Function Documentation

template<int N, typename T> ShGeneric< N, T > ShUtil::deprecated_smoothstep (  const ShGeneric< N, T > &  a, const ShGeneric< N, T > &  b, const ShGeneric< N, T >  x )

Cubic interpolated step between 0 and 1. Returns 0 if x < a, 1 if x > b, cubic interpolation between 0 and 1 otherwise Definition at line 36 of file ShFuncImpl.hpp. References SH::clamp(), and SH::mad().

template<int N, typename T> ShGeneric< N, T > ShUtil::hashlcg (  const ShGeneric< N, T > &  p  )

Parallel linear congruential generator. This does not work very well right now. Use hashmrg instead. See also: template<int N, typename T> ShGeneric<N, T> hashmrg(const ShGeneric<N, T>& p) Definition at line 54 of file ShFuncImpl.hpp. References SH::frac(), and SH::mad().
