Public Member Functions

 D3D9HardwarePixelBuffer (HardwareBuffer::Usage usage)
void bind (IDirect3DDevice9 *dev, IDirect3DSurface9 *mSurface)
 Call this to associate a D3D surface or volume with this pixel buffer.

void bind (IDirect3DDevice9 *dev, IDirect3DVolume9 *mVolume)
void blit (HardwarePixelBuffer *src, const Image::Box &srcBox, const Image::Box &dstBox)
 
Parameters:
dst Source pixel buffer
srcBox Image::Box describing the source region in src
dstBox Image::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 done in software for some render systems, thus for realtime usage it is recommended to pass the source image in the right dimensions.
Note:
Only call this function when both buffers are unlocked.


void blitFromMemory (const PixelBox &src, const Image::Box &dstBox)
 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 Image::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 done in software for some render systems, so for realtime usage it is recommended to pass the source image in the right dimensions.

Member Enumeration Documentation

enum Ogre::HardwareBuffer::LockOptions [inherited]
 

Locking options.

Enumeration values:
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 statuc buffers, ie those created without the HBU_DYNAMIC flag.

HBL_NO_OVERWRITE  As HBL_NORMAL, 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.

Definition at line 111 of file OgreHardwareBuffer.h.

enum Ogre::HardwareBuffer::Usage [inherited]
 

Enums describing buffer usage; not mutually exclusive.

Enumeration values:
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.

virtual void Ogre::HardwareBuffer::unlock (  void   )  [virtual, inherited]
 

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.

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.
