Function Documentation

template<int N, typename T> ShGeneric< N, T > SH::acos (  const ShGeneric< N, T > &  var  )

Arccosine. Operates componentwise on tuples. A value of x in [-1, 1] gives a result in [0, pi]. Input values outside the range [-1,1] will give undefined results. Definition at line 34 of file ShLibTrigImpl.hpp. Referenced by SH::acos(), and ShUtil::ShObjMesh::generateSphericalTexCoords().

template<int N, typename T> ShGeneric< N, T > SH::asin (  const ShGeneric< N, T > &  var  )

Arcsine. Operates componentwise on tuples. A value of x in [-1, 1] gives a result in [-pi/2, pi/2]. Input values outside the range [-1,1] will give undefined results. Definition at line 42 of file ShLibTrigImpl.hpp. Referenced by SH::asin().

template<int N, typename T> ShGeneric< N, T > SH::atan (  const ShGeneric< N, T > &  var  )

Arctangent. Operates componentwise on tuples. Gives a result in [-pi/2, pi/2]. Definition at line 50 of file ShLibTrigImpl.hpp. Referenced by SH::atan().

template<int N, typename T> ShGeneric< N, T > SH::atan2 (  const ShGeneric< N, T > &  y, const ShGeneric< N, T > &  x )

Arctangent of two variables. Operates componentwise on tuples of y/x. Gives a result in [-pi/2, pi/2]. Definition at line 58 of file ShLibTrigImpl.hpp. Referenced by SH::atan2(), and ShUtil::ShObjMesh::generateSphericalTexCoords().

template<int N, typename T> ShGeneric< N, T > SH::cos (  const ShGeneric< N, T > &  var  )

Cosine. Operates componentwise on tuples. Returns the cosine of x. Any value of x gives a result in the range [-1,1]. Definition at line 66 of file ShLibTrigImpl.hpp. Referenced by SH::cos(), and ShUtil::ShKernelLight::spotLight().

template<int N, typename T> ShGeneric< N, T > SH::cosh (  const ShGeneric< N, T > &  var  )

Hyperbolic cosine. Operates componentwise on tuples. Returns the hypebolic cosine of x. Definition at line 90 of file ShLibTrigImpl.hpp.

template<int N, typename T> ShGeneric< N, T > SH::sin (  const ShGeneric< N, T > &  var  )

Sine. Operates componentwise on tuples. Returns the sine of x. Any value of x gives a result in the range [-1,1]. Definition at line 74 of file ShLibTrigImpl.hpp. Referenced by SH::sin().

template<int N, typename T> ShGeneric< N, T > SH::sinh (  const ShGeneric< N, T > &  var  )

Hyperbolic sine. Operates componentwise on tuples. Returns the hyperbolic sine of x. Definition at line 98 of file ShLibTrigImpl.hpp.

template<int N, typename T> ShGeneric< N, T > SH::tan (  const ShGeneric< N, T > &  var  )

Tangent. Operates componentwise on tuples. Returns the tangent of x. Equivalent to sin(x)/cos(x). Definition at line 82 of file ShLibTrigImpl.hpp. Referenced by SH::tan().

template<int N, typename T> ShGeneric< N, T > SH::tanh (  const ShGeneric< N, T > &  var  )

Hyperbolic tangent. Operates componentwise on tuples. Returns the hyperbolic tangent of x. Equivalent to sinh(x)/cosh(x). Definition at line 106 of file ShLibTrigImpl.hpp.
