Detailed Description

template<typename REAL, bool USEFILTER = true, bool EXACT = true>
class UT_GeometryPredicates< REAL, USEFILTER, EXACT >

Use the following class in places where you can specify the bounding box of all the points you will use with these geometry predicates. If the bounding box is not known, use the functions at the global scope (note that those will be slower since there are additional static filters based on the bounding box size used in this class.
