost somehow and need to be recreated. This allows and additional level of optimisation on the buffer. This option only really makes sense when combined with HBU_DYNAMIC_WRITE_ONLY.
HBU_STATIC_WRITE_ONLY	Combination of HBU_STATIC and HBU_WRITE_ONLY.
HBU_DYNAMIC_WRITE_ONLY	Combination of HBU_DYNAMIC and HBU_WRITE_ONLY. If you use this, strongly consider using HBU_DYNAMIC_WRITE_ONLY_DISCARDABLE instead if you update the entire contents of the buffer very regularly.
HBU_DYNAMIC_WRITE_ONLY_DISCARDABLE	Combination of HBU_DYNAMIC, HBU_WRITE_ONLY and HBU_DISCARDABLE.

Member Function Documentation

◆ _updateFromShadow()

virtual void Ogre::v1::HardwareBuffer::_updateFromShadow ( void )

inlinevirtualinherited

Updates the real buffer from the shadow buffer, if required.

Reimplemented in Ogre::v1::D3D11HardwareBuffer, Ogre::v1::GL3PlusHardwareIndexBuffer, Ogre::v1::GL3PlusHardwareVertexBuffer, Ogre::v1::MetalHardwareIndexBuffer, and Ogre::v1::MetalHardwareVertexBuffer.

◆ blit() [1/2]

void Ogre::v1::HardwarePixelBuffer::blit ( const HardwarePixelBufferSharedPtr & src )

Convenience function that blits the entire source pixel buffer to this buffer.

If source and destination dimensions don't match, scaling is done.

Parameters

src	PixelBox containing the source pixels and format in memory

Note: Only call this function when the buffer is unlocked.

◆ blit() [2/2]

virtual void Ogre::v1::HardwarePixelBuffer::blit	(	const HardwarePixelBufferSharedPtr &	src,
		const Box &	srcBox,
		const Box &	dstBox
	)

virtual

Copies a box from another PixelBuffer to a region of the this PixelBuffer.

Parameters

src	Source pixel buffer
srcBox	Box describing the source region in src
dstBox	Box describing the destination region in this buffer

Remarks: The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions.

Note: Only call this function when both buffers are unlocked.

Reimplemented in Ogre::v1::D3D11HardwarePixelBuffer, Ogre::v1::GL3PlusTextureBuffer, Ogre::v1::GLES2TextureBuffer, and Ogre::v1::MetalTextureBuffer.

Parameters

src	PixelBox containing the source pixels and format in memory

Note: Only call this function when the buffer is unlocked.

The source image can be in any pixel format supported by OGRE, and in any size.

Parameters

src	PixelBox containing the source pixels and format in memory
dstBox	Box describing the destination region in this buffer

Remarks: The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions.

virtual void Ogre::v1::HardwareBuffer::copyData	(	HardwareBuffer &	srcBuffer,
		size_t	srcOffset,
		size_t	dstOffset,
		size_t	length,

◆ readData()

virtual

Reads data from the buffer and places it in the memory pointed to by pDest.

Parameters

length	The size of the area to read, in bytes
pDest	The area of memory in which to place the data, must be large enough to accommodate the data!

Implements Ogre::v1::HardwareBuffer.

inlineinherited

Pass true to suppress hardware upload of shadow buffer changes.

◆ unlock()

virtual void Ogre::v1::HardwareBuffer::unlock ( void )

inlinevirtualinherited

Releases the lock on this buffer.

Remarks: Locking and unlocking a buffer can, in some rare circumstances such as switching video modes whilst the buffer is locked, corrupt the contents of a buffer. This is pretty rare, but if it occurs, this method will throw an exception, meaning you must re-upload the data.

: Note that using the 'read' and 'write' forms of updating the buffer does not suffer from this problem, so if you want to be 100% sure your data will not be lost, use the 'read' and 'write' forms instead.

Reimplemented in Ogre::v1::DefaultHardwareVertexBuffer, Ogre::v1::DefaultHardwareIndexBuffer, Ogre::v1::DefaultHardwareUniformBuffer, Ogre::v1::DefaultHardwareCounterBuffer, Ogre::v1::D3D11HardwareIndexBuffer, Ogre::v1::D3D11HardwareUniformBuffer, Ogre::v1::D3D11HardwareVertexBuffer, Ogre::v1::GL3PlusDefaultHardwareVertexBuffer, Ogre::v1::GL3PlusDefaultHardwareIndexBuffer, Ogre::v1::GL3PlusDefaultHardwareUniformBuffer, Ogre::v1::GL3PlusDefaultHardwareCounterBuffer, Ogre::v1::GLES2DefaultHardwareVertexBuffer, Ogre::v1::GLES2DefaultHardwareIndexBuffer, and Ogre::v1::GLES2DefaultHardwareUniformBuffer.

		size_t	length,
		const void *	pSource,
		bool	discardWholeBuffer = `false`
	)

virtual

Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough.

Parameters

offset	The byte offset from the start of the buffer to start writing
length	The size of the data to write to, in bytes
pSource	The source of the data to be written
discardWholeBuffer	If true, this allows the driver to discard the entire buffer when writing, such that DMA stalls can be avoided; use if you can.
