The algorithm Geom2dAPI_Interpolate scales input tangents so that they have the length of the size of the derivative of the lagrange interpolation. I have tried to skip this scaling and got the result as in the picture not_scaled.png. We can make a Boolean parameter of the algorithm that defines whether scaling is needed. |

ok, add it, i checked and saw the 3d interplote has the scale parameter, but 2d has not, |

Branch CR28594 has been created by imn. SHA-1: a658e25c2c5613dc8203f1432e08d8f53797893f Detailed log of new commits: Author: imn Date: Wed Mar 29 18:28:33 2017 +0300 0028594: Geom2dAPI_Interpolate generated curve is not the same as proe - Added boolean flag "Scale" for methods "Load" in "Geom2dAPI_Interpolate" class |
|
|
Dear Mikhail, could you please review CR28594. |
|
|
Remarks: src\Geom2dAPI\Geom2dAPI_Interpolate.hxx - Put more detailed description of parameter: boolean flag defining whether tangent vectors are to be scaled according to derivatives of lagrange interpolation. - Make modified lines shorter (up to 90-100 characters). tests\bugs\modalg_6\bug28594 - replace 'v2d' with 'smallview -2D-' to obtain less size snapshots. - the last argument '0' in 'diffimage' is extra (it is in place of output file). |

Dear Mikhail, could you please review CR28594, branch is updated according to remarks. If I understand correctly diffimage does't have extra argument ("File1 File2 tolerance blackWhite(1|0) borderFilter(1|0)") |
