Hello everyone,
I have the following code showing a square. What I have to do to get it filled?
Many thanks!
figure
X = [0,0,1,1; 1,0,1,1; 1,0,1,1; 1,0,1,0];
Y = [0,0,0,1; 0,1,1,1; 0,1,1,1; 0,1,1,1];
Z = [1,1,1,1; 1,1,1,1; 1,1,1,1; 1,1,1,1];
C=[1,1,1,1;1,1,1,1;1,1,1,1;1,1,1,1];
fill3(X,Y,Z,C);

your code is confusing because your are not defining 1 square, you are defining 4 squares
2nd
it is already filled, let me explain:
when you generate a surface with commands like fill3 patch surf surface
all you have to do is to collect the handle, for instance
h1=fill3(X,Y,Z,C)
4x1 Patch array:
Patch
Patch
Patch
Patch
as you can see, with your current X Y Z you have 4 overlapped patches.
When attempting to change parameters like transparency and face colour, it can get confusing, so let's simplify
X = [0,1,1,0];
Y = [0,0,1,1];
Z = [1,1,1,1];
h2=fill3(X,Y,Z,[0 0 1])
note that the order of introduction of points matters, if you jump to an opposite vertex the square will look like a bow tie.
To change color and transparency all you have to write in example:
h2.FaceColor=[1 0 0]
h2.FaceAlpha=0.3
if you find these lines useful would you please mark my answer as Accepted Answer?

Could you please tell how to extract mesh data from the handle h1=fill3(X,Y,Z,C) and export it in the text file ? I need the coordinates of the points on the surface created by fill3 command. Thank you very much!
