◆ createVertexBuffers()

void Ogre::GL3PlusMultiSourceVertexBufferPool::createVertexBuffers ( VertexBufferPackedVec outVertexBuffers,
size_t  numVertices,
void *const initialData,
bool  keepAsShadow 
)
virtual

Creates a vertex buffer based on the given parameters.

Behind the scenes, the vertex buffer is part of much larger vertex buffer, in order to reduce bindings at runtime.

Parameters
outVertexBuffers[out] A list of the generated vertex buffers, one per buffer source in mVertexElementsPerSource. WARNING: Can be empty if the pool is out of memory or too fragmented to honour this request, in which case you need to use another pool (or free some memory from this pool).
numVerticesThe number of vertices for these vertex buffer.
initialDataInitial data the buffer will hold upon creation. Can be null (i.e. you plan to upload later). Cannot be null when bufferType is BT_IMMUTABLE. Must have enough room to prevent an overflow. If non-null, the buffer must hold enough data for each vertex buffers. E.g. If mVertexElementsPerSource.size() == 3 then this is valid: initialData = 0; This is also valid: initialData[0] = buffer[numVertices * sumOfBytes(mVertexElementsPerSource[0])]; initialData[1] = 0; //Unless bufferType == BT_IMMUTABLE initialData[2] = buffer[numVertices * sumOfBytes(mVertexElementsPerSource[2])];

This is invalid: initialData[0] = whatever; initialData[1] = out of bounds;

Parameters
keepAsShadowWhether to keep the pointer "initialData" as a shadow copy of the contents. @See BufferPacked::BufferPacked regarding on who is responsible for freeing this pointer and what happens if an exception was raised.
Returns
The desired vertex buffer pointer

Implements Ogre::MultiSourceVertexBufferPool.

◆ destroyVertexBuffers()

void Ogre::MultiSourceVertexBufferPool::destroyVertexBuffers ( VertexBufferPackedVec inOutVertexBuffers)
inherited

Destroys all the buffers returned from a call to createVertexBuffers.

All the returned buffers from that call must be supplied. Not one more, not one less. They can be in any order, though.

Parameters
inOutVertexBuffers[in] [out] In: The list of buffers that was returned by createVertexBuffers. Can be sorted in any order Out: Cleared list.
