Functions

template<typename T >
osg::absolute (T v)
 return the minimum of two values, equivalent to std::min.
bool osg::equivalent (float lhs, float rhs, float epsilon=1e-6)
 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.
bool osg::equivalent (double lhs, double rhs, double epsilon=1e-6)
 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.
template<typename T >
osg::minimum (T lhs, T rhs)
 return the minimum of two values, equivalent to std::min.
template<typename T >
osg::maximum (T lhs, T rhs)
 return the maximum of two values, equivalent to std::max.
template<typename T >
osg::clampTo (T v, T minimum, T maximum)
template<typename T >
osg::clampAbove (T v, T minimum)
template<typename T >
osg::clampBelow (T v, T maximum)

template<typename T >
float osg::computeVolume (const T &a, const T &b, const T &c, const T &d)
 compute the volume of a tetrahedron.
template<typename T >
