|Target Version||7.4.0||Fixed in Version||7.4.0|
|Summary||0028016: Different result of intersection algorithm between two plane-like cones on Windows and Linux platform|
|Description||The quotation of the message 0027431:0059293.|
There is different behavior on Windows and Linux platform even on the current MASTER. Namely, set of IntPatch_Point(s) (vertices) is different. E.g. we have three vertices on both Windows and Linux. However, two vertices are matched on the Windows. On the Linux, the distance between them is ~ 1.0e-4 (square distance = 1.16190303248061e-08). Small second curve is built between these vertices.
The fix (for issue #27431) does not touch the algorithm of vertex computation. Therefore, the problem exists on the MASTER. But it is hidden by something.
New algorithm (applied in the fix) is forced to use vertices (as the point, which marks singularity). Therefore, described bug has been naked.
The issue 0000565 was created because the intersector did not return any result in case of trimmed cones. Now, it returns the result. But this result is different on Windows and Linux. Therefore, the problem described in the issue 0000565 is not reproduced on the fix.
