Points

Description

A type for points (as distinct from vectors).

Synopsis

Points

newtype Point v Source

Point is a newtype wrapper around vectors that we wish to treat as points, so we don't get them mixed up. The distinction is important: translations affect points, but leave vectors unchanged. Points are instances of the AffineSpace class from Data.AffineSpace.
