Member Function Documentation

template<class T, int N> void PLib::NurbsCurveArray< T, N >::init (  NurbsCurve< T, N > *  ca, int  size )

Initialize the array of curves with a vector of nurbs curve. Parameters: ca  a pointer to a vector of NURBS curve size  the size of the array Author: Philippe Lavoie Date: 24 January 1997

template<class T, int N> int PLib::NurbsCurveArray< T, N >::read (  const char *  filename  )

Reads a NurbsCurveArray from a file. Parameters: filename  the filename to read the curve array from Returns: 0 if an error occurs, 1 otherwise Author: Philippe Lavoie Date: 24 January 1997

template<class T, int N> void PLib::NurbsCurveArray< T, N >::resize (  int  size  )  [virtual]

Resize the NurbsCurveArray. Parameters: size  the new size Author: Philippe Lavoie Date: 24 January 1997

template<class T, int N> int PLib::NurbsCurveArray< T, N >::write (  const char *  filename  )

Writes a NurbsCurveArray from a file. Parameters: filename  --> the filename to read the curve array from Returns: 0 if an error occurs, 1 otherwise Author: Philippe Lavoie Date: 24 January 1997

template<class T, int N> int PLib::NurbsCurveArray< T, N >::writePS (  const char *  filename, int  cp = 0, T  magFact = T(-1), T  dash = T(5), bool  bOpen = true )  const

Writes a post-script file representing an array of curves. Parameters: filename  the file to write the postscript file to cp  a flag indicating if the control points should be drawn, 0 = no and 1 = yes magFact  a magnification factor, the 2D point of the control points will be magnified by this value. The size is measured in postscript points. If the magFact is set to a value smaller or equal to 0, than the program will try to guess a magnification factor such that the curve is large enough to fill the page. dash  the size of the dash in postscript points . A size smaller or equal to 0 indicates that the line joining the control points is plain. Returns: 0 if an error occurs, 1 otherwise Warning: If the weights of the curve are not all at 1, the result might not be representative of the true NURBS curve. Author: Philippe Lavoie Date: 7 October 1998

template<class T, int N> int PLib::NurbsCurveArray< T, N >::writePSp (  const char *  filename, const Vector< Point_nD< T, N > > &  points, const Vector< Point_nD< T, N > > &  vectors, int  cp = 0, T  magFact = 0.0, T  dash = 5.0, bool  bOpen = true )  const

Writes a post-script file representing the array of curves. Writes the array of curves in the postscript format to a file, it also draws the points defined in $points$ with their associated vectors if $vector$ is used. Parameters: filename  the file to write the postscript file to points  draws these additional points as empty circles vectors  specify a vector associated with the points (this can be an empty vector) cp  a flag indicating if the control points should be drawn, 0 = no and 1 = yes magFact  a magnification factor, the 2D point of the control points will be magnified by this value. The size is measured in postscript points. If the magFact is set to a value smaller or equal to 0, than the program will try to guess a magnification factor such that the curve is large enough to fill the page. dash  the size of the dash in postscript points . A size smaller or equal to 0 indicates that the line joining the control points is plain. Returns: 0 if an error occurs, 1 otherwise Warning: If the weights of the curve are not all at 1, the result might not be representative of the true NURBS curve. If vectors is used, then it must be of the same size as points. If a vector element is (0,0,0) it will not be drawn. Author: Philippe Lavoie Date: 7 October 1998
