A chebychev distance measure, based on the maximum of the absolute distances across the first two dimensions.
A chebychev distance measure, based on the maximum of the absolute distances across the first two dimensions. The 3rd dimension is ignored!
A measure that uses the euclidean squared distance which is faster than the euclidean distance as the square root does not need to be taken.
An 'inverted' chebychev distance measure, based on the *minimum* of the absolute distances across the first two dimensions.
An 'inverted' chebychev distance measure, based on the *minimum* of the absolute distances across the first two dimensions. The 3rd dimension is ignored! This is, strictly speaking, only a semi metric.
