A standard implementation of the MDLMeshBufferZone protocol.


class MDLMeshBufferZoneDefault : NSObject


Model I/O uses zones to ensure that related allocations—such as the multiple vertex and index buffers associated with a MDLMesh object—use contiguous blocks of memory for optimal performance. When working with a MDLMeshBufferAllocator object that does not implement its own zone management, Model I/O uses this zone class.This class declares no methods or properties of its own. For the key functionality of all mesh buffer zone objects, see MDLMeshBufferZone.

A memory buffer that stores vertex or index data for a Model I/O mesh.

class MDLMeshBufferDataAllocator

A basic allocator implementation that allocates from main memory using data objects.

class MDLMeshBufferMap

An object that manages access to a memory buffer used for the data storage of a Model I/O mesh.

protocol MDLMeshBufferZone

The general interface for logical pools of memory used in allocation of related mesh data buffers.

class MDLVertexAttribute

class MDLVertexAttributeData

An object that provides convenience access to vertex data for a specific vertex attribute of a mesh.

class MDLVertexBufferLayout

A MDLVertexBufferLayout object describes layout information for a vertex buffer in a MDLMesh object. A collection of vertex layer objects, vertex attribute objects, and additional information forms a MDLVertexDescriptor object, which completely describes the layout of vertex buffers for a mesh.

class MDLVertexDescriptor
