17 | class SurfCurvEvolRadInv from BRepBlend | |

18 | ||

19 | inherits SurfCurvFuncInv from Blend | |

20 | ||

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

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

23 | -- surface. | |

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

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

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

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

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

29 | -- the surface. | |

30 | ||

31 | uses | |

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

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

83 | ||

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

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

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

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

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