Function Documentation

GetFaces()

template<class out_cont_t , class plane_it >

int GetFaces	(	out_cont_t &	cont,
		plane_it	beg,
		plane_it	end,
		const std::vector< int > *	redundant_planes = nullptr,
		std::vector< int > *	valid_planes = nullptr
	)

gets all faces of the polyhedral region defined by planes from [beg, end) of type plane_it puts the faces as planar contours into container cont using push_back(...) Parameter redundant_planes specifies the order number of planes that can not form faces.

The order number of planes that actually form faces are placed in output parameter valid_planes, if specified.

Returns

the number of faces

GetPlaneSection()

template<class contour_t >

int GetPlaneSection	(	const contour_t &	cnt,
		const Plane_3 &	plane,
		contour_t *	cnt_in = nullptr,
		contour_t *	cnt_out = nullptr
	)

Tests whether the contour crosses the plane and optionally outputs inside (side of plane distance >0) and outside subcontours.

Returns

0, if there is a crossing

1, if the contour is fully inside plane

-1, if the contour is fully outside plane
