Beginner’s Guide to Animation Techniques

A Brief History of Animation

Breathing life into fixed static images and objects through the process of animation is one of the most magical and entertaining of art forms. Although the rudiments of animation date back to paleolithic cave paintings; it could be said the emergence of the film industry and the efforts of Walt Disney did for the art of animation what animation initially did for drawings: they gave them life. For the first time ever, eager audiences could experience with their very own eyes, the imaginations of artists shared through a medium which could educate, as well as entertain the masses.

The essence of animation was in fact ushered into the 19th century when in 1868, John Barnes Linnett patented the “Flip Book.” Known also as a “Flick Book” or “Kineograph” the viewer holds in one hand a relatively small picture book and literally “flips” through the book with the other by pressing the thumb against the pages while slightly bending the paper back. Utilizing persistence of vision to create an optical illusion, the eye perceives continuous motion from a series of near exact, yet progressively variating drawings. In 1912, one of the founders of the Gestalt school of thought, Max, Wertheimer named this illusion the “Phi Phenomenon.”

Somewhat of an artistic hybrid—half book and half movie, this perception of motion would go on to form the foundation of Hugo Munsterberg’s theory of film.

 

TYPES OF ANIMATION

As the entertainment industry utilized the benefits of scientific advancement in the 20th and 21st centuries, the field of animation underwent major changes and developments.  In the 20th Century, most animation was “classical” or “traditional.” With the advent of sophisticated technologies, various phases of development led to an abandonment of the hand-drawn image and the emergence of sophisticated computer-generated imagery or “CGI’s.” Animation no longer depended on the artist’s drawing skill, but rather their mastery of animation software and programming techniques. 

Traditional Animation

Before the emergence of mechanization within the realm of art, classical animation was referred to as “cel animation” or “hand-drawn.” As the latter term suggests, each figure or object was drawn by the artist in minute stages of movement. Each of these drawings was done on an acetate sheet or “cel.”

This is the animation one finds in the flip-book. By combining speed in viewing and minute drawing changes, it appears that movement is occurring. However, motion is an optical illusion, or as mentioned earlier, resulting from the pi phenomenon.

When contemplating the amount of effort and precision required for each image; one can accurately deduce the process as time consuming, laborious and costly. Since the art of animation was initially promulgated by the entertainment industry, profit-driven business executives were primed for welcoming the advent of less expensive techniques.

Stop-Motion Animation

The basic theory of traditional animation is utilized in stop-motion animation, however what is animated shifts from something hand-drawn to an object made of any number of materials; clay, wood, plastic, glass and paper; just to name a few. The “Gumby Show” is an example of one popular television show created with stop-motion animation. In this technique, the object(s) is photographed at various stages of nearly imperceptible alterations. When shown in rapid succession, the illusion of independent movement is created when in fact, there was none, absent the animator’s continuous change in placement. As entertaining as these creations were and are to audiences of all ages, as with the traditional mode of hand-drawn animation, the process proved to be labor-intensive, expensive and therefore, is rarely used.

Digital Animation

While “digital” was once a term referring to mysterious leading-edge devices, today it is a household adjective used to describe a plethora of items and processes. Digital animation is the most cost-effective and widely used method of producing animation for any number of purposes and is applied to both 2D and 3D projects. Computer-generated images (CGI’s) are constructed on a computer monitor, a process also referred to as modeling. For 2D animation, traditional animation theory is applied via key frames with layering. Movement is generated by automated computer calculations which “tween” or “morph” the object of animation, creating varying frames which are then rendered as needed.  

As you might have guessed, 3D animation is a bit more complicated. As before, the animator begins by creating a model on the computer. The modeling process can be done in several various ways. Objects are modeled via skeletons or a polygon mesh which serve to create visual dimensions to the subject matter. The model often resembles a marionette or puppet with strings.

 

Additional 3D Modeling Techniques

Photorealistic 3D Rendering

This digital art form creates life-like images which can be used for medical, scientific, entertainment, architectural, educational—as well as many other purposes. The key to this method is realism and true-to-life likeness, often despite preposterous settings and circumstance. You often find this technique used in films which depict events such as underwater travel, airplane stunts, acts of God or other cataclysms. However, it is also used for accident reconstruction, creative advertising and other more general depictions.

Cel Shading

Almost a “2 steps forward and 1 step back” method, cel shading or flat-shading takes a 3D model and restricts shading colors and tints to make the image appear flatter—much like traditional animation. Although not a widely-popular choice in the film and television industry, it is frequently used in the gaming industry.

Motion Capture

You might think of motion capture as taking the polygon mesh figure described above and supercharging or infusing it with realistic and lifelike movement. One of the most popular animation techniques in the film, television and gaming industries today, these super-human or ultra-lifelike mobilized subjects are produced when computer software and animator skill combine to create movement by coinciding the model’s “points” with the dynamics of actual movement.

 

In Conclusion

Whether you have dabbled in any or all the techniques mentioned above; or if you are engaging yourself with the topic for the first time, the world of animation is one of intrigue, expansion and cutting-edge technology. As an artist, you will need to have passion for the fields of design animation and computer graphics, as well as be willing to patiently “learn the ropes” so to speak. However, you are embarking on an industry which was founded, in some respects, by one of the most revered artists of all time, Walt Disney. And as he said, “Animation offers a medium of storytelling and visual entertainment which can bring pleasure and information to people of all ages everywhere in the world.”
