Override HardwareBuffer to turn off all shadowing.
Reimplemented from Ogre::v1::HardwareBuffer.
|
virtual |
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.

Override HardwareBuffer to turn off all shadowing.
Reimplemented from Ogre::v1::HardwareBuffer.
|
virtual |
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. |
