Member Function Documentation

static double Math::angleToPercent	(	double	newAngle,
		double	oldAngle
	)		[inline, static]

Returns:

ratio between one dimension seen under old viewangle and dimension under new viewangle

Definition at line 67 of file Math.h.

static float Math::angleVariance	(	float	meanAngle,
		const std::vector< float > &	angles
	)		[static]

Returns:

variance for given mean

static Point2D Math::center

(

std::vector< Point2D > &

points

)

[static]

static float Math::deg2Rad

(

float

deg

)

[inline, static]

Definition at line 58 of file Math.h.

static double Math::horizontalViewAngle	(	double	diagonalAngle,
		double	aspectRatio
	)		[inline, static]

Returns:

horizontal view angle corresponding to diagonal view angle and aspect ratio (e.g. 4.0/3.0)

Definition at line 73 of file Math.h.

template<class ValueT >

static ValueT Math::max	(	ValueT	a,
		ValueT	b
	)		[inline, static]

Definition at line 85 of file Math.h.

template<class ContainerT >

double Math::mean

(

const ContainerT &

values

)

[static]

Returns:

mean value

Definition at line 98 of file Math.h.

static float Math::meanAngle

(

const std::vector< float > &

angles

)

[static]

Returns:

mean angle of given values

Note:

there are always two possible choices for the mean angle. This function returns the one with the smallest deviation

Works for angles in [-Pi..Pi], negative angles are treated

static float Math::meanAngleWeighted

(

const std::vector< WeightedValue > &

weightedAngles

)

[static]

template<class ValueT >

static ValueT Math::min	(	ValueT	a,
		ValueT	b
	)		[inline, static]

Definition at line 82 of file Math.h.

static float Math::minTurnAngle	(	float	angle1,
		float	angle2
	)		[static]

Returns:

minimal angle needed to turn from angle 1 to angle 2 [-Pi..Pi]

static double Math::percentToAngle	(	double	percent,
		double	angle
	)		[inline, static]

Returns:

angle under which the ratio between dimension seen under old viewangle and new viewangle equals percent

Definition at line 70 of file Math.h.

static float Math::rad2Deg

(

float

rad

)

[inline, static]

Definition at line 60 of file Math.h.

static double Math::random01

(

unsigned long

init = 0

)

[static]

static double Math::randomGauss

(

variance = 1.0

)

[static]

template<class ContainerT >

double Math::variance

(

const ContainerT &

values

)

[static]

Returns:

variance of given values

Definition at line 113 of file Math.h.

static double Math::verticalViewAngle	(	double	diagonalAngle,
		double	aspectRatio
	)		[inline, static]

Returns:

vertical view angle corresponding to diagonal view angle and aspect ratio (e.g. 4.0/3.0)

Definition at line 76 of file Math.h.
