Detailed Description

Infinite plane with surface noise (Perlin noise).

Constructor & Destructor Documentation

PerlinPlaneSdf::PerlinPlaneSdf	(	const RealVect	a_normal,
		const RealVect	a_point,
		const bool	a_inside,
		const Real	a_noiseAmp,
		const RealVect	a_noiseFreq,
		const Real	a_persistence,
		const int	a_octaves,
		const bool	a_reseed = `false`
	)

Full constructor.

Parameters

[in]	a_point	Point on the plane
[in]	a_normal	Plane normal vector
[in]	a_inside	Inside or outside
[in]	a_noiseAmp	Noise amplitude
[in]	a_noiseFreq	Noise frequency
[in]	a_persistence	Factor for noise octaves.
[in]	a_octaves	Number of octaves
[in]	a_reseed	If true, reseed the RNG. Otherwise, the the original Perlin hash table.

Note: The persistence argument indicates how we add octaves. With 0.5 we use half the amplitude and twice the frequency for the next octave.
