Member Function Documentation

ClipAngleToCycle()

double UYasiuMathFunctionLibrary::ClipAngleToCycle	(	double	angle,
		double	period )

Normalize angle to its period, to be in range <0, period>.

Warning

Does not support negative periods

ConvexHull2D()

void UYasiuMathFunctionLibrary::ConvexHull2D	(	TArray< int > &	result,
		const TArray< FVector2D > &	polygonPoints )

Find points that create convex hull in 2D Space

Parameters

result	Result array of input point indexes
polygonPoints	Array of points in 2D Space

FindMinimalRadiusForIntersectingTangentsOnArc()

double UYasiuMathFunctionLibrary::FindMinimalRadiusForIntersectingTangentsOnArc	(	double	alfa,
		double	beta,
		double	symmetricWidth )

Find radius of circle for both tangent lines that intersect. Tangents on circle are defined by angle Alfa and Beta. Tangent line distance to meeting point from circle intersection is symmetricWidth. Angle is in radians.

\[ R=\frac{\sin(\alpha)*A-\sin(\beta)*B}{\cos(\beta)-\cos(\alpha)} \]

Parameters

alfa	Tangent point location defined by angle
beta	Tangent point location defined by angle
symmetricWidth	Width from tangent point to intersect

FindMinimalRadiusForIntersectingTangentsOnArcAsymmetric()

FVector2D UYasiuMathFunctionLibrary::FindMinimalRadiusForIntersectingTangentsOnArcAsymmetric	(	double	alfa,
		double	beta,
		double	widthA,
		double	widthB )

Find radius of circle for both tangent line that intersect. Asymmetry comes from 2 different widths. Tangents on circle are defined by angle Alfa and Beta. Tangent line distance to meeting point from circle intersection is symmetricWidth. Angle is in radians. First radius is bigger.

\[ R=\frac{\sin(\alpha)*A-\sin(\beta)*B}{\cos(\beta)-\cos(\alpha)} \]

Parameters

alfa	Tangent point location defined by angle
beta	Tangent point location defined by angle
widthA	Distance from intersection for point A
widthB	Distance from intersection for point B

Returns

SpreadPointsOnTangentByAngleRadius()

void UYasiuMathFunctionLibrary::SpreadPointsOnTangentByAngleRadius	(	TArray< FVector2D > &	out,
		double	angle,
		double	radius,
		double	spreadDistance )

Spread points on tangent line to arc located by angle and radius of given arc. Points are moved away from tangent point by spreadDistance

Parameters

angle	Tangent location defined by angle
radius	Radius of arc
spreadDistance	Distance to spread in one direction from tangent point

Returns

TArray of 2 points

SpreadPointsOnTangentByXY()

void UYasiuMathFunctionLibrary::SpreadPointsOnTangentByXY	(	TArray< FVector2D > &	out,
		const double	X,
		const double	Y,
		const double	spreadDistance )

Parameters

X	Position X
Y	Position Y
spreadDistance	Distance to spread in one direction from tangent point

Returns

TArray of 2 points
