◆ NormalizedAngleFrom()

float NormalizedAngleFrom ( FPOINT Point1,
FPOINT Point2,
float  FullScale 
)

Return the angle from Point1 to Point2 normalized to lie in the range 0 to FullScale (where FullScale corresponds to 2*pi or 360 degrees).

Parameters
Point1points to compute angle between
Point2points to compute angle between
FullScalevalue to associate with 2*pi
Returns
angle
