Initializer

init(vertexDescriptor:)

Creates a new vertex descriptor by performing a deep copy of the specified vertex descriptor.

Declaration

init(vertexDescriptor: MDLVertexDescriptor)

Parameters

vertexDescriptor

The vertex descriptor from which to copy information.

Return Value

A new vertex descriptor that is an indpendent copy of the specified vertex descriptor.

Discussion

A vertex descriptor does not own vertex data—vertex data belongs to the vertexBuffers property of the mesh that owns a vertex descriptor—so this method does not copy vertex data. A call to the copy() or copy(with:) method uses this initializer to produce a fully independent copy of the original instance.
