Creating Caps to close a tubular structure

Hi All

I have created this tubular shell structure in matlab.

I would like to create caps to close the end

[F,V] = surf2patch(x_All,y_All,z_All,'triangles');

h = patch('faces',F,'vertices',V);

set(h,'FaceColor',[0.5 0.5 0.8],'EdgeColor','k');

I cannot run your code.

Adapt this to your cylinder:

D = 10;
[X,Y,Z] = cylinder(D);

r = D;
ang = linspace(0, 2*pi);
xcirc = r*cos(ang);
ycirc = r*sin(ang);
zcirc = ones(size(ang))*max(Z(:));

figure
surf(X, Y, Z)
hold on
patch(xcirc, ycirc, zcirc, 'r')
hold off
grid on

This creates a red ‘top’ to the cylinder. To cap it on the other end, duplicate the patch call, however substituting:

zcirc = ones(size(ang))*min(Z(:));

in the second call.

Thanks @Star Strider, that worked great

It sounds like you want isocaps. See this documentation page for more information.

Hey Steven, thanks for your help. Yes, I was originally going to use that but couldnt figure out how to calculate the V part
