Classes
struct	IntersectionPoint

Public Types
typedef QPair< int, int >	SegmentId
	Discontinuity index, segment index in the original discontinuity info.

Public Member Functions
void	print (const GmLogCategory &logger, GmLogLevel level) const
	Prints the contents of the intersection to the given logger.

Static Public Member Functions
static const char *	kindToStr (GmSegmentCellIntersectionPointKind kind)
	Returns a string representation for the given kind.

Public Attributes
int	_cellId
	The cell id.
SegmentId	_segmentId
	The segment id (discontinuity id + segment index in the original discontinuity info)
IntersectionPoint	_in
	The data for the first intersection point in the polyline direction.
IntersectionPoint	_out
	The data for the second intersection point in the polyline direction.
int	_edge
	In 2D or 3D, if the segment lies over an edge, stores the edge number. -1 otherwise.
int	_face
	In 3D, if the segment lies over a face, stores the face number. -1 otherwise.
bool	_continuous
	A flag set to true if this intersection segment start point is the same as the last point for the previous intersection.
bool	_single
	A flag set to true if in & out where collapsed into a single point.

Detailed Description

Representation for the intersection between a polyline segment and a mesh cell. Can be used both in 2D and in 3D.

This is a rather large structure, mainly because it stores GmVector objects (each one statically reserving 16 array entries) to cope with 2/3 cartesian coordinates and from 2 to 4 natural coordinates.

In this way, it is a convenient class for use when searching for the intersections, but NOT for STORING the results. For that we use the GmCompact2DSegmentCellIntersection or GmCompact3DSegmentCellIntersection classes.
