Difference of behavior in cutMesh

[francois]

Hello,

I noticed a weird difference of behavior between the stable 4.6.0 and a recent 4.6.1 build that Denis sent me (Ubuntu16).

Consider the following code:

Code: Select all

mesh = aims.read("/home/ftadel/test_cutmesh/test_mesh.gii")
testcut = aims.AimsSurfaceTriangle()
border = aims.AimsTimeSurface(2)
aims.SurfaceManip.cutMesh(mesh, [0.5225450036568081, 0.6545940900566004, -0.5463087921828437, -68.96895971837064], testcut, border)
print testcut.vertex().size()

And the example file:
https://www.dropbox.com/s/gqrevq0a2e8fi ... h.gii?dl=0

With 4.6.0, I get a correct mesh (755 vertices).
With 4.6.1, I get an empty mesh (0 vertices).

Is there anything that changed in this function or is this a bug?
Is there a way to get the previous output with the current function?

Thanks
François

Any update on this topic?
Should I start looking for another solution?

Hi François,
I get the same behavior so I can reproduce the problem. It's obviously a bug, probably in the way the function is called since the algorithm has not changed and is still working inside anatomist. I'll investigate.

Thanks

Btw, I am "subscribed" to the topic but I don't receive the new posts by email.
I checked the preferences of my account and it all seems to indicate that I should receive notifications by email.
So I just keep the page open and refresh it from time to time... Is there anything I'm not doing correctly?

I have fixed the problem but you will need a new compiled package. I'll do that next week.

Otherwise the forum notification seems to be broken, I also don't receive any email when new posts or answers are in the forum. I don't know why, and I'm afraid I really have no time to investigate right now.

Ok thanks!
I'll wait for your update instead of trying to recode cutMesh on my end then.
(I will need both the Ubuntu16 and Mandriva2008 versions... sorry for the added work)
