unfold

[micheus]

Ok. While I wait you try that change in the code - which will make the process easier than you are doing now - let's keep thinking about this different way to open the mesh you have been trying to make me understand...

Back to the "egg" example, the edge approach seems to not be the case for it, but the current way used to unfold in Wings3D (like in the video).

So, thinking in something less obvious, when opening a mesh...
Do you already have something in real life you made in metal using the current approach?

Since the cloth approach seems to not really be the way to reach the result you expect, that could be a way I visualise the 3D model, the opened mesh and the object assembled.

By selecting the edge to produce the cut and unfold faces, which situation of those would you expect as result?

unfolding and - if possible - smoothing out vertices as suggested in #post12 is most probably the neatest way to go in this case. the rest is just-- cosmetics*?

That reference is about to deform an object while the unfold is about to open a mesh of an object. Again we are talking about two things.

I can imagine to add a new way to open the UV mesh as something useful somehow; But, deform the object making assumptions about where to smooth and in a non "physical" way means to create a targeted tool - not useful for the current context of CG apps which uses the cloth simulation for that - even the material not really been a fabric (it can be rubber or something more rigid by controlling some parameters involved in the algorithm).

I cant say I would have time (very sparse) to work in something like this (it may be also beyond my ability ).
