Member Function Documentation

void dtUtil::SeamlessNoise::Reseed

(

unsigned int

seed

)

Regenerates the random numbers using the given seed.

Parameters:

seed

new seed value

float dtUtil::SeamlessNoise::GetNoise	(	const osg::Vec3f &	vect_in,
		int	repeat = -1
	)

Parameters:

vect_in

a 3D Vector to hash the noise to, for 2D noise pass in a constant z value

Parameters:

repeat

pass in the frequency or the desired resolution to tile the noise in if this param is not passed in the default value will be used

Returns:

a float from -1 to 1

void dtUtil::SeamlessNoise::SetRepeat

(

int

pRepeat

)

[inline]

The SetRepeat function will allow a user to change the frequency the noise function will repeat.
