Functions |
| template<typename T> |
| 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.
