Computer Animation in Movies

By James Goldstein


Computer animation is quickly becoming a normal addition to movies. They are now using it when they need to insert something in a scene that they don't have time to construct or build. They are also creating computer animated figures that look and act like they are moving and interacting with humans in the film.

Computer generated imagery, also know as computer animation is a process where images are solely created digitally on a computer. Software and programs have specially been written for these purposes. Computer generated imagery uses 3D and 2D images that you build yourself with special graphic programs. You will learn all about CGI while you are working toward your MFA degree online.

CGI was first used with 2D images in Westworld, introduced in 1973. 3D graphics were used in Futureworld in 1976 which was the sequel to Westworld. Tron in 1982 and The Last Starfighter in 1984 were the first two films to make heavier use of 3D computer graphics. The first actual 3D character was created by Pixar in its 1985 version of Young Sherlock Holmes.

The first 2D animations were created with the use of 2D bitmap graphics and 2D vector graphics. Other techniques combined in the process of making the 2D images included but weren't limited to tweening, interpolated rotoscoping, morphing and onion skinning. You will cover how to use all of these techniques while you are taking classes at the online film school.

The animator must first create a digital skeletal structure before he/she creates their 3D image. From this structure they can pose it, move it, give in skin, hair, fur or if it isn't a live object, they can create the simulation of water or fire. Special graphic software gives them all the tools they need to use these 3D dynamics.
