interpolating from a 3D structure

Hi all

I have three vectors, named X,Y, and Z, related to the coordinates of a structure and also a vector named W showing the displacement of each node. My structure using scatter3 is like this. I'm gonna interpolate it to obtain an 3D image. How should I interpolate such an irregular shape?

Hi @Erfanandoaut,

I understand that you want to perform interpolation on a 3-D dataset of scattered data. For this purpose you can use the "scatteredInterpolant" function in MATLAB. You can use the below command to open an example of 3-D interpolation using the "scatteredInterpolant" function.

openExample('matlab/ScatteredInterp3DExample')

We can also select the appropriate interpolation method required using this function.

For more information on "scatteredInterpolant" function, please refer to the documentation link below.

Hope this helps!
