31 | ---Purpose: Calculates all the IntersectionPoints | |

32 | -- and IntersectionSegments between an implicit curve | |

35 | -- The results of the intersection are stored in the | |

36 | -- Intersection class from IntRes2d. | |

37 | -- The parametrised curve has to be bounded (the domain | |

38 | -- of this curve must verify HasFirstPoint returns True | |

39 | -- and HasLastPoint returns True). | |
