Plot shell boundary in 3D

I want to plot a shell layer structure in 3D space. I have three-dimensional coordinate vectors x(:,:,:), y(:,:,:), z(:,:,:) and a data vector V(:,:,:) that has nonzero values at the shell locations and is zero elsewhere. The closest image that I could find similar to what I want is this:

How can I do this? Let's say, I only need to plot the middle layer. The closest that I could do is to use:

s=scatter3(x,y,z,1,V)

But this creates a plot of scattered data points. Is there a way to get Matlab to create a surface out of the scatter points?

Hi Hadi,

I understand from your question that you want a better graph plot than scatter plot and preferably something continuous.

I guess the surface plot function should do the trick for you. Try implementing

surf

Sample Snippet :

[X,Y] = meshgrid(1:0.5:10,1:20);
Z = sin(X) + cos(Y);
surf(X,Y,Z)

You might find the documentation very useful.
