Generic constructor.
- Parameters
-
| initialData | Initial data to populate. If bufferType == BT_IMMUTABLE, can't be null. |
| keepAsShadow | Keeps "intialData" as a shadow copy for reading from CPU without querying the GPU (can be useful for reconstructing buffers on device/context loss or for efficient reading of the data without streaming back from GPU.) |
If keepAsShadow is false, caller is responsible for freeing the data
If keepAsShadow is true, we're responsible for freeing the pointer. We will free the pointer using OGRE_FREE_SIMD( MEMCATEGORY_GEOMETRY ), in which case the pointer must* have been allocated using OGRE_MALLOC_SIMD( MEMCATEGORY_GEOMETRY )
If the constructor throws, then data will NOT be freed, and caller will have to do it.
- See also
- FreeOnDestructor to help you with exceptions and correctly freeing the data.
Must be false if bufferType >= BT_DYNAMIC

Copies the contents of this buffer to another, using GPU -> GPU transfers.
In simple terms it is similar to doing: memcpy( dstBuffer + dstElemStart, this + srcElemStart, srcNumElems );
If dst has a shadow buffer, then src must have it too.
- Parameters
-
| dstBuffer | Buffer to copy to. Must be of type BT_DEFAULT |
| dstElemStart | The offset for dstBuffer. It must be in the unit of measure of dstBuffer. e.g. actual offset in bytes is dstElemStart * dstBuffer->getBytesPerElement() |
| srcElemStart | The offset of this buffer to start from |
| srcNumElems | The number of elements to copy, in units of measure of srcBuffer. When this value is out of bounds, it gets clamped. See remarks. |
