virtual boost::shared_ptr<ParamCurve> Go::NonEvaluableIntersectionCurve::getParamCurve

(

int

obj_nmb

)

const [inline, virtual]

Get out a (shared) pointer to the curve in the parametric plane of the first or second object.

Should only be called when the concerned object is 2-parametric.

Parameters:

obj_nmb

should be either 1 or 2, depending on whether you want to get the parametric curve in object 1 or object 2.

Returns:

a shared pointer to a curve that approximates the intersection curve in the parametric domain of the specified object.

Implements Go::IntersectionCurve.

virtual void Go::NonEvaluableIntersectionCurve::getParamSpan	(	double &	start,
		double &	end
	)			const [inline, virtual]

Get the start and end value for the parametric span of the IntersectionCurve.

Return values:

	start	upon function return this variable will contain the start value of the parametric span.
	end	upon function return this variable will contain the end value of the parametric span.

Implements Go::IntersectionCurve.

Definition at line 283 of file IntersectionCurve.h.

virtual void Go::NonEvaluableIntersectionCurve::evaluateAt	(	double	pval,
		Point &	pos,
		Point &	tan
	)			[inline, virtual]

Evaluate the IntersectionCurve at parameter value pval.

Its position at this parameter value will be returned in pos and its tangent direction will be returned in tan.

Parameters:

pval

the parameter value for which to evaluate the IntersectionCurve. It should be within the parametric span (which can be obtained from GetParamSpan().

Return values:

pos

the calculated position of the point on the curve at parameter pval.

Parameters:

tan

the calculated tangent of the curve at parameter pval.

Implements Go::IntersectionCurve.

virtual void Go::NonEvaluableIntersectionCurve::refine	(	const double &	pos_tol,
		const double &	angle_tol
	)			[inline, virtual]

Refine the curve (which means to increase the number of IntersectionPoint s defining it), so that the curve matches a specific positional and angle tolerance.

Parameters:

	pos_tol	the positional tolerance that the curve should match after refinement.
	angle_tol	the angular tolerance that the tangent of the curve should match after refinement.

Implements Go::IntersectionCurve.

virtual bool Go::NonEvaluableIntersectionCurve::isIsocurve

(

)

const [inline, virtual]

Determine if the IntersectionCurve is in fact representing an isoparametric intersection.

Returns:

'true' if the IntersectionCurve is part of an isocurve for one of the objects, 'false' otherwise.

Implements Go::IntersectionCurve.

Definition at line 298 of file IntersectionCurve.h.

virtual bool Go::NonEvaluableIntersectionCurve::isDegenerated

(

)

const [inline, virtual]

Determine if the IntersectionCurve is in fact a degenerated curve (a single point in space).

Returns:

'true' if the IntersectionCurve is degenerated. 'false' otherwise.

Implements Go::IntersectionCurve.
