Prompt

Apply a motion capture visualization effect, rendering the subject as a smooth shaded digital double with small luminous tracking markers at visible articulation points and thin skeletal rig connections. Preserve natural posture, silhouette, and subtle asymmetries, with restrained wireframe accents and cool studio lighting. Keep the original subject and composition.

Identify

A digital figure adopts nuances of human movement.

Principle

Movement is measured, transferred to a digital skeleton1 and processed2.

Example

Gollum: The Two Towers, 2002.

Try it out

Compare the performance and the finished animation of a gesture.

Background

Wētā made significant progress in motion capture and character animation for Gollum. In later Hobbit productions, Andy Serkis and Martin Freeman were captured on set. Animators translated the performance into the digital character and augmented it with their work. The 2000s mark the widespread public visibility of such characters, while measurement techniques and digital motion research are considerably older.

Distinction

Motion capture does not produce a finished figure. Retargeting, correction, animation, anatomy, and rendering remain essential; not every visible facial expression originates directly from captured data.

Aftermath

A believable digital body combines performance, measurement, and animation.

Question

What does retargeting mean?

Show possible answer +

The transfer of captured movements to the differently proportioned digital skeleton of a figure.
