Detailed Description

Infinite plane with surface noise (Perlin noise).

Constructor & Destructor Documentation

PerlinPlaneSdf() [1/2]

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.
