AngleBetweenThreePoints

Basic

Module: FoundationLite

Measures the angle defined by three consecutive points.

Name Type Description
Input value inPoint1 Point2D A point on one arm of an angle
Input value inPoint2 Point2D The middle point
Input value inPoint3 Point2D A point on another arm of the angle
Input value inRotationDirection RotationDirection Chooses one of two ways of measuring the angle
Output value outAbsoluteAngle Real Angle value used for measurements <0; 360>
Output value outDirectedAngle Real Angle value used for clockwise transformations <-360; 360>
Output value outArc Arc2D Angle visualization object

Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when some two of the input points are almost equal.
