I have a 3D spherical graph that draws a sphere (Earth) and points along the sphere. However, when I zoom in on the sphere, the edges of the plot window cut off the sides of the image. See the screenshots below:
I've tried changing the camera perspective, setting the axes so they are outside of the window (so the sphere would intersect with the boundaries of the axis when it is outside of the window, etc.) but nothing has worked so far. In essence, I need some way to create a spherical enviorment so when I zoom in on the sphere, the walls of the plot consisently or spherically remove the textures around the sphere, rather than making straight, flat cuts through the sphere.
The code for the sphere generation is shown below:
[X,Y,Z] = ellipsoid(0, 0, 0, rE, rE, rE, 100);
globe = surf(X,Y,Z);
Please let me know if you have any ideas! Thank you so much!

Oh, good. What does the zoomed in figure look like with that parameter changed (just curious)?

This doesn't work if you want to be able to interactively zoom in on a region, but if you have in mind a specific range of X, Y, Z that you want to examine, something like this might work.
Also note that your example code doesn't draw the pretty globe with continents and oceans, just a ball.
rE = 6.378e6; % meters
[X,Y,Z] = ellipsoid(0, 0, 0, rE, rE, rE, 100);
globe = surf(X,Y,Z);
axis equal
xlabel 'X'
ylabel 'Y'
zlabel 'Z'
range = 1000*5280*0.3048; % 1000 miles converted to meters
idx = (X < -range) & (Y < -range) & (Z > range);
X(~idx) = nan;
Y(~idx) = nan;
Z(~idx) = nan;
surf(X, Y, Z)
axis equal
