What is 3D?

In filmmaking, the term 3D can refer to two different things; it can refer to stereoscopic images or computer-generated images created with 3D software such as Blender, Autodesk Maya or SideFX Houdini.

Stereoscopic images are typically created by using two cameras to film the same scene from slightly different angles (usually a distance similar to the average distance between human eyes), which are then combined to create the illusion of depth. Stereoscopic images can also be created using software and extensive rotoscoping.

In order to view a 3D (stereoscopic) movie, viewers must wear special glasses that allow each eye to see a different image. This creates the illusion of depth and helps create a more immersive experience. While stereoscopic movies have been around for several decades, they have only become widely popular in recent years. Thanks to technological advances, filmmakers can now create more realistic and lifelike stereoscopic images than ever before. As a result, more and more people are enjoying the immersive experience of watching a “3D” movie.
