Directions in 3D
A Direction
represents directions in R3. The constructor is
not exported; Direction
s can be used with fromDirection
and the
lenses provided by its instances.
direction :: R3 -> Direction Source
direction v
is the direction in which v
points. Returns an
unspecified value when given the zero vector as input.
fromDirection :: Direction -> R3 Source
fromDirection d
is the unit vector in the direction d
.
angleBetweenDirs :: Direction -> Direction -> Angle Source
compute the positive angle between the two directions in their common plane
other coördinate systems
class Spherical t where Source
Types which can be expressed in spherical 3D coordinates, as a triple (r,θ,φ), where θ is rotation about the Z axis, and φ is the angle from the Z axis.
class Cylindrical t where Source
Types which can be expressed in cylindrical 3D coordinates.
