Skeleton and Joint Hierarchy

Joint Placement

• Anatomical Accuracy: Place joints following anatomical structure
• Deformation Considerations: Position joints for optimal deformation
• Joint Orientation: Orient joints for proper rotation axes
• Joint Hierarchy: Create logical parent-child relationships
• Naming Conventions: Use consistent, descriptive joint names
• Scale and Proportions: Maintain proper scale and proportions

Joint Types

• Ball Joints: 3 degrees of freedom (shoulder, hip)
• Hinge Joints: 1 degree of freedom (elbow, knee)
• Universal Joints: 2 degrees of freedom (wrist, ankle)
• Root Joint: Base of the skeleton hierarchy
• End Joints: End of joint chains (fingertips, toes)
