Instance Method

newBuffer:type:

Creates a new buffer of the specified length.

Required.

Declaration

- (id<MDLMeshBuffer>)newBuffer:(NSUInteger)length type:(MDLMeshBufferType)type;

Parameters

length

The size, in bytes, of the buffer to create.

type

Use MDLMeshBufferTypeVertex to create a buffer for a mesh’s vertex attribute data, or MDLMeshBufferTypeIndex to create a buffer for a submesh’s index data.

Return Value

A new memory buffer for mesh data.

Discussion

The concrete class implementing this protocol determines the initial contents of the buffer and the memory pool from which the buffer is allocated. To provide a hint that multiple related allocations should share the same pool of memory, use the newBufferFromZone:length:type: method instead.
