public static void AngleBetweenVectors ( AvlNet.Vector2D inVector1, AvlNet.Vector2D inVector2, AvlNet.RotationDirection? inRotationDirection, out float outAbsoluteAngle, out float outDirectedAngle )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inVector1 | AvlNet.Vector2D | Start vector. | |||
inVector2 | AvlNet.Vector2D | Target vector. | |||
inRotationDirection | AvlNet.RotationDirection? | Clockwise, counter-clockwise or automatic (by smaller angle). Default value: atl::NIL. | |||
outAbsoluteAngle | float | Angle value used for measurements <0; 360> | |||
outDirectedAngle | float | Angle value used for clockwise transformations <-360; 360> |
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 a zero vector is given on input.
