In 1965, Michael Noll made a significant mark in the history of animation with his groundbreaking film "Computer Ballet," which was the first computer animation to feature a human figure. This film not only captivated audiences with its depiction of a ballet but also demonstrated the technical intricacies of early 3D computer animation.
Noll, a computer expert, transformed his vision of a computer-generated ballet into a detailed and sophisticated computer program. The process began with him setting up instructions to draw the stage using an automatic device designed to produce images. This complex program was then stored on magnetic tape, a crucial medium for data storage at the time. The magnetic tape transmitted the instructions to a cathode ray tube (CRT) display, where the actual animation was brought to life.
The creation of the program was a meticulous task. Noll designed a program that defined the precise movements of a human figure, effectively translating his artistic vision into executable computer instructions. The first part of this program set up the stage on the CRT display, which acted as a dynamic canvas, drawing each frame of the ballet in sequence.
Once the program was completed, it was transferred onto magnetic tape. This tape was essential for carrying the program's instructions to the automatic drawing device, which then generated the images on the CRT. The CRT display produced each frame slightly different from the last, mimicking traditional animation techniques to create the illusion of continuous movement.
Noll’s attention to detail didn't stop at generating the images. He meticulously verified the accuracy of each image displayed on the CRT, ensuring that the animations were smooth and visually correct. This step was crucial for maintaining the quality of the animation.
The filming process was equally meticulous. An ordinary film camera was positioned in front of the CRT to photograph each image frame by frame as it appeared on the tube. This manual process was essential for capturing the entire animation sequence accurately. To expedite the workflow, the setup included a developing tank built into the apparatus, allowing the film to be processed immediately after each frame was captured. This rapid development was key to maintaining the integrity of the animation sequence and ensuring that no frames were lost or damaged.
"Computer Ballet" was not just about the final product but also about demonstrating the meticulous technical process behind early computer animation.
This pioneering work offered a glimpse into the future of digital art and animation, showcasing the incredible capabilities of early computer technology and setting the stage for the sophisticated animations we enjoy today.
