Differents results between MacOS et Windows 10 #27

Closed Toon34 closed 3 years ago

Toon34 commented 5 years ago

Hello !

I use MacOS X Mojave 10.14.4 and Windows 10 up to date. In my case, i need to use ACVD for deploy a complex deformable sphere. I search in this github repository but i did not find anything... Has anyone ever encountered any differences?

With the same input...

Windows ouput :

Mesh with 3040 polygons, 1522 points, 4560 edges Bounding Box: [94.6748, 63.8625, -75.726] [101.292, 70.7261, -66.4477] The mesh is made only of 3040 triangles 0 non-manifold edges and 0 boundary edges The mesh has 1 connected components Valences entropy: 1.64355 0 disconnected vertices, 1522 connected vertices 46.6491 percent of irregular vertices Mesh geometry qualitity: AngleMin=24.1465 AverageMinAngle=46.4177 Qmin=0.437835 Qav=0.827767 P30=0.372807

Hi, sorry, I just saw your comment. Maybe this comes fom the random initialization. Let me think about it...

I just filled an issue related to random_shuffle, maybe it will be the opportunity to kill two birds with one stone :)

I also arrived to the conclusion that the unspecified random generator may result to unreproducible cases !
