geometry

Library for (numerical) geometry.

Functions

antipode(circle, point)
bisect(g)	Split object (Segment or CircularArc) into two equal halves.
bisector(s)	Return the bisector line of the segment
bounding_box(a)
circle_through_points(A, B, C)	Return a circle through points A, B, and C.
inverse_point_through_circle(circle, point)	Perform inverse geometry transformation on a given point with respect to a circle.
is_angle_between(theta1, theta2, theta3)	Check if angle theta2 is between angles theta1 and theta3 (modulo 2*pi).
middle(g)	Returns geometric center of a segment or arc
perpendicular_arc(circle, circle1, circle2)	Return the perpendicular circular arc through the circle that starts and ends at the intersection of circle and circle1 and circle2, respectively.
perpendicular_arc_through_point(circle, ...)	Return the arc that is: - perpendicular to the circle at circle_point - starts at the circle point and goes through the point - (if the point lies on the circle, the arc is perpendicular also at point.
perpendicular_line(l, p)	Return a line that is perpendicular to the other line.
split(g, point)	Split arc/segment g at point (that lies on the arc/segment)
tangent_line(c, p)	Return tangent line assuming point lies on circle, otherwise returns line perpendicular to the radius through the center and p.
weighted_circle_center_mean(circle1, circle2)	Compute a weighted mean, so that the intersection of cicles are scaled proportinately so they meet.
