Functions
template<int Order, typename TreeOrAccT, bool UseCache = true>
SampleFromVoxels< TreeOrAccT, Order, UseCache >	createSampler (const TreeOrAccT &acc)
	Factory free-function for a sampler of specific polynomial orders.
template<typename CoordT, typename RealT, template< typename > class Vec3T>
CoordT	Floor (Vec3T< RealT > &xyz)
	Utility function that returns the Coord of the round-down of xyz and redefined (x, y, z) as the fractional part, ie xyz-in = return-value + xyz-out.
template<typename CoordT, template< typename > class Vec3T>
CoordT	Floor (Vec3T< float > &xyz)
	Template specialization of Floor for Vec3<float>
template<typename CoordT, template< typename > class Vec3T>
CoordT	Floor (Vec3T< double > &xyz)
	Template specialization of Floor for Vec3<float>
template<typename RealT, typename T>
constexpr auto	toReal (const T &v)
	Explicitly convert an integral v to RealT, i.e. the implicit promotion in mixed integer/floating-point arithmetic. All other types are returned unchanged.
template<typename T, typename S>
T	scale (const T &v, S s)
	Preserve NanoVDB vectors' component-precision scalar multiplication. For other types, multiply before converting the result back to T.

Detailed Description

NearestNeighborSampler, TrilinearSampler, TriquadraticSampler and TricubicSampler.

Note: These interpolators employ internal caching for better performance when used repeatedly in the same voxel location, so try to reuse an instance of these classes more than once.

Warning: While all the interpolators defined below work with both scalars and vectors values (e.g. float and Vec3<float>) TrilinarSampler::zeroCrossing and Trilinear::gradient will only compile with floating point value types.
