The figure 14.8 (b) provides a clear idea about wired and unwired technique used in visual effects.

Figure 14.8(b): Wired and Unwired Techniques of Visual
Effects

The following are the types of visual effects:
1. Rotoscoping: Rotoscoping is a method patented by Max Fleischer in 1917. In this method the
animators trace live action movements frame by frame. Then the source film is directly copied by
using the actor’s outlines and this is changed to animated drawings of a live environment. It is a
systematic method of isolating specific objects from the photographic plates. When a VFX shot is
not filmed on an appropriate background then the background is created with the help of
rotoscoping technique by digitally cutting the foreground of the actors frame by frame.

The Lord of the Rings is an example for Rotoscoping method.

The figure 14.9 depicts how the unwanted objects in a shot are made invisible by employing
rotoscoping, painting, and cloning methods.
