3D Rotating Ring - Page 11

The Final Round

OK? Let's go to the final round, now. There is only a thing you have to understand, then it will be very easy: when a ring, or a coin, makes a spin around its axis, we begin seeing the ring by face, then we see a smaller part of it, 'til it reaches half of the way and we see it from the side. Then, it begins the second half of the spin, so initially we see a little part of it, then a greater part, finally again its face (its second face, by the way). Going back to the ring, the 22th frame will be equal to the 20th, only flipped horizontally, the 23th will be equal to the 19th, and so on...

At the end, we'll have the 41th frame equal to the first, flipped horizontally (think of the 2 faces of a coin)

To obtain this result with our movie, we'll act this way: select the first frame of the movie, and Copy it (Ctrl+c). Then, put a keyframe (F6) on frame 41 and paste in place (Ctrl+Shift+v) what you copied. Finally, choose Modify > Transform > Flip Horizontal

What you have now is the mirror image of the first frame:

Repeat the process with frames 2-40, 3-39, 4-38, and so on, and finally..."WE DID IT!" We have our beloved rotating ring!

Have a good day an take it easy! Bye!
