Detailed Description

This class is an interface class used to compute the intersection between an algebraic object and a parametric object.

The algebraic object is "plugged" into the parametric object, resulting in a scalar function. We then use the IntersectorFuncConst class to find the intersection.

Constructor & Destructor Documentation

Go::IntersectorAlgPar::IntersectorAlgPar	(	boost::shared_ptr< AlgObjectInt >	alg_obj,
		boost::shared_ptr< ParamObjectInt >	param_obj,
		boost::shared_ptr< GeoTol >	epsge,
		Intersector *	prev = 0,
		int	eliminated_parameter = -1,
		double	eliminated_value = 0
	)

Constructor.

The last two variables are relevant only if the parent has one more parameter than the Intersector to be constructed.

Parameters:

	alg_obj	the algebraic object.
	param_obj	the parametric object.
	epsge	the associated tolerance.
	prev	the "parent" Intersector (0 if there is no parent).
	eliminated_parameter	the index of the parameter that was removed from the parent prev.
	eliminated_value	the value of the parameter that was removed from the parent prev.

virtual void Go::IntersectorAlgPar::compute

(

bool

compute_at_boundary = true

)

[virtual]

Compute the current intersections (topology).

Parameters:

compute_at_boundary

flag to indicate that we compute at the boundary

Reimplemented from Go::Intersector.

		std::vector< boost::shared_ptr< IntersectionCurve > > &	int_curves
	)			[virtual]

Return intersection points and curves.

Parameters:

	int_points	vector of shared pointers to IntersectionPoints
	int_curves	vector of shared pointers to IntersectionCurves

Reimplemented from Go::Intersector.

virtual int Go::IntersectorAlgPar::numParams

(

)

const [virtual]

Return the number of parameter directions for the object.

Returns:

thenumber of parameter directions
