Animation of human body

Participants    Young-in, Jessica, Vinay

Problem

Animate the human body, obtaining realistic interactive rendering.

Rendering will be done on an SGI Onyx2.

Data flow

Assumptions and limitations

• Skeletal model is rigid, with movements allowed only at joints
• Inverse kinematics is constrained enough to obtain realistic output
• All other deformable parts are defined with respect to the bones
• Database of intermediate positions is to be constructed

Different issues:

• Input animation script, validation
• State space description of human activity
• transformation matrices, degrees of freedom
• interpolation, arc length parameterizations
• Consistent inverse kinematics
• Speedup techniques like view frustum, transfer function properties, animation properties
• Linking deformation surfaces to skeleton
• Collision detection
• Saving, compressing a fly-through
