How to created a bouncing ball animation
In this section I am going to talk about animation with bouncing balls, every different type of ball has a different way of bouncing due to their weight, size and what material they are made of. I am going to start with a tennis ball.
Step 1: open “Maya 2012” production by “Autodesk”
Step 3: create a sphere and plane in “Maya 2012” using create surface tool
Step 4: click on box located next to the key, it is called animation preferences open it up. Change the playback speed to real time, which is 24 frames a seconds (the more frames there are the smother the animation looks)
Step 5: click on the first frame and then click on animation and set key frame. We do to create the first scene
Step 6: go to frame 7 and move the ball diagonally down and place it just above the plane but not on top of it, set a key frame.
The frames before 7 will now be filled in with the ball in a different place thus creating the animation.
Step 7: Go the frame 8 and continue to move the ball down so it touches the place and then squash it make it flatter and wider. This is because tennis balls are soft.
Step 8: Copy frame 7 and paste it into frame 9, after move the ball straight forward, the reason for frame 7 and 9 is so the ball doesn’t change before it hits the ground.
Step 9: go to frame 14 and move the ball diagonally higher as show below. The reason for this is the ball loses power after each bounce. After this go to frame 17 and repeat what you did with frames 7, 8 and 9. Repeat the whole process until frame 26 when the bouncing has ended. Remember as the bounce gets lower the ball gets to the ground faster (note you may have to create more frames into order to make slight correction as the animation may go wrong.
Your animation should look like this
Now I am going to create another bouncing ball, but instead of a tennis ball I will use a bowling ball.
Step 1: start like you did with the tennis ball but look at a bowling ball video instead http://www.youtube.com/watch?v=8eejc0p7nCM you can see that because of the size and material of a bowling ball, it is a lot heavy and doesn’t bounce as much, also it doesn’t squash because they made of a combination of plastic, reactive resin and urethane.
Step 2: For this animation set the frame range to 70, on frame 1 place the sphere in the middle of the plane and create a key frame.
Step 3: go to frame 15 and place the ball just on top of the plane, and set a key frame because of the materials there is no squash.
Step 4: go onto frame 22 and place the ball above the plane as shown below and set a key frame
Step 5: go to frame 35 and place the ball on top of the place and set a key frame, (notice how the frame distance get smaller)
Step 6: go to frame 40 and place the ball as shown below and set a key frame.
Step 7: go to frame 49 and place the ball on top of the plane and set a key frame.
Step 8: got to frame 70 and set a key frame and the animation is finished
It should look like this
Note you can correct your animation if it looks like it hovers a bit, going back onto graph editor (located in Window-animation editor) and modifying the lines in the different axis tabs.
Learning out come
By doing this, I have learned that animation isn’t as easy as it looks, as I struggle making a ball bouncing animation which I imagined would be one of the basics. When I started the tennis ball animation I didn’t include a squash, so the animation didn’t look like a bouncing tennis ball, but looked like it was being controled after I put the squash in, because I didn’t include the key frames beside it, the ball ended up looking completely different at the end. I found the blowing ball animation a lot easier though as it wasn’t as complicated because it didn’t bounce a lot and it didn’t squash.
