22 | class SurfCurvEvolRadInv from BRepBlend | |

23 | ||

24 | inherits SurfCurvFuncInv from Blend | |

25 | ||

26 | ---Purpose: Class used to compute a solution of the | |

27 | -- surfRstConstRad problem on a done restriction of the | |

28 | -- surface. | |

29 | -- The vector <X> used in Value, Values and Derivatives | |

30 | -- methods has to be the vector of the parametric | |

31 | -- coordinates wguide, wcurv, wrst where wguide is the | |

32 | -- parameter on the guide line, wcurv is the parameter on | |

33 | -- the curve, wrst is the parameter on the restriction on | |

34 | -- the surface. | |

35 | ||

36 | uses | |

61 | ---Purpose: computes the values <F> of the Functions for the | |

62 | -- variable <X>. | |

63 | -- Returns True if the computation was done successfully, | |

64 | -- False otherwise. | |

65 | returns Boolean from Standard; | |

66 | ||

68 | ---Purpose: returns the values <D> of the derivatives for the | |

69 | -- variable <X>. | |

70 | -- Returns True if the computation was done successfully, | |

71 | -- False otherwise. | |

72 | returns Boolean from Standard; | |

73 | ||

74 | Values(me: in out; X: Vector; F: out Vector; D: out Matrix) | |

85 | ---Purpose: Returns in the vector Tolerance the parametric tolerance | |

86 | -- for each of the 3 variables; | |

87 | -- Tol is the tolerance used in 3d space. | |

88 | ||

89 | GetBounds(me; InfBound,SupBound: out Vector from math); | |

90 | ---Purpose: Returns in the vector InfBound the lowest values allowed | |

91 | -- for each of the 3 variables. | |

92 | -- Returns in the vector SupBound the greatest values allowed | |

93 | -- for each of the 3 variables. | |

94 | ||

95 | IsSolution(me: in out; Sol: Vector from math; Tol: Real from Standard) | |

96 | ---Purpose: Returns Standard_True if Sol is a zero of the function. | |

97 | -- Tol is the tolerance used in 3d space. | |

98 | returns Boolean from Standard; | |
