Bridging-Angle not optimal

Version

1.30 release candidate vs. 1.31.2

Operating system type + version

windows 7 up to date

Behavior

Bridging in the latests release seems to get wrong. See pics. Angle set in the Print-Settings-Infill-Tab is used.

STL/Config (.ZIP) where problem occurs

Used the same given profiles in both versions from Prusa3D: 0,2mm NORMAL; Prusa PET; Original MK2 ColorPrint

I think it's wrong in both pictures. Shouldn't Slic3r try to keep bridges as short as possible? Something like in the lower picture but rotated by 90°?

[mgineer85]

Hm,... if it would be rotated by 90° it would try to connect to the perimeters just created and still hot. Believe that would not be as good as in the first picture, but I'm just guessing.

[CReimer]

Ahh yes. That makes sense.

The bridging has been broken, when I tried to fix the bridging for close regions. Now the bridging should work for both single and multiple touching regions.

[mgineer85]

thank you for your effort in this (single+multiple), will try again

[mgineer85]

Thank you for building a new release and adding further information on how to build, I didn't get it right.
Just tried the new version, looks better now, but still not perfect in every case.

Bridges in different isles get the same angle though not touching and separated by perimeters.

Would you please attach the models? Thanks.

Uploading ZIPs with Firefox to github seems to be broken, otherwise I would have already.
Uploaded the models externally: https://oc.groene.de/index.php/s/c5kl7htxKlBesTE

Thanks for very good test cases. For the current code the bridging regions are connected. I am on a good way to fix it.
