2. Motion Tracking: In the motion tracking technique, the movements are made on the camera.
While filming the 2-D/3-D, software is integrated with the CG elements and merged with the
original shot to generate a fine motion tracking process and get realistic and integrated visual
effects.
The figure 14.10 depicts motion tracking, where the CG elements are integrated with the original shot.

3. Stereoscopy: Stereoscopy is also known as stereoscopic or 3-D imaging. This technique is used to
create an illusion of depth in an image by presenting two separate offset images, one towards the
right and the other towards the left of the viewer’s eye. The two, 2-D off-set images are merged in
the brain to provide the depth of perception of 3-D image. A high level of precision involved in the
creation of the image provides images with the best visual impact. The Figure 14.11 depicts the
stereoscopic conversion from 2-D to 3-D.

The listed points are required to follow the strategies used in additional visual effects:
1. To have the viewer wear eyeglasses to combine separate images from two offset sources.
2. To have the viewer wear eyeglasses to filter offset images from a single source separated to each
eye.
3. To have the light source split the images directionally into the viewer's eyes (no glasses required).
