Exception classes

class EmptyLine: public Exception

Exception when creating a 3D contour line without any vertices

class IllegalGeometry: public Exception

Exception when two consecutive vertices have the same position which makes the definition of normal vector impossible

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

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

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)

ContourLine3D(const ContourLine3D *l, Contour3D *c)

Copy constructor

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