Technology Overview

The animation process is described in more detail below.

1. A camera person moves the camera (or a camera like object) with his/her/its body freely in space ­or with any of the pre­existing rigs for maneuvering a camera. This could be in a performance space or directly on the set of a stop­-motion animation.

2. The rotation and position of the camera is captured through pre­existing motion capture or camera extraction technologies.

3. The motion­ capture measurements are then scaled and manipulated virtually in Cartesian space to match the scale of a physical 3D set. If there is no scale shift ­ then this step only involves registration of the recorded movement with the robotic movement in the following step.

4. A motion control rig moves a camera around a stop-motion set, in small frame­-by­-frame increments,­ allowing an animator to execute a stop­-motion animation in front of a camera that seems to be held and manipulated by a human.

 

 

Advantages

• Camera movement is limited in stop-motion animation because motion control systems are limited in the design of the human control interfaces. Existing methods require a premeditated concept for camera movement, and do not rely on the expressive qualities human gesture and performance.

• The method of performing a hand-held camera motion gesture for a stop-motion performance allows the cinematographer to perform as an expressive and responsive character in the resulting film.

This method allows direct control of camera movement and results in a more expressive performance of the camera than existing methods of using human control interfaces.
