Detailed Description

Implicit function class describing a slab (box) with surface noise on the top.

Constructor & Destructor Documentation

PerlinSlabSdf::PerlinSlabSdf	(	const RealVect	a_ccPoint,
		const RealVect	a_normal,
		const RealVect	a_xyz,
		const RealVect	a_noiseFreq,
		const int	a_octaves,
		const Real	a_noiseAmp,
		const Real	a_persistence,
		const Real	a_cornerCurv,
		const bool	a_reseed,
		const bool	a_fluidInside
	)

Constructor.

Parameters

[in]	a_ccPoint	Center point on the slab side with surface noise
[in]	a_normal	Normal vector of slab side with surface noise
[in]	a_xyz	Width, depth, and height of slab
[in]	a_curv	Corner curvatures
[in]	a_noiseFreq	Noise frequency
[in]	a_octaves	Number of octaves
[in]	a_noiseAmp	Noise amplitude
[in]	a_persistence	Factor for noise octaves.
[in]	a_cornerCurv	Corner curvatures
[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.

Parameters

[in] a_fluidInside Fluid on inside or not

Real PerlinSlabSdf::value ( const RealVect & a_pos ) const

overridevirtual

Value function. Returns distance to object.

Parameters

[in] a_pos Position.
