virtual AllocResult AllocCacheItem(MeshCacheItem** pdata, MeshCacheItem::MeshType meshType, MeshCacheItem::MeshBaseContent & mc, UPInt vertexBufferSize, unsigned vertexCount, unsigned indexCount, bool waitForCache, const VertexFormat* pDestFormat) = 0;
AllocCacheItem allocates back-end specific MeshCacheItem and its buffers. This method is used for PrepareComplexMesh, but also potentially by internal PreparePrimitive.

MeshCacheItem** pdata |
Pointer to the mesh data cached in the buffer// pointer to the start of the buffer holding the cached mesh data. |
|
MeshCacheItem::MeshType meshType |
The type of the mesh to be allocated (regular or complex). |
|
MeshCacheItem::MeshBaseContent & mc |
The contents of the mesh. |
|
UPInt vertexBufferSize |
The size of the vertex buffer. |
|
unsigned vertexCount |
The number of vertices in the buffer. |
|
unsigned indexCount |
The indices into the vertex buffer. |

const VertexFormat* pDestFormat |
The format of the generated meshes. |
Returns the flag indicating success/failure in allocating the meshes.
