Animation 2D & 3D

2D-3D animation is manifested by combining traditional drawing techniques with advanced digital technologies, generating animated images that can be two-dimensional or three-dimensional. While 2D animation uses sequential drawings to suggest movement, 3D animation involves digitally modeling characters and objects in a virtual space, giving depth and realism to scenes.

History

The history of 2D and 3D animation is a fascinating journey, reflecting both technological progress and the evolution of artistic expression. Animation was originally a primitive form of entertainment, found in the sequential drawings of ancient civilizations or in optical toys of the 18th and 19th centuries, such as the thaumatrope, zoetrope and praxinoscope. These devices used successive images to create the illusion of movement, thus laying the foundation for modern animation.

In the 20th century, 2D animation began to develop rapidly with the advent of film. A landmark moment was in the early 1900s, when Émile Cohl made the first animations with simple drawings, sequenced to create movement, such as " Phantasmagorie " (1908), considered one of the first 2D animated films in history. Soon after, the animation industry began to develop, and Walt Disney Studios played a key role in revolutionizing this art. In 1928, Disney released " Steamboat Willie ," the first animated film synchronized with sound, which introduced the famous Mickey Mouse. In 1937, "Snow White and the Seven Dwarfs ," the first animated feature film produced by Disney, demonstrated how powerful 2D animation could be in creating emotional and captivating stories.

Over the decades, colorization technologies and animation techniques continued to evolve, improving the visual and technical quality of 2D productions. During the 1950s and 1960s, animation became increasingly popular in film and television, with iconic series such as " Looney Tunes " and " Tom and Jerry ," cementing themselves as a significant cultural fixture. Traditional 2D animation became synonymous with hand-drawn frame-by-frame, a laborious process that required not only artistic skill, but also patience and precision.

However, in the 1980s, with technological advances and the advent of the personal computer, a new era in animation emerged: 3D animation . The first manifestation of this technology was the use of computer-generated graphics(CGI) to create simple sequences. Films such as " Tron " (1982) integrated the first CGI effects, suggesting the immense potential of 3D animation. But the turning point came in 1995, when Pixar, in collaboration with Disney, released "Toy Story" , the first full-length animated film made entirely using 3D techniques. The film impressed audiences with its realism, three-dimensional detail and fluidity of movement, thus redefining the animation industry.

Burton managed to create a unique, dark and charming world through innovative techniques that combine tradition and modernity in animation.

The work process

The 2D and 3D animation process involves a well-coordinated sequence of steps that transform initial ideas into complex and captivating animated images. It all starts with the conceptualization and development of the story , at which point the theme is established, the characters are created and the script is developed. At this stage, the visual style, color palette, and general atmosphere of the animation are also defined. Once the story is clarified, a storyboard is created , which is a series of sketches that describe the main scenes and actions of the film, helping to visualize the entire project.

In the case of 2D animation, the next step is to create key drawings , which define the main positions of the characters during movement. These drawings are complemented by other intermediate frames that give fluidity to the movements. Once completed, the drawings are digitized and colored, and the animation comes to life through a compositing process, in which the individual elements are combined to create the final scenes.

In 3D animation, the process first involves digitally modeling characters and objects , using specialized software to build three-dimensional shapes. After modeling, textures and materials are added to give realism to surfaces, and the characters are "endowed" with a virtual skeleton structure (rigging), which allows them to be animated. This is followed by the actual animation stage , where the characters' movements are created by placing them in different positions over time, to simulate natural actions. In some cases, motion capture technology is used , capturing the real movements of the actors and transposing them into the virtual space.

The final stage is rendering and post-production , where the animation is processed and special effects, lighting, and final color corrections are applied. This is followed by the addition of sound, music, and sound effects, which give depth and expressiveness to the scenes. This laborious and complex process requires meticulous attention to detail and close collaboration between animators, directors, sound designers, and other professionals to create a coherent and immersive visual experience.

Materials and tools

The materials and tools used in 2D and 3D animation vary depending on the techniques and style desired, covering both traditional and advanced digital tools. In classic 2D animation, hand-drawn, sketch paper, pencils, inks, and paintsare used , along with transparent sheets of celluloid on which individual frames were drawn and colored. This traditional technique, although less commonly used today, retains a special charm, giving the works a distinctive character. In addition, animation cameras were used to compose and combine animated frames, recording each drawing in an orderly sequence.

Nowadays, most 2D animations are made using specialized software , such as Adobe Animate, Toon Boom Harmony or TVPaint, which offer increased flexibility in creating drawings and applying visual effects. These digital tools replace the need for manual drawing on paper, allowing animation directly on graphics tablets, such as Wacom, and facilitating the coloring and compositing processes.

"When you make animation, you give yourself the freedom to invent new universes and redefine the laws of reality." – Chris Wedge

3D animation, on the other hand, relies almost exclusively on advanced digital tools , using programs such as Autodesk Maya, Blender, 3ds Max or Cinema 4D for modeling, rigging and animation. High-performance workstations are essential in this field, as the rendering and simulation processes require significant computational resources. Graphics tablets and high-resolution monitors are indispensable for precise modeling and texturing. In addition, motion capture equipment is used to capture natural movements , which records the real movements of the actors and transcribes them into the digital environment.

In both types of animation, sound and audio editing play a crucial role in the completion of the work, with audio processing programs being used to synchronize sound effects, voices, and music with the animated action. Thus, the combination of traditional and digital tools, between physical and virtual elements, contributes to enriching the creative process, allowing artists to bring to life complex and captivating animated universes.

Working techniques in 2D animation

Frame-by-frame drawing is the essence of traditional 2D animation. In this technique, each frame is drawn by hand, creating a fluid illusion of movement as the images are played back one after another. Every detail is thought out and drawn, giving the work a distinctive artistic texture where the animator’s gestures can be sensed. It is a meticulous and time-consuming process, but the result is worth the effort with a unique depth of movement. Classic Disney animated films used this method to bring memorable characters to life, while retaining the charm and energy of hand-drawn animation.

Cut-out animation is a time-saving alternative technique that uses predefined character parts or separate elements that are animated by rotating, moving, or resizing them. Instead of drawing each frame, the animator manipulates individual components of a character, such as arms or legs, to simulate movement. This method allows for greater efficiency in production, and is often seen in animated series such as "South Park," where the simplified style and visual humor are part of the show's distinctive characteristics.

Tweening involves creating keyframes for movement, and the software fills in the in-betweens to provide a smooth transition between movements. This is a technique commonly used in 2D digital animation, as it simplifies the process, reduces manual work, and streamlines production. Tweening allows for precise control of movement, making it a preferred option in modern animation for music videos and commercials.

Rotoscoping is a technique in which animated frames are drawn over live-action footage, providing a realistic representation of movement. In animation, rotoscoping is used to add subtle details and precise movement while maintaining the graphic character of the drawing. It is a method that combines the art of drawing with cinematic realism, being used in productions such as Richard Linklater's "A Scanner Darkly", where the rotoscoping style gives a unique aesthetic and an enigmatic atmosphere.

Motion graphics involves animating graphic elements to communicate a message or visually enhance a production. Commonly used in commercials, videos, and film intros, this technique emphasizes the movement of typography, shapes, and colors, creating dynamic and captivating compositions. Motion graphics is less focused on classic storytelling and more on visual impact, offering an effective solution for quickly and attractively communicating information.

Working techniques in 3D animation

3D modeling is the first step in creating virtual worlds, and is a fundamental technique in three-dimensional animation. Through modeling, objects and characters are built from polygonal structures, using specialized software such as Maya, Blender or 3ds Max. These models are created by adding and manipulating the points, edges and faces that make up the geometry of the object, providing a basis for animation. The modeling process allows the creation of simple structures, such as everyday objects, or complex shapes, such as detailed characters and fantasy creatures, thus establishing the skeleton of each animated scene.

Rigging is the technique of adding an internal "skeleton" structure to a 3D model, allowing animation through control of joints and deformations. This "skeleton" includes a series of virtual joints, which allow animators to manipulate the character's movements in a natural and believable way. Rigging allows the movement of the arms, legs, head, and other body parts to be defined, providing great flexibility in creating complex animations. This technique is crucial for detailed characters, such as those in animated films or video games, where every movement must be as realistic as possible.

Motion capture , also known as mock-up, involves recording the real movements of actors and transferring them to digital characters. Actors wear sensors or special suits that capture their movements, and the data is processed and applied to 3D models. This technique is used to add a high degree of realism and authenticity to animation, and is frequently used in action films, video games, and high-quality cinematographic productions. Motion capture allows the creation of natural and detailed movements that would be difficult to achieve manually.

Digital sculpting is used to refine and detail 3D models, adding fine textures and nuances. This process is comparable to traditional sculpting, but in a digital environment, where artists can mold shapes as if they were virtual clay, adding minute details. The technique is popular in character design, where complex facial expressions and realistic skin textures are required, as well as in creating special effects for films. Digital sculpting allows for exceptional precision, giving the freedom to add high-resolution details that enhance the final appearance of the model.

Physics and special effects simulations are essential techniques for adding realism to 3D animation. They involve the use of computer simulations to recreate natural phenomena, such as flowing water, burning fire, or the movement of textiles. Special effects contribute to the atmosphere of animated scenes, adding elements of realism or fantasy, and are frequently used to enrich digitally created universes. Whether it's a spectacular explosion or hair waving in the wind, these techniques enhance the visual experience and provide a sense of authenticity.
