Detailed Description

Class to create a Turing noise texture using multiple threads if needed.

Constructor & Destructor Documentation

WTuringTextureCreator()

WTuringTextureCreator::WTuringTextureCreator

(

std::size_t

numThreads = boost::thread::hardware_concurrency()

)

Constructor.

Initializes threading but does not yet start texture creation.

Parameters

numThreads

the number of threads to use. By default, this is the number of threads natively supported by the CPU.

Definition at line 35 of file WTuringTextureCreator.cpp.

References m_threads.

~WTuringTextureCreator()

WTuringTextureCreator::~WTuringTextureCreator

(

)

Destructor.

Member Function Documentation

create()

osg::ref_ptr< WGETexture3D > WTuringTextureCreator::create	(	std::size_t	sizeX,
		std::size_t	sizeY,
		std::size_t	sizeZ
	)

Create the Turing noise texture of arbitrary size.

This function is synchronous and returns a valid texture.

Parameters

sizeX	the size along the x axis.
sizeY	the size along the y axis.
sizeZ	the size along the z axis.

Returns

the texture.

References m_numIterations, m_spotIrregularity, m_spotSize, and m_threads.

setNumIterations()

void WTuringTextureCreator::setNumIterations

(

std::size_t

iter

)

The number of iterations to use for calculating the texture.

Parameters

iter	the number of iterations. 100 is recommended, lower values create a noisy texture, higher values cause the spots to be rather smooth.

Definition at line 52 of file WTuringTextureCreator.cpp.

References m_numIterations.

setSpotIrregularity()

void WTuringTextureCreator::setSpotIrregularity

(

float

irr

)

The irregularity of the spots.

Parameters

irr	the irregularity in [0,1]; 0 producing a very regular grid of spots, whereas 1 causes the spots to be rather irregular.

Definition at line 59 of file WTuringTextureCreator.cpp.

References m_spotIrregularity.

setSpotSize()

void WTuringTextureCreator::setSpotSize

(

float

size

)

Define the size of the spots inside the texture.

Parameters

size	the size in [0,1], 1 meaning larger spots.

Definition at line 66 of file WTuringTextureCreator.cpp.

References m_spotSize.
