Constructors

MDLAsset()

Default constructor, initializes a new instance of this class.

MDLAsset(IMDLMeshBufferAllocator)

Creates a new Model IO asset by using the provided bufferAllocator.

MDLAsset(IntPtr)

A constructor used when creating managed representations of unmanaged objects; Called by the runtime.

MDLAsset(NSObjectFlag)

Constructor to call on derived classes to skip initialization and merely allocate the object.

MDLAsset(NSUrl)

Creates a new MDLAsset by loading the file at the specified URL.

MDLAsset(NSUrl, MDLVertexDescriptor, IMDLMeshBufferAllocator)

Creates a new MDLAsset by loading the file at the specified URL into the buffers provided by the buffer allocator, and formatting the data in memory as described by the vertex descriptor.

MDLAsset(NSUrl, MDLVertexDescriptor, IMDLMeshBufferAllocator, Boolean, NSError)

Creates a new MDLAsset by loading the file at the specified URL into the buffers provided by the buffer allocator, and formatting the data in memory as described by the vertex descriptor.
