Biomechanical Analysis from Motion Capture

A 3D pipeline that shows power distribution through the human body.

What the Pipeline Computes

The pipeline ingests standard motion capture data and computes across the full skeletal hierarchy. The output spans four analysis domains, each visualized as an independent interactive layer.

Skeletal Loading

Forces propagate through the skeletal chain through the spine and out to the extremities.

Fascial Force Transmission

Twelve myofascial meridians are evaluated for connective tissue stress. Each meridian is rendered as a transparent skinned mesh with per-frame color animation driven by the underlying joint kinetics.

Muscular Activation

Over 200 individually modeled muscles are mapped to their corresponding joint actions and visualized by activation intensity across the movement.

Performance Metrics

Sequential joint activation and endpoint performance metrics — speed, efficiency, and energy output

Computation & Rendering

Applications

This pipeline was developed for human movement analysis but the underlying approach applies to any domain where complex physical systems need to be communicated clearly. Structural load paths, fluid system dynamics, environmental force modeling, infrastructure behavior under load.
