Constructors

ContourLine3D(Vec3*array, unsigned int nb, Contour3D *c, ContourLine::Topology top=ContourLine::OPENED) throw(EmptyLine)

constructor based on an array of 3D vertices and its topology

Throws:

EmptyLine when nb=0

Parameters:

array - an array of 3D vertex position
nb - the number of vertices in the array
c - the contour where the line belongs
top - the line topology

ContourLine3D( std::list > array, unsigned int nb, Contour3D *c, ContourLine::Topology top=ContourLine::OPENED) throw(EmptyLine)

constructor based on an array of 3D vertices and its topology

Throws:

EmptyLine when nb=0

Parameters:

array - an array of 3D vertex position
nb - the number of vertices in the array
c - the contour where the line belongs
top - the line topology

ContourLine3D(unsigned int nb, Contour3D *c, ContourLine::Topology top=ContourLine::OPENED) throw(EmptyLine)

Build a line segment only by specifying the number of vertices : the vertices are then initialized along the segment defined by (0,0,0) and (1,0,0)

Throws:

EmptyLine when nb=0

Parameters:

nb - the number of vertices in the array
c - the contour where the line belongs
top - the line topology

ContourLine3D(const ContourLine3D *l, Contour3D *c)

Copy constructor

Parameters:

l - a given line
c - the contour where the line belongs

ContourLine3D(Contour3D *c, ContourLine::Topology top)

Build a line without any vertices

Parameters:

top - the line topology
c - the contour where the line belongs

destructor

virtual ~ContourLine3D()

dummy Destructor

void computeEdgeDirection() const throw(IllegalGeometry)

Throws:

IllegalGeometry thrown when two neighboring vertices have the same position

void computeFrenetFrame() throw(IllegalGeometry)

Computes the tangent, normal and binormal vector for each vertex of a line

Throws:

IllegalGeometry thrown when two neighboring vertices have the same position

virtual void removeLine()
