Arc
Simple constructor.If either
lower
is equals toupper
or the interval exceeds \( 2 \pi \), the arc is considered to be the full circle and its initial defining boundaries will be forgotten.lower
is not allowed to be greater thanupper
(an exception is thrown in this case).lower
will be canonicalized between 0 and \( 2 \pi \), and upper shifted accordingly, so thegetInf()
andgetSup()
may not return the value used at instance construction.- Parameters:
lower
- lower angular bound of the arcupper
- upper angular bound of the arctolerance
- tolerance below which angles are considered identical- Throws:
MathIllegalArgumentException
- if lower is greater than upper or tolerance is smaller thanSphere1D.SMALLEST_TOLERANCE

Method Details
-
getInf
public double getInf()Get the lower angular bound of the arc.- Returns:
- lower angular bound of the arc, always between 0 and \( 2 \pi \)
-
getSup
public double getSup()Get the upper angular bound of the arc. -
getSize
public double getSize()Get the angular size of the arc.- Returns:
- angular size of the arc
-
getBarycenter
public double getBarycenter()Get the barycenter of the arc.- Returns:
- barycenter of the arc
-
getTolerance
public double getTolerance()Get the tolerance below which angles are considered identical.- Returns:
- tolerance below which angles are considered identical
-
checkPoint
Check a point with respect to the arc.- Parameters:
point
- point to check- Returns:
- a code representing the point status: either
Region.Location.INSIDE
,Region.Location.OUTSIDE
orRegion.Location.BOUNDARY
-
getOffset
public double getOffset(double point) Get the distance (arc length) from a point to the edge of the arc.This method does not use
