I am plotting a sphere (world) that later I rotate using the built-in function view. This works well and allows to rotate the sphere the way I want in a loop to save individual frames. But the problem is that at each rotation, the size of the sphere changes (see animation attached). My ultimate goal is to create a nice animation but the changing size of the sphere is annoying.

My question then is: Is there a way that I can rotate the camera view but keep the same sphere size in each frame? Perhaps, another function similar to view? or another kind of workaround?

This is how I am creating the sphere:

I = imread('myimage.png');
[x,y,z] = sphere(359);
surface(x,y,z, 'FaceColor','texturemap','EdgeColor','none','Cdata',flipud(I))
view(3)
daspect([1 1 1])

After that, I plot the data that I want.

I have also tried using:

set(gca,'Position',[0 0 1 1])

and/or:

axis tight

and it does not work for my purpose.

Thanks!

Tim's comment is the answer (Tim, consider moving it to the answers section).

Demo:

[x,y,z] = sphere(359);
surface(x,y,z, 'FaceColor','texturemap','EdgeColor','none')
view(3)
axis vis3d
grid on
xlabel('x'); ylabel('y'); zlabel('z')
rotate3d on
