linear_to_coordinates()

std::vector< uint64_t > MayaFlux::Kakshya::linear_to_coordinates	(	uint64_t	index,
		const std::vector< DataDimension > &	dimensions
	)

Convert a linear index to N-dimensional coordinates for interleaved data.

Parameters

index	Linear index into the underlying data storage.
dimensions	Dimension descriptors (size/stride/role).

Returns

N-dimensional coordinates.

Note

Only works with interleaved organization strategy. For planar data, coordinates map directly to {channel_vector_index, frame_index}.
