| Summary | 0031172: Modeling Algorithms - Unexpected result of BRepTools::OuterWire() | ||||
| Description | The attached face contains three wires touching each other at vertices. As a result of BRepTools::OuterWire(), the incorrect wire is returned (the tool returns one of the circles instead of the outer contour). | ||||
| Steps To Reproduce | The test case named bug31172 | ||||
| Tags | No tags attached. | ||||
| Test case number | bugs/modalg_7/bug31172 | ||||

In BRepTools::OuterWire(), lines 620-623, there is an 'if' statement comparing double values like follows: if ((umin <= UMin) && (umax >= UMax) && (vmin <= VMin) && (vmax >= VMax)) ... It is likely a good idea to use at least PConfusion() instead of naive equality checks which do not work for the provided test case. |

Sergey (SZY), please consider this simple bug for fixing. |

Looks good. http://jenkins-test-12.nnov.opencascade.com/view/CR31172-master-aavtamon/view/COMPARE/ |

Incorrect treatment of upper bounds. The correct code must look like this:
if (((umin - UMin) <= Precision::PConfusion()) &&
((umax - UMax) >= -Precision::PConfusion()) &&
((vmin - VMin) <= Precision::PConfusion()) &&
((vmax - VMax) >= -Precision::PConfusion())) {

Thank you for the remark, I have applied it. The new test results: http://jenkins-test-12.nnov.opencascade.com/view/CR31172-master-aavtamon/view/COMPARE/job/CR31172-master-aavtamon-OCCT-Debian80-64-opt-test-compare/ |

Too many differences in images. I see that you compared with the reference at OCCT-751dev. It is incorrect. You need to compare with the branch that is direct parent of yours. |

I retested the branch: http://jenkins-test-12.nnov.opencascade.com/view/CR31172-master-aavtamon/view/COMPARE/ |
