Rotoscoping has often been used as a tool for visual effects in live-action movies. By tracing an object, the moviemaker creates a silhouette (called a matte) that can be used to extract that object from a scene for use on a different background. While blue and green screen techniques have made the process of layering subjects in scenes easier, rotoscoping still plays a large role in the production of visual effects imagery.
There are two categories of rotoscoping in viusal effects.First is “VFX ROTOSCOPING” where we only focus on the outer areas and not to worry about the inner part of the object because we don’t need to create a fake depth for our scene.But if we want to create a fake depth to our movie which looks virtual realistic on screen.This technique is known as “STEREOSCOPING”and This type of movies are often shoot with the normal cameras and after shooting we generate the depth map for movie at post production where we need to create a depth map by manually tracing the scene on software through ROTOSCOPING process this kind of rotoscoping is called “STEREOSCOPING ROTOSCOPE”but the tasking for this type of rotoscoping is not too easy because we have to focus on the inner and outer part of an object.Stereoscopic movies are nowadays on demand,and market has launched stereoscoping cameras where it will automatically capture the scene and provide the depth map for stereo conversion.But in terms of rotoscoping depth map will created by manually.and tasking will be different from vfx rotoscoping.
