Constructor & Destructor Documentation

PerlinRodSdf() [1/2]

PerlinRodSdf::PerlinRodSdf	(	const Real &	a_rad,
		const RealVect &	a_center1,
		const RealVect &	a_center2,
		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
	)

Constructor.

Parameters

[in]	a_rad	Rod radius
[in]	a_center1	One end of the rod
[in]	a_center2	Other end of the rod.
[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.
