MDLMeshBufferZone
The general interface for logical pools of memory used in allocation of related mesh data buffers.
Declaration
protocol MDLMeshBufferZone : NSObjectProtocolOverview
The concrete type of a zone is often private—you obtain zones by creating them from a MDLMeshBufferAllocator object, then use zones with allocator methods such as newBuffer(from:data:type:) when you need to ensure that related buffers are allocated together.
