Lesson #12 – ARCS


-Lesson #12 – ARCS-

A simple principles that will make a huge difference! ♥ HERE THE LESSON! ENJOY 😉

-RECAP-

Let’s see another awesome principle that will enhance your animations: ARCS the invisible lines created by objects or body parts moving!

The ARCS are the PATHS OF THE MOTION!

Schermata 2019-11-09 a 22.07.40.pngBUT ALSO MORE NICE AND HARMONIC TO WATCH!

Schermata 2019-11-09 a 22.09.47.pngNever forget, while you’re animating….most of your movement should have smoothed and circular ARCS! Schermata 2018-07-06 a 20.19.57.png

We should visualize and adjust this paths for the big movements such as… an arm gesture (see the first arm movement) with a simple and circular arc…or we should follow a rounded path during a more complex movement! (see the second arm gesture)

Other examples of PATHS:

But we should also remember to check in the arcs even on little movements!Schermata 2019-11-09 a 23.10.11.png

A little HEAD TURN creates an ARC!Schermata 2019-11-09 a 23.12.31.png

Also a jaw moving creates an arc!Schermata 2018-08-16 a 23.55.56.pngThe hip during a changing weight from a leg to the other creates an arc!cw.pngFor all this situations you should keep attention to the visual path created by the movement and adjust it until you don’t reach a nice result!

We have different TOOLS to help us to check the ARCS:

  • MAYA MOTION TRAIL (very fast to use and I explained in the Tutorial #7 “How to Refine a Shot”)
  • But you can also install some scripts to show the path or use some other extra software that allow you to draw on your screen and create your arcs or manually do it using a transparent paper on your monitor!Schermata 2018-08-16 a 23.54.41.pngLet’s see other examples analyzing different actions. In a Walk Cycle we should have a smoothed arc for the HEAD and the HIP with their movement UP and DOWNSchermata 2019-11-09 a 23.41.12.png

The arms swing usually creating a FIGURE 8 ARC!Schermata 2019-11-09 a 23.43.16.png

The feet create a CIRCULAR ARC when they are in the air and a STRAIGHT LINE during the contact on the floorSchermata 2019-11-09 a 23.45.32.pngA BIG LEG MOVEMENT could create this ARCarcleg1

A small rotation movements would creates a small circular patharcleg2

Even the EYES move following an Arc! When you change the look direction it will be a very fast movement (2/3 frames) and the pose in the middle should be pose in order to create an arc!Schermata 2019-11-13 a 16.04.40

During an ACTING, where the arms do al lot of gestures, each gesture should has a nice path but is also important to ADD VARIATIONS in the arcs shapes and amplitude of the gestures, especially if we have different movements in few frames!Schermata 2019-11-13 a 16.09.37

During a “WOW” esclamation we can play with the ARC to give more flexibility to mouth and face and make it more appealing! The opening jaw movement should move up/down and left/right to create this effects!Schermata 2019-11-13 a 16.12.01

Schermata 2019-11-13 a 16.16.35A character on a swing has different arcs for the seat/hip, the head and the feet!Schermata 2019-11-13 a 16.22.40

Schermata 2019-11-13 a 16.18.13

In this example with a more powerful kick, the path of action will be more close to a straight line to give the effect of more power/speed! Schermata 2019-11-13 a 16.19.25A softer kick would have a more rounded path!Schermata 2019-11-13 a 16.19.25 2

I really hope you can now apply this principle to your animations so that you will see how important this ARCS are!
