One of the primary challenges I often observe among novice CG animators is grasping the concept of balance in their poses. Understanding balance is crucial for effectively conveying weight in animation. A character appearing unsteady or on the verge of falling in their pose indicates a failure to illustrate weight distribution properly.

Understanding Kinematics:

Before delving into weight and its relationship to balance, exploring various aspects of biomechanics is essential. Consider the following questions to gauge the extent to which a pose should be exaggerated and to identify the balance line within the pose:

• How flexible is the individual?
• What are the proportions of their limbs?
• What is their level of stamina?
• How does weight distribution influence balance?

An invisible line extends from the character’s head and neck to their feet, defining the balance in their poses. To assess this line in CG animation, it’s necessary to examine poses from multiple perspectives.

Gravity: 

Gravity exerts a constant downward force on the body in both static and dynamic movements. Understanding gravity and the Center of Gravity (COG) concept is vital for creating convincing poses. The COG represents the point within a body where all mass may be concentrated, and gravity acts vertically downward from this point. Consequently, the body balances around the COG, which typically aligns with the body’s geometrical center.

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.

When posing characters, keep these tips in mind:

• Avoid unnecessary movements; every motion should serve a purpose.
• Gain a thorough understanding of why each pose is created.
• Explore various possibilities to achieve clarity.
• Visualize the desired outcome before animating.
• Consider the entire pose holistically
• Ensure a balanced relationship between body parts.
• Optimize camera positioning to enhance the impact of poses.
