Detailed Description

template<typename T, typename ArgType>
struct BTK::CachedUnaryFunction< T, ArgType >

a lookup-table based function approximator

when constucted from a function object (func), this class samples the function within a specified range and stores the results in a lookup table. When called it approximates the function value by returning the linear interpolate of the two nearest sample points.
