Detailed Description

template<typename T>
class IntersectionSet< T >

Represents a set of intersections. Typically, an instance of this object will only contain intersections with the same spline. Implements the algorithms relevant for multiple instersections.

Definition at line 13 of file intersection_set.hpp.

Constructor & Destructor Documentation

template<typename T>
IntersectionSet< T >::IntersectionSet ( )
inline

Initialize everything to zero except the algorithm parameters: For direction estimation: cosTheta cutoff will be 0.07 < abs(cosTheta) < 0.9 A will be 10.0 For velocity estimation: cosTheta cutoff will be 0.17 < abs(cosTheta) < 1.0

Definition at line 25 of file intersection_set.hpp.
