Force: Dynamic Life Drawing for Animators
One line per energy or idea
- Here is our curved line with force and direction. The one line addresses one idea. The line starts somewhere, does something, and goes somewhere. This is achieved with a confident stroking of the paper with the pencil. The arrow example shows you the direction of the energy or its path. This is directional force.
- Applied force – Besides the line giving us a linear direction or path of force, it also tells use how much force is being applied upon it. This is extremely important because the force applied upon the line will be a previous directional froce. That previously directional force dictates how strong the applied force is.
The Rod of Rhythm
A rhythm is the beautiful and seamless interplay of different forces in the body that helps it stay in balance, or creates equilibrium. Rhythm exists in all living things. Your understanding of rhythm will help you create living drawings.
Gravity is the reason we have rhythmic balance in our bodies.
“The aim of every artist is to arrest motion, which is life, by artificial means and hold it fixed so that a hundred years later, when a stranger looks at it, it moves again since it is life.” – William Faulkner
