Method Detail

arrayForCommandBufferArrayDescriptorKernel

MPSNDArray arrayForCommandBufferArrayDescriptorKernel(MTLCommandBuffer cmdBuf,
                                                      MPSNDArrayDescriptor descriptor,
                                                      MPSKernel kernel)

Create a new MPSNDArray

See class description for sample implementation

Parameters:

cmdBuf - The MTLCommandBuffer on which the array will be initialized. cmdBuf.device encodes the MTLDevice.

descriptor - A MPSNDArrayDescriptor containing the array parameters to use. This format is the result of your MPSPadding policy.

kernel - The kernel that will overwrite the array returned by the filter. Note that the MPS implementations of this protocol don't need this field. It is provided for your convenience.

Returns:

A valid MPSNDArray or MPSTemporaryNDArray. It will be automatically released when the command buffer completes.
