template<class RNG >

void swri_math_util::GetUniformRandomSample	(	RNG &	rng,
		int32_t	min,
		int32_t	max,
		int32_t	count,
		std::vector< int32_t > &	sample
	)

Gets a uniform random sample of integers without repeats for a given range.

The number of samples should be much smaller than the number of possible values in the range for optimal performance.

This function depends on a random number generator (RNG) being provided, which generally aren't thread safe. It is recommended that a multi-threaded application create a seperate RNGs for each thread.

param[in] rng The random number generator. param[in] min The minimum of the range (inclusive). param[in] max The maximum of the range (inclusive). param[in] count The sample size. param[out] sample The sample.

bool swri_math_util::IsNear	(	double	v1,
		double	v2,
		double	epsilon
	)

Check if v1 is within +/- epsilon of v2

Parameters:

[in]	v1	The first value.
[in]	v2	The second value.
[in]	epsilon	The tolerance.

Returns:: True if v1 is near v2.

Definition at line 61 of file math_util.cpp.

double swri_math_util::Round ( double value )

Round the value to the nearest integer.

Parameters:

[in]	value	The number to round.
[in]	multiple	The multiple.

Returns:: The rounded value.

Definition at line 36 of file math_util.cpp.

double swri_math_util::ToDegrees ( double radians )

Convert degrees to radians.

Parameters:

[in] radians Input angle.

Returns:: The angle in degrees.

Definition at line 57 of file trig_util.cpp.

double swri_math_util::ToNearest	(	double	value,
		double	multiple
	)

Round the value to the nearest provided multiple.

Parameters:

[in]	value	The number to round.
[in]	multiple	The multiple.

Returns:: The rounded value.

Definition at line 41 of file math_util.cpp.

double swri_math_util::ToRadians ( double degrees )

Convert radians to degrees.

Parameters:

[in] degrees Input angle.

Returns:: The angle in radians.

Definition at line 52 of file trig_util.cpp.

double swri_math_util::unWrapAngle	(	double	static_angle,
		double	variable_angle,
		double	threshold = `_pi`
	)

Unwraps the variable_angle across 0-2pi or +/-pi boundaries to avoid large differences between the static and variable angles (when the difference may be small. For example a static angle of 2pi - epsilon and a variable angle of epsilon would result in the variable angle being unwrapped to 2pi + epsilon.

Parameters:

[in]	static_angle	The reference angle
[in]	variable_angle	The angle to unwrap
[in]	threshold	A threshold on the angle (default is pi)

Return values:

Returns the resultant angle

Definition at line 66 of file math_util.cpp.

double swri_math_util::UpToNearest	(	double	value,
		double	multiple
	)

Round up the value to the nearest provided multiple.

Parameters:

[in]	value	The number to round.
[in]	multiple	The multiple.

Returns:: The rounded value.

Definition at line 51 of file math_util.cpp.

double swri_math_util::WrapRadians	(	double	angle,
		double	center
	)

Normalize an angle to be within a 2pi range centered at a given value.

Parameters:

[in]		angle The input angle in radians.
[in]		center The center of the range in radians.

Returns:: An equivalent angle in the desired range.
