23 | class Transform from BRepBuilderAPI inherits ModifyShape from BRepBuilderAPI | |

24 | ||

25 | ---Purpose: Geometric transformation on a shape. | |

26 | -- The transformation to be applied is defined as a | |

27 | -- gp_Trsf transformation, i.e. a transformation which does | |

28 | -- not modify the underlying geometry of shapes. | |

29 | -- The transformation is applied to: | |

30 | -- - all curves which support edges of a shape, and | |

31 | -- - all surfaces which support its faces. | |

32 | -- A Transform object provides a framework for: | |

33 | -- - defining the geometric transformation to be applied, | |

34 | -- - implementing the transformation algorithm, and | |

35 | -- - consulting the results. | |

51 | returns Transform from BRepBuilderAPI; | |

52 | ---Purpose: Constructs a framework for applying the geometric | |

53 | -- transformation T to a shape. Use the function Perform | |

54 | -- to define the shape to transform. | |

55 | ||

56 | ||

57 | Create(S: Shape from TopoDS; T: Trsf from gp; | |

58 | Copy: Boolean from Standard = Standard_False) | |

59 | ||

60 | returns Transform from BRepBuilderAPI; | |

61 | ---Purpose: Creates a transformation from the gp_Trsf <T>, and | |

62 | -- applies it to the shape <S>. If the transformation | |

63 | -- is direct and isometric (determinant = 1) and | |

64 | -- <Copy> = Standard_False, the resulting shape is | |

65 | -- <S> on which a new location has been set. | |

66 | -- Otherwise, the transformation is applied on a | |

67 | -- duplication of <S>. | |

69 | ||

70 | Perform(me: in out; S : Shape from TopoDS; | |

71 | Copy: Boolean from Standard = Standard_False) | |

72 | ||

73 | ---Purpose: pplies the geometric transformation defined at the | |

74 | -- time of construction of this framework to the shape S. | |

75 | -- - If the transformation T is direct and isometric, in | |

76 | -- other words, if the determinant of the vectorial part | |

77 | -- of T is equal to 1., and if Copy equals false (the | |

78 | -- default value), the resulting shape is the same as | |

79 | -- the original but with a new location assigned to it. | |

80 | -- - In all other cases, the transformation is applied to a duplicate of S. | |

81 | -- Use the function Shape to access the result. | |

82 | -- Note: this framework can be reused to apply the same | |

83 | -- geometric transformation to other shapes. You only | |

84 | -- need to specify them by calling the function Perform again. | |
