Hello,
I have a question that has been asked a few times on different ways but I have not been able to understand it.
My data:
I have a tooth as in the upload, which is the result of a mean calculation from other teeth. As you can see in the picture, it is fragmented as a result from the calculation.
I would like to make an interpolation, so that these fractures are filled.
As I have understood, I should use griddata or scatteredInterpolant, both having a variable v which I don't understand. Can someone explain to me or show me in the right direction, how can I understand this variable v, so that next time, when I have to interpolate something (which will happen), I can do it on my own?
Of course I would be very happy if someone gave me the solution for this explicit example, but I honestly want to understand it.
Thank you :)

Thank you very much. I will look into it soon and then come back with my results.
I started with STL, yes. But after a few steps, the connectivity is of no use anymore, since the points don't correspond anymore.
