I have surface data stored in faces and vertices. How to extract data in a slice (or 2D plane) from this Faces and vertices data?

Use interp2

[x,y,z] = peaks(20);
x1 = linspace(min(x(:)),max(x(:)),20);
y1 = sin(x1);
z1 = interp2(x,y,z,x1,y1);
surf(x,y,z,'facecolor','none')
line(x1,y1,z1,'linew',2)
axis vis3d

Thanks a lot darova for the quick response.

However, this does not work for my case.

My input data is in the form of Faces and Vertices which is generated using isosurface command.

With Faces and Vertices and as input, is there a way to extract the data in a 2D plane?

[darova]

Can you convert your data into surface? Use griddata

[Sachin Shinde]

griddata doesn't seem to be useful.

[darova]

It's, you should try it

[Sachin Shinde]

Is there a way to convert Faces and Vertices data to 3D grid data?

[darova]

please see help: griddata

[Sachin Shinde]

Thanks, but griddata does not take Faces and Vertices as input.

[darova]

It takes vertices only. It doesn't need faces

[Sachin Shinde]

Thanks a lot. I will check that.

Hi

I have the attached data.

I don't know how to prceed with 'griddata'.

could you please take a look?

Thanks.
