A type for points (as distinct from vectors).
newtype Point v
Point is a newtype wrapper around vectors used to represent
points, so we don't get them mixed up. The distinction between
vectors and points is important: translations affect points, but
leave vectors unchanged. Points are instances of the
AffineSpace class from Data.AffineSpace.
|Eq v => Eq (Point v)|
|(Typeable (Point v), Data v) => Data (Point v)|
|(Eq (Point v), Ord v) => Ord (Point v)|
|Read v => Read (Point v)|
|Show v => Show (Point v)|
|(AdditiveGroup (Diff (Point v)), AdditiveGroup v) => AffineSpace (Point v)|
|(VectorSpace (V (Point v)), VectorSpace v) => HasOrigin (Point v)|
|(HasLinearMap (V (Point v)), HasLinearMap v) => Transformable (Point v)|
|(Ord (Scalar (V (Point v))), VectorSpace (V (Point v)), Ord (Scalar v), VectorSpace v) => Traced (Point v)|
The trace of a single point is the empty trace, i.e. the one which returns positive infinity for every query. Arguably it should return a finite distance for vectors aimed directly at the given point and infinity for everything else, but due to floating-point inaccuracy this is problematic. Note that the envelope for a single point is *not* the empty envelope (see Diagrams.Core.Envelope).
|(InnerSpace (V (Point v)), OrderedField (Scalar (V (Point v))), OrderedField (Scalar v), InnerSpace v) => Enveloped (Point v)|
