1/4
CA1101 Principles of 2D Animation
Instructor: Krishna M. Sadasivam
Flour Sack Animation Project
The flour sack animation is an excellent learning platform for
understandingnatural deformations in movement and dealing with the
inherent limitations.
This project serves as a real training ground for understanding
forces,
deformation, and fundamental movement.
Using the half-filled flour sack will allow you to practice
natural movement
without having to deal with the extreme complexities of a person
or an animal.
Your assignment:
The flour sack must jump over a trap (provided by the
instructor). The flour sack
must:
1) anticipate the jump
2) jump
3) land and react with an emotion.
Due Week 5:
Your Flour Sack animation is due at the beginning of Week 5.
