Detailed Description

An arc (a segment of a circle) specified by a center point, a radius and a starting and ending angle.

Note: : the starting and ending angles should be in the range [-M_PI, M_PI] or intersection functions will not work as expected. In addition, start should be less than or equal to end

Constructor & Destructor Documentation

inline

Initialize an arc with a given center, radius, and starting and ending angle (in radians).

Parameters

center	the center point of the characteristic circle
radius	the radius of the characteristic circle
start	the starting angle in radians in the range [-M_PI, M_PI]
end	the ending angle in radians in the range [-M_PI, M_PI]
