Instance Method

setVertexBuffer:offset:atIndex:

Sets a buffer for the vertex function.

Required.

Declaration

- (void)setVertexBuffer:(id<MTLBuffer>)buffer offset:(NSUInteger)offset atIndex:(NSUInteger)index;

Parameters

buffer

The buffer to set in the buffer argument table.

offset

Where the data begins, in bytes, from the start of the buffer.

index

An index in the buffer argument table.

Discussion

For buffers in the device address space, align the offset to the data type consumed by the vertex function (which is always less than or equal to 16 bytes).

For buffers in the constant address space, align the offset to 256 bytes in macOS. In iOS, align the offset to the maximum of either the data type consumed by the vertex function, or 4 bytes. A 16-byte alignment is safe in iOS if you don't need to consider the data type.
