In the field of animation, professionals distinguish between two primary roles for technology in the production process.1

Computer-Assisted Animation

Computer-assisted animation utilizes technology to streamline and facilitate specific stages of the traditional, labor-intensive production process. In this approach, computers are used to automate tasks such as moving a rostrum camera or generating the "in-between" drawings required for full animation. Essentially, it acts as a digital aid to enhance or modify work that may have been initiated through traditional hand-drawn methods.12

Computer-Generated Animation

In contrast, computer-generated animation creates imagery directly through mathematical or computer language. Rather than relying on traditional photography or manual drawing, this method involves digitizing figures—such as three-dimensional objects—into computer terms. Once digitized, the computer can generate and display sequences that simulate complex motion, rotation, or movement through space.12

While both methods fall under the umbrella of computer animation, the fundamental difference lies in whether the computer is assisting a traditional workflow or serving as the primary engine for creating the imagery itself.1
