Class

MDLMeshBufferMap

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

Declaration

class MDLMeshBufferMap : NSObject

Overview

Typically, you do not create MDLMeshBufferMap objects directly. Instead, you use classes supporting the MDLMeshBuffer protocol to manage mesh buffer memory shared with a rendering technology—for example, the MTKMeshBuffer class for rendering with Metal. A mesh buffer object vends a MDLMeshBufferMap objects when you use the map() method to gain temporary access to the shared memory.

Topics

Creating a Buffer Map

init(bytes: UnsafeMutableRawPointer, deallocator: (() -> Void)?)

Initializes a buffer map object to manage access to the specified memory.

Accessing Buffer Data

var bytes: UnsafeMutableRawPointer

A pointer to the mutable memory managed by the buffer map.

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

A description of the structure, format, and layout for vertex data buffers associated with a mesh.
