Measures the angle defined by three consecutive points.
| Name | Type | Description | |
|---|---|---|---|
 |
inPoint1 | Point2D | A point on one arm of an angle |

inPoint2 | Point2D | The middle point |
|
inPoint3 | Point2D | A point on another arm of the angle |
|
inRotationDirection | RotationDirection | Chooses one of two ways of measuring the angle |
 |
outAbsoluteAngle | Real | Angle value used for measurements <0; 360> |
|
outDirectedAngle | Real | Angle value used for clockwise transformations <-360; 360> |
|
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.
