Detailed Description

Generator for Mersenne Twister pseudorandom numbers.

vtkMersenneTwister is an implementation of the Mersenne Twister pseudorandom number generator. The VTK class is simply a wrapper around an implementation written by M. Matsumoto, T. Nishimura and M. Saito, whose source code can be found at http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/DC/dc.html.

This implementation of the Mersenne Twister facilitates the generation and query from multiple independent pseudorandom sequences. Independent sequences are identified by a unique vtkMersenneTwister::SequenceId, which is either generated upon request or passed into the initialization method. This id is factored into the initialization of the Mersenne Twister's initial state, so two sequences with the same seed and different sequence ids will produce different results. Once a sequence is initialized with an associated sequence id, this id is used to obtain values from the sequence.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

static vtkMersenneTwister* vtkMersenneTwister::New ( )

static

SequenceId vtkMersenneTwister::InitializeNewSequence	(	vtkTypeUInt32	seed,
		int	p = `521`
	)

Initialize a new Mersenne Twister sequence, given a) a <seed> and b) a Mersenne exponent (p s.t.

2^p-1 is a Mersenne prime). If

is not a usable Mersenne exponent, its value is used to pick one from a list. The return value is the id for the generated sequence, which is used as a key to access values of the sequence.

void vtkMersenneTwister::InitializeSequence	(	SequenceId	id,
		vtkTypeUInt32	seed,
		int	p = `521`
	)

Initialize a sequence as in InitializeNewSequence(), but additionally pass an id to associate with the new sequence.

If a sequence is already associated with this id, a warning is given and the sequence is reset using the given parameters.

virtual double vtkMersenneTwister::GetValue ( SequenceId id )

virtual

Current value.

Postcondition: unit_range: result>=0.0 && result<=1.0

double vtkMersenneTwister::GetValue ( )

inlineoverridevirtual

Current value.

Postcondition: unit_range: result>=0.0 && result<=1.0

Implements vtkRandomSequence.

virtual void vtkMersenneTwister::Next ( SequenceId id )

virtual

Move to the next number in random sequence <id>.

If no sequence is associated with this id, a warning is given and a sequence is generated with default values.

void vtkMersenneTwister::Next ( )

inlineoverridevirtual

Move to the next number in random sequence <0>.

If no sequence is associated with this id, a warning is given and a sequence is generated with default values.
