Lesson: Biomechanics and Balance

This is part of a series I have started of lessons from my class lectures. I will choose a topic from time to time to expand on. If you have ideas for a topic please contact me with topics.

Understanding Kinematics: You must ask yourself these questions to understand how far to push a pose and find the balance line within the pose.

  • How limber is the individual?
  • How long are limbs?
  • Stamina?
  • Weight and Balance?

There is an invisible line that runs from your character's head and neck to the feet.  This plumb line defines the balance in your poses. To check this line in CG you must look at your poses from all angles.TIP5

Gravity:

  • Gravity is constantly affecting the body in both static and dynamic movement.
  • Gravitational downward pull on an object.
  • Understanding gravity, the COG (Center of Gravity) will help you create solid poses.

COG and Balance:

  • The COG is the point of a body at which all the mass may be concentrated.
  • The force of gravity acts vertically downwards from this point.
  • Basically, the body balances around this point.
  • The COG of a body is at its geometrical center.

Some tips for posing:

  • Don’t move anything unless it’s for a purpose.
  • Don’t move anything unless it’s for a purpose.
  • Don’t create a pose without knowing why.
  • Do get the best animation poses by exploring all avenues.
  • Do picture in your head what it is you’re animating.
  • Do think in terms of creating an entire pose, not just the head or eyes, etc.
  • Do keep a balanced relation of one part of the character's pose to the other.
  • Do stage the camera for the most effective poses.

OpenToonz

Animation software OpenToonz, which is used by many studios, most notably Japanese Studio Ghibli has been made open source and available for absolutely FREE! And you can also download the same tools that Studio Ghibli used for their process!

“With one announcement, the animation software game may have changed forever. Toonz, the software used by Studio Ghibli to produce films like The Tale of the Princess Kaguya, Howl’s Moving Castle, Ponyo and The Wind Rises, will be made free and open source to the animation community beginning March 26, 2016. The deal, which could have a potentially profound impact on the animation industry, was made possible after Japanese publisher Dwango acquired the Toonz software from Italian tech company Digital Video, which has been producing the animation package since 1993. Ghibli has been using Toonz since the production of Princess Mononoke, and the new OpenToonz is dubbed “Toonz Ghibli Edition” because of all the custom-features that Toonz has developed over the years for the legendary Japanese studio.  Atsushi Okui, executive imaging director at Studio Ghibli, explained that they initially chose Toonz back in 1995 “in order to continue producing theater-quality animation without additional stress,” and a desire for software that had “the ability to combine the hand-drawn animation with the digitally painted ones seamlessly.” 

However, Toonz is not exclusive to Ghibli and is used by plenty of other studios, including Rough Draft, which produced Matt Groening’s Futurama with it, and Folimage, which used it for its recent feature, Phantom Boy.

Simon Hayes provides a peak into using Studio Ghibli’s OpenToonz Plastic software feature to create cutout 2D characters animated using bones and joints. OptenToonz plastic feature is similar to After Effects’ puppet pin tools, however, OptenToonz is a bones or joint based system that surpasses Ae’s rudimentary puppet pins. For one, a bone and joint system will inherently have a hierarchy to them, making them ideal for character rigging and animation. A skeletal system is also the foundation for more advanced systems such as constraints and IK (Inverse Kinematics). Here, Simon Hayes lays out the basics and steps for easily creating a 2D cutout character using the Plastic tool.


How To Draw Adventure Time -Pendleton Ward

dc982f42fb0e1b5eb53064e0530faa20

Adventure Time's Pendleton Ward made this extensive guide to the rules for drawing Finn and Jake, even while encouraging people to break most of them. The Style guide for Adventure Time allows anyone drawing Finn to occasionally break rules of the style guide itself (and physics) if it allows for a better animation on the character. Style guides usually make it online after being distributed by the show itself in some sort of blog or in an “Art of” book. Occasionally, animators who worked on a show will let the style guide go after they conclude their work on it.
