Function Documentation

template<int M, int N, typename T> ShGeneric< M, T > SH::cast (  const ShGeneric< N, T > &  a  )  [inline]

Casting. Casts ShGeneric<N, T> to ShGeneric<M, T>. If M > N, pads remaining components with 0s (on right). Otherwise, discards extra components. Definition at line 38 of file ShLibMiscImpl.hpp.

template<int N, typename T> void SH::discard (  const ShGeneric< N, T > &  c  )  [inline]

Fragment discard. Only for fragment programs. Discards the current fragment if any(c) > 0. Definition at line 94 of file ShLibMiscImpl.hpp. Referenced by SH::kill().

template<int M, int N, typename T> ShGeneric< M, T > SH::fillcast (  const ShGeneric< N, T > &  a  )  [inline]

Fill Casting. Casts ShGeneric<N, T> to ShGeneric<M, T>. If M > N, copies last component to fill extra slots. Otherwise, discards extra components. Definition at line 65 of file ShLibMiscImpl.hpp.

template<typename T> ShProgram SH::freeze (  const ShProgram &  p, const T &  uniform )

Uniform freezing. Replace uses of the given uniform in the given program with a constant containing its current value, and return the resulting program. Definition at line 107 of file ShLibMiscImpl.hpp.

template<int N, typename T> void SH::kill (  const ShGeneric< N, T > &  c  )  [inline]

Fragment killing. Deprecated: Use discard instead. Definition at line 101 of file ShLibMiscImpl.hpp. References SH::discard().
