Functions
float	pnm::test::sphereLatticeSdf (int gx, int gy, int gz, std::array< int, 3 > gd)
	2x2x2 lattice of SOLID spheres in a periodic box (min-image distance); pores at the interstices.
float	pnm::test::trigSdf (int gx, int gy, int gz, std::array< int, 3 > gd)
	Smooth trigonometric field with wrap-around components (exercises the periodic images).
float	pnm::test::spherePoreSdf (int gx, int gy, int gz, std::array< int, 3 > c, float radius)
	One spherical PORE (SDF > 0 inside) of radius radius centred on the integer voxel c; solid everywhere outside.
float	pnm::test::twoSpherePoresSdf (int gx, int gy, int gz, std::array< int, 3 > c1, std::array< int, 3 > c2, float radius)
	Two overlapping spherical pores (the union = max of the two SDFs); a throat at the mid-plane when the centres are closer than 2*radius.
template<class SdfFn >
std::vector< float >	pnm::test::sampleGrid (std::array< int, 3 > gd, const SdfFn &fn)
	Sample fn(gx, gy, gz) over the whole gd grid in pnm's flat x-fastest layout.
