| srcBuffer | The buffer from which to read the copied data |
| srcOffset | Offset in the source buffer at which to start reading |
| dstOffset | Offset in the destination buffer to start writing |
| length | Length of the data to copy, in bytes. |

| ID3D11Buffer * Ogre::v1::D3D11HardwareVertexBuffer::getD3DVertexBuffer | ( | ) | const |
Get the D3D-specific vertex buffer.
| bool Ogre::v1::D3D11HardwareVertexBuffer::isLocked | ( | ) | const |
|
overridevirtual |
Lock the buffer for (potentially) reading / writing.
| offset | The byte offset from the start of the buffer to lock |
| length | The size of the area to lock, in bytes |
| options | Locking options |
Reimplemented from Ogre::v1::HardwareBuffer.
|
overridevirtual |
Reads data from the buffer and places it in the memory pointed to by pDest.
| offset | The byte offset from the start of the buffer to read |
| 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.
|
overridevirtual |
Releases the lock on this buffer.
Reimplemented from Ogre::v1::HardwareBuffer.
|
overridevirtual |
Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough.
| 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. |
