Instances

Eq NVector

Defined in Data.Geo.Jord.NVector

Methods

(==) :: NVector -> NVector -> Bool

(/=) :: NVector -> NVector -> Bool

Show NVector

Defined in Data.Geo.Jord.NVector

Methods

showsPrec :: Int -> NVector -> ShowS

show :: NVector -> String

showList :: [NVector] -> ShowS

Quantity NVector

Add and subtract NVectors.

Defined in Data.Geo.Jord.NVector

Methods

add :: NVector -> NVector -> NVector

sub :: NVector -> NVector -> NVector

Position NVector

Identity.

Defined in Data.Geo.Jord.Position

Methods

fromNVector :: NVector -> NVector

toNVector :: NVector -> NVector

nvector :: Double -> Double -> Double -> NVector

Smart NVector constructor. The returned NVector is a unit vector.

cross :: NVector -> NVector -> NVector

Computes the cross product of the two given NVectors.

dot :: NVector -> NVector -> Double

Computes the dot product of the two given NVectors.

norm :: NVector -> Double

Computes the norm of the given NVector.

scale :: NVector -> Double -> NVector

Multiplies each component of the given NVector by the given value.

unit :: NVector -> NVector

Normalises the given NVector.

zero :: NVector

0, 0, 0

- not a valid NVector, but can be used as the identity value during reduction.
