Instances
class AffineTransform a whereSource
($*) :: AffineTransform a => Transform -> a -> aSource
Operator for applying a transformation.
lineEquation :: Line -> (Double, Double, Double)Source
Return the parameters (a, b, c) for the normalised equation
of the line: a*x + b*y + c = 0.
lineDistance :: Line -> Point -> DoubleSource
Return the the distance from a point to the line.
normVector :: Point -> PointSource
The unit vector with the same direction.
vectorCross :: Point -> Point -> DoubleSource
Cross product of two vectors.
vectorDistance :: Point -> Point -> DoubleSource
Distance between two vectors.
