# vertexBuffers The array of buffers that provide vertex data for the mesh. ``` var vertexBuffers: [any MDLMeshBuffer] { get set } ``` ## Discussion A mesh contains vertex data organized in one of two designs: as a *structure of arrays* or as an *array of structures*. In a structure of arrays, the mesh contains multiple vertex buffers, each of which provides data for a different vertex attribute, and a single vertex is the union of data from the same index in each of the separate buffers. In an array of structures, the mesh contains a single vertex buffer, and each index in the vertex buffer contains data for all vertex attributes. Use the [`vertexDescriptor`](/documentation/ModelIO/MDLMesh/vertexDescriptor) property to determine the structure of the mesh’s vertex data. --- Copyright © 2026 Apple Inc.
