Detailed Description

Generates a 2D float value uniformly distributed in an oriented box (OB).

Constructor & Destructor Documentation

Menge::Math::OBBUniformPosGenerator::OBBUniformPosGenerator	(	const Vector2 &	minPt,
		const Vector2 &	size,
		float	theta,
		int	seed = 0
	)

Constructor.

Parameters

minPt	The anchor point of the OB.
size	The size of the OB.
theta	The rotation around the achor point (in degrees) of the OB.
seed	If the seed is zero, the global seed will be used otherwise the particular seed will be used.

Menge::Math::OBBUniformPosGenerator::OBBUniformPosGenerator

(

const OBBUniformPosGenerator &

obbGen

)

Copy constructor.

Parameters

obbGen

The generator to copy its values from.

Member Function Documentation

Vec2DGenerator * Menge::Math::OBBUniformPosGenerator::copy ( ) const

virtual

Create a copy of itself.

Returns

A pointer to a new generator which is a copy of this one. The caller of this function is responsible for freeing up the memory for the copy.

Implements Menge::Math::Vec2DGenerator.

Vector2 Menge::Math::OBBUniformPosGenerator::getValue ( ) const

virtual

Return a value based on the 2D float generation rules.

Returns

A constat position uniformly samples from an OB.

Implements Menge::Math::Vec2DGenerator.

Vector2 Menge::Math::OBBUniformPosGenerator::getValueConcurrent ( ) const

virtual

Return a value based on the 2D float generation rules - performed in a thread-safe manner.

This is the basic functionality that must be overwridden by derived classes.

Returns

A 2D float value.

Implements Menge::Math::Vec2DGenerator.

void Menge::Math::OBBUniformPosGenerator::print ( Logger &  out ) const

virtual

Function for converting the generator to a string on a output stream.

Parameters

out	The output stream to write the string representation to.

Implements Menge::Math::Vec2DGenerator.

Friends And Related Function Documentation

Logger& operator<< ( Logger &  out, const OBBUniformPosGenerator &  gen  )

friend

Friend function for writing string representation to an output stream.

Parameters

out	The output stream.
gen	An instance of the generator to represent as a string.

Returns

Reference to the input output stream.
