Detailed Description

GradedPerlinSphereSdf function.

This class is a sphere with graded noise – there is only noise on one side of the sphere.

Constructor & Destructor Documentation

GradedPerlinSphereSdf() [1/2]

GradedPerlinSphereSdf::GradedPerlinSphereSdf	(	const Real &	a_rad,
		const RealVect &	a_center,
		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_rad	Sphere radius
[in]	a_center	Sphere center
[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.
