virtual bool Go::Domain::isInDomain	(	const Array< double, 2 > &	point,
		double	tolerance
	)			const [pure virtual]

check whether a given parameter pair is located inside the domain

Parameters:

	point	the (u,v)-pair that we want to test.
	tolerance	the tolerance used (ruling what to do when 'point' is located very near the edge of the domain).

Returns:

'true' if 'point' is inside the domain, or within 'tolerance' from being inside the domain, 'false' otherwise'.

Implemented in Go::CurveBoundedDomain, and Go::RectDomain.

virtual bool Go::Domain::isOnBoundary	(	const Array< double, 2 > &	point,
		double	tolerance
	)			const [pure virtual]

check whether a given parameter pair is located on the domain boundary

Parameters:

	point	the (u,v)-pair that we want to test
	tolerance	the tolerance used (how 'far' from the boundary our (u,v) pair can be and still be considered 'on' the boundary.

Returns:

'true' if the point is considered to be on the boundary (within 'tolerance', 'false' otherwise.

Implemented in Go::CurveBoundedDomain, and Go::RectDomain.

virtual void Go::Domain::closestInDomain	(	const Array< double, 2 > &	point,
		Array< double, 2 > &	clo_pt,
		double	tolerance
	)			const [pure virtual]

Find the (u, v) point in the Domain that is closest (using Euclidean distance in R^2) to a given (u, v) point.

If the given point is in the domain, then the answer is obviously the same point.

Parameters:

	point	the (u,v) parameter pair that we want to find the closest parameter pair to inside Domain.
	clo_pt	the resulting closest parameter point.
	tolerance	the tolerance used in defining whether the given point is already inside the domain.

Implemented in Go::CurveBoundedDomain, and Go::RectDomain.

virtual void Go::Domain::closestOnBoundary	(	const Array< double, 2 > &	point,
		Array< double, 2 > &	clo_bd_pt,
		double	tolerance
	)			const [pure virtual]

Find the (u, v) point on the boundary of the Domain that is closest (using Euclidean distance in R^2) to a given (u, v) point.

If the point is already considered on the boundary, then the answer is obviously the same point.

Parameters:

	point	the (u,v) parameter pair that we want to find to closest parameter pair to on the Domain border.
	clo_bd_pt	the resulting closest border point.
	tolerance	the tolerance used in defining whether the given point is

Implemented in Go::CurveBoundedDomain, and Go::RectDomain.
