Constructor & Destructor Documentation

template<class T> Multivac::CSetOfPoints< T >::CSetOfPoints (  Curve< T > &  InitialFront  )

Constructor. Sets the front equal to 'InitialFront'. Parameters: InitialFront  the initial front.

template<class T> Multivac::CSetOfPoints< T >::CSetOfPoints (  string  InitialFrontFile, int  orientation, bool  origin_out_ )

Main constructor. Reads the file defining the front. Parameters: InitialFrontFile  file that stores points defining the front. orientation  orientation of the front: -1 if the orientation is unknown, 0 if points are stored in the trigonometrical orientation and 1 if they are stored in the reverse orientation. origin_out_  position of the bottom left corner of the mesh. 'true' if the corner is outside the front, 'false' if it is inside.

Member Function Documentation

template<class T> T Multivac::CSetOfPoints< T >::GetDistance (  T  x, T  y )  [inline, virtual]

Returns the distance from a given point to the circle. Parameters: x  point abscissa. y  point ordinate. Returns: Distance from (x, y) to the circle. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CSetOfPoints< T >::GetProjectionOnMesh (  T &  x, T &  y, CMesh< T > &  Mesh )  [virtual]

Returns the closest mesh-point of the projection of (x, y) on the curve. Let A = (x, y). Let B be the projection of A on the curve. Let C be the closest point to B that is on the mesh (included its vertices). On exit, C is returned through x and y: C = (x, y). Parameters: x  first coordinate of the point to be projected. y  second coordinate of the point to be projected. Mesh  mesh. Warning: Undefined function. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CSetOfPoints< T >::Save (  string  CurveFile  )  const [virtual]

Saves the circle. Parameters: CurveFile  the descriptor of the file where data are saved. Warning: This function doesn't save any point because the circle is analytically defined. Implements Multivac::CInitialCurve< T >.

template<class T> void Multivac::CSetOfPoints< T >::SetDistances (  CMesh< T > &  Mesh, CLevelSet< T > &  Phi )  [virtual]

Updates the level set function Phi by setting distances to the circle. Parameters: Mesh  orthogonal mesh. Phi  level set function defined on an orthogonal mesh. Exceptions: Seldon::WrongCol  attempt to reach a wrong column number. Seldon::WrongRow  attempt to reach a wrong row number. Implements Multivac::CInitialCurve< T >.
