template<typename T> T osg::absolute (  T  v  )  [inline]

return the minimum of two values, equivalent to std::min. std::min not used because of STL implementation under IRIX not containing std::min.

template<typename T> T osg::clampAbove (  T  v, T  minimum )  [inline]

template<typename T> T osg::clampBelow (  T  v, T  maximum )  [inline]

template<typename T> T osg::clampBetween (  T  v, T  minimum, T  maximum )  [inline]

template<typename T> T osg::clampTo (  T  v, T  minimum, T  maximum )  [inline]

template<typename T> float osg::computeVolume (  const T &  f1, const T &  f2, const T &  f3, const T &  b1, const T &  b2, const T &  b3 )  [inline]

compute the volume of a prism.

template<typename T> float osg::computeVolume (  const T &  a, const T &  b, const T &  c, const T &  d )  [inline]

compute the volume of a tetrahedron.

double osg::DegreesToRadians (  double  angle  )  [inline]

float osg::DegreesToRadians (  float  angle  )  [inline]

double osg::equivalent (  double  lhs, double  rhs, double  epsilon = 1e-6 )  [inline]

return true if double lhs and rhs are equivalent, meaning that the difference between them is less than an epsilon value which defaults to 1e-6.

float osg::equivalent (  float  lhs, float  rhs, float  epsilon = 1e-6 )  [inline]

return true if float lhs and rhs are equivalent, meaning that the difference between them is less than an epsilon value which defaults to 1e-6.

double osg::inDegrees (  double  angle  )  [inline]

float osg::inDegrees (  float  angle  )  [inline]

template<typename T> T osg::inRadians (  T  angle  )  [inline]

bool osg::isNaN (  double  v  )  [inline]

bool osg::isNaN (  float  v  )  [inline]

template<typename T> T osg::maximum (  T  lhs, T  rhs )  [inline]

return the maximum of two values, equivilent to std::max. std::max not used because of STL implementation under IRIX not containing std::max.

template<typename T> T osg::minimum (  T  lhs, T  rhs )  [inline]

return the minimum of two values, equivilent to std::min. std::min not used because of STL implementation under IRIX not containing std::min.

double osg::RadiansToDegrees (  double  angle  )  [inline]

float osg::RadiansToDegrees (  float  angle  )  [inline]

template<typename T> T osg::sign (  T  v  )  [inline]

template<typename T> T osg::signedSquare (  T  v  )  [inline]

template<typename T> T osg::square (  T  v  )  [inline]
