Detailed Description

Gaussian sequence of pseudo random numbers implemented with the Box-Mueller transform.

vtkGaussianRandomSequence is a sequence of pseudo random numbers distributed according to the Gaussian/normal distribution (mean=0 and standard deviation=1).

It based is calculation from a uniformly distributed pseudo random sequence. The initial sequence is a vtkMinimalStandardRandomSequence.

Member Function Documentation

static int vtkBoxMuellerRandomSequence::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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.

Reimplemented from vtkGaussianRandomSequence.

virtual int vtkBoxMuellerRandomSequence::IsA ( const char * name ) [virtual]

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.

Reimplemented from vtkGaussianRandomSequence.

static vtkBoxMuellerRandomSequence* vtkBoxMuellerRandomSequence::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkGaussianRandomSequence.

virtual vtkObjectBase* vtkBoxMuellerRandomSequence::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkGaussianRandomSequence.

vtkBoxMuellerRandomSequence* vtkBoxMuellerRandomSequence::NewInstance ( ) const

Reimplemented from vtkGaussianRandomSequence.

void vtkBoxMuellerRandomSequence::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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 vtkGaussianRandomSequence.

static vtkBoxMuellerRandomSequence* vtkBoxMuellerRandomSequence::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual double vtkBoxMuellerRandomSequence::GetValue ( ) [virtual]

Current value.

Implements vtkRandomSequence.

virtual void vtkBoxMuellerRandomSequence::Next ( ) [virtual]

Move to the next number in the random sequence.

Implements vtkRandomSequence.

vtkRandomSequence* vtkBoxMuellerRandomSequence::GetUniformSequence ( )

Return the uniformly distributed sequence of random numbers.
