Animal Anatomy for Animators


Above is a short video on animal anatomy, a general introduction to how animals are put together, and how and why anatomy matters for animators.  Animal and creature animation can be technically demanding; the use of live action reference is very important as a starting point for how to bring animals and creatures to life.

IK-v-FK: Which is Best?

IK - v - FK - which is best?
One question that often confuses student animators is "IK vs FK" - Inverse Kinematics (IK) vs Forward Kinematics (FK).  The IK -v- FK debate is a bit of a techie question - it's not immediately obvious what these terms even mean, let alone how to explain which option you should choose.

IK -v- FK is really about hierarchies - usually shoulders, arms and hands.  If a character's hand controls are set to IK, then you are controlling the hands from the bottom of the arm hierarchy, from the hand control.  If you set the controls to FK, then upper arm, shoulder and body is in control of what the hands do.

In a walk cycle, you usually set arms and hands to FK, because the arms are swinging, controlled from the shoulders. But if you were to animate a sword fight, where the position of the hands is key, then you would likely choose IK.  For a bit more visual clarity, watch the short video below.

Bio Motion Walker - How to Animate a Walk

Bio Motion Walker

All student animators must learn how to animate a walk cycle, creating a successful biped walk and then giving it character and personality.

One very useful resource is the Bio Motion Walker from the Bio Motion Lab, located at York University in Toronto, Ontario.

The Bio Motion Walker allows animators to move a range of sliders showing how to make a walk cycle feel masculine or feminine, heavy or light, anxious or calm, happy or sad.  

Animators study live action, and then incorporate - and exaggerate - real life in their work . The Bio Motion Walker is a useful tool for analysing how people walk and move in different ways.
