mbb

Arguments

:: Double

x - coordinate of first point

-> Double

y - coordinate of first point

-> Double

x - coordinate of second point

-> Double

x - coordinate of second point

-> MBB

created a minimal bounding box (or a rectangle) The first point must be smaller, than the second one. This is unchecked.

area :: MBB -> Double

calculates the area of the rect

containsMBB :: MBB -> MBB -> Bool

returns True, when the first mbb contains the second

unionMBB :: MBB -> MBB -> MBB

unifies two MBBs into one

unionsMBB :: [MBB] -> MBB

internal only.

intersectMBB :: MBB -> MBB -> Maybe MBB

returns the intersection of both mbbs. Returns Nothing, if they don't intersect.

isValidMBB :: MBB -> Bool

the property, that a MBB must hold

isPointMBB :: MBB -> Bool
