nvector :: Double -> Double -> Double -> NVector Source #

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

cross :: NVector -> NVector -> NVector Source #

Computes the cross product of the two given NVectors.

dot :: NVector -> NVector -> Double Source #

Computes the dot product of the two given NVectors.

norm :: NVector -> Double Source #

Computes the norm of the given NVector.

scale :: NVector -> Double -> NVector Source #

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

unit :: NVector -> NVector Source #

Normalises the given NVector.

zero :: NVector Source #

0, 0, 0
- not a valid NVector, but can be used as the identity value during reduction.
