Detailed Description

This class is a sea elevation module that combines several effects:
Waves, defined by direction, amplitude, period and optionally, phase.

Perlin noise, used to randomize the sea surface. Pressure points, used to create puntual waves.

Constructor & Destructor Documentation

◆ Real()

Hydrax::Noise::Real::Real ( )

Default constructor.

Definition at line 38 of file Real.cpp.

◆ ~Real()

Hydrax::Noise::Real::~Real ( )

Destructor.

Definition at line 47 of file Real.cpp.

Member Function Documentation

◆ addPressurePoint()

int Hydrax::Noise::Real::addPressurePoint	(	Ogre::Vector2	Orig,
		float	p,
		float	T,
		float	L
	)

Adds a pressure point to the system.

Parameters

Orig	Origin of perturbation.
p	Pressure pulse (N·m). The maximum half-amplitude of the wave will result from divide this value with g*rho. So, a pressure of 10000 N·m produces 2 m waves.
T	Maximum time of perturbation (s). The effect of the perturbation will decay. When T time will be elapsed, any effects will remain.
L	wave length. To objects falling, similar values to amplitude can be OK. For ships Kelvin wakes probably length of the ship is a better choice.

Returns: Id of the pressure point.

Warning: Pressure point will be autodestroyed when it have not any effect, so it's not available any modify after the creation.

Definition at line 92 of file Real.cpp.

◆ addWave()

int Hydrax::Noise::Real::addWave	(	Ogre::Vector2	dir,
		float	A,
		float	T,
		float	p = `0.f`
	)

Adds a wave to the system.

Parameters

dir	Direction of the wave.
A	Amplitude of the wave (m).
T	Period of the wave (s).
