Adding a full rotation

Next, we add a 360-degree rotation around the x-axis:

At frame 0:
- rotate by 10 degrees vertically
- rotate by 10 degrees horizontally
- zoom by a factor of 0.6

From frame 0 to frame 90 rotate by 180 degrees vertically

Clicking the “Run” button again now renders a movie with 90 frames. Starting from the initial orientation which we adjusted in the last paragraph, the cornea is now rotated around (the view’s) x-axis. Note that transformations (here rotations) are applied in the order they appear in the text. First, the 10-degree rotations are applied, and then the cornea is rotated around the (already rotated) x-axis. If we wanted the cornea to rotate around the original x-axis, we needed to reverse the order of the transformations:

From frame 0 to frame 90 rotate by 180 degrees vertically

At frame 0:
- rotate by 10 degrees vertically
- rotate by 10 degrees horizontally
- zoom by a factor of 0.6
