In my animation I used some principles of traditional animation to help my animation seem more realistic. These principles are:

 

• Timing and Motion - I used this to show that the bowling ball had a larger mass than the bowling pins, so it could knock them back.

​

• Staging - It is clear that this is a bowling lane with bowling pins and bowling balls.

​

• Overlapping Action - I used overlapping when the pins were getting hit back by the ball as the ball still travelled down the lane. Also multple collisions of bowling pins were simultaneously occuring.

​

• Pose-to-Pose Action - I used this when determining the route for the ball. I chose a starting point and an endpoint and the program created the frames in between.

​

• Secondary Action - There are multiple cases of secondary action in this animation. All of the pins getting hit back are results of the bowling balls hitting a pin. Also, the score at the end showing the spare is also a secondary action.
