Function Documentation

GLUSboolean GLUSAPIENTRY glusRandomHammersleyf	(	GLUSfloat	result[2],
		const GLUSuint	sample,
		const GLUSubyte	m
	)

Samples two floating point values from a Hammersley point set.

Parameters

result	The resulting random values.
sample	The sample to take. Has to be in the range 0 <= sample < 2^m.
m	Order m, which allows 2^m samples. Has to be in the range 0 < m <= 32.

Returns

GLUS_TRUE, if sampling was successful.

GLUSfloat GLUSAPIENTRY glusRandomNormalf	(	const GLUSfloat	mean,
		const GLUSfloat	standardDeviation
	)

Returns a normal distributed random floating point value.

Parameters

mean	Mean.
standardDeviation	Standard deviation.

Returns

The random value.

GLUSvoid GLUSAPIENTRY glusRandomSetSeed

(

const GLUSuint

seed

)

Initializes the random generator.

Parameters

seed	Number for initializing the pseudo-random number generator.

GLUSfloat GLUSAPIENTRY glusRandomUniformf	(	const GLUSfloat	start,
		const GLUSfloat	end
	)

Returns a uniform distributed random floating point value in the given range.

Parameters

start	Smallest possible generated value (inclusive).
end	Largest possible generated value (inclusive).

Returns

The random value.
