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. Definition at line 69 of file OgreHardwareBuffer.h.

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.
