Functions

• angle
  Angle of the direction vector described by p0 to p1.
• angle_from_bulge
  Returns the arc sweep angle for the given bulge.
• angle_is_between
  Same as angle_is_between_eps using default epsilon.
• angle_is_between_eps
  Tests if test_angle is between a start_angle and end_angle.
• angle_is_within_sweep
  Same as angle_is_within_sweep_eps using default epsilon.
• angle_is_within_sweep_eps
  Tests if test_angle is within the sweep_angle starting at start_angle.
• bulge_from_angle
  Returns the bulge for the given arc sweep_angle.
• circle_circle_intr
  Finds the intersects between two circles defined by the radius and center.
• delta_angle
  Returns the smaller difference between two angles.
• delta_angle_signed
  Returns the smaller difference between two angles and applies the sign given.
• dist_squared
  Distance squared between the points p0 and p1.
• is_left
  Returns true if point is left of a direction vector.
• is_left_or_coincident
  Same as is_left_or_coincident_eps using default epsilon.
• is_left_or_coincident_eps
  Returns true if point is left of a direction vector with fuzzy inclusion.
• is_left_or_equal
  Same as is_left but uses <= operator rather than < for boundary inclusion.
• is_right_or_coincident
  Same as is_right_or_coincident_eps using default epsilon.
• is_right_or_coincident_eps
  Returns true if point is right of a direction vector with fuzzy inclusion.
• line_circle_intr
  Finds the intersects between a line segment and a circle.
• line_line_intr
  Finds the intersects between two lines segments.
• line_seg_closest_point
  Returns the closest point on the line segment from p0 to p1 to the point given.
• midpoint
  Midpoint of a line segment defined by p0 to p1.
• min_max
  Returns the (min, max) values from v1 and v2.
• normalize_radians
  Normalize radians to be between 0 and 2PI, e.g. -PI/4 becomes 7PI/4 and 5PI becomes PI.
• parametric_from_point
  Returns the parametric value on the line segment going from p0 to p1 at the point given.
• point_from_parametric
  Returns the point on the line segment going from p0 to p1 at parametric value t.
• point_on_circle
  Returns the point on the circle with radius, center, and polar angle in radians given.
• point_within_arc_sweep
  Test if a point is within a arc sweep angle region.
• quadratic_solutions
