3Danimation is a technique that uses computer graphics to bring characters, objects, and other props closer to life. Through 3D animation, the characters and objects appear to move through three-dimensional space.

In 3D animation, the animator can produce stunning and fluid animations that are closer to life, more in-depth, and seem to practically leap off the screens. Since a 3D animation can be rotated and moved in a three-dimensional space, the movement seems naturally occurring.

William Fetter is said to be the first person who developed a real 3D image of the human form. The earliest pioneers of animation also include John Whitney. Initially, the uses were more focused on scientific and research purposes. But, courtesy of Dr Thomas Calvert, the creative aspect paved its way to animation as well.

Jurassic Park in 1993 had the audience in awe of the realistic dinosaurs. The 3D animation techniques today are way ahead which is why Jurassic Park (1993) might seem average-but back then, it had the audience hooked to the life-like 3D animation.

It was only by the late 1980s that photorealistic 3D began appearing in film movies. In 1995, Pixar released Toy Story. Toy Story was a defining movie; gaining huge recognition and appreciation, the first completely computer-generated movie made rounds across the globe.

Today, 3D animation is a preferred choice (or an obvious choice). Businesses use it to build better brand images. Above all, 3D animation has overcome limitations-it has made everything achievable; a possibility.

The difference between 2D and 3D animation is their depth. Where 2D objects are drawn on a two-dimensional (x-axis and y-axis) flat space, 3D brings in another dimension. Unlike 2D, 3D animation ensures depth through the z-axis.

3D or three-dimensional animation has more depth and is closer to reality. They are much more engaging and intriguing for the users. 2D animation is the oldest form of animation which still enjoys the cartoonish factor in the animation. They are simple and easier to produce if compared to 3D.

Similar to traditional animation, 3D animation is a tactic to trick the human eye. It is an illusion created by a series of fast-paced, consecutive images. 3D animation has become popular over time because the audience loves seeing life-like films, or videos.

Coupled with ease and a faster pace to use, 3D animation results in images that are extremely life-like. The product is engaging and more visually appealing so its use has become more frequent. From education to the military, 3D animation has proven itself as a smooth, engaging, and eye-catching solution. Its use is observed in advertising, video games, films, TV shows, architecture, business, medicine, technology prototyping, and many other fields.

Injecting life, depth, and detail to mere objects, the possibilities with 3D animation are limitless. Its use has shown an insane surge as it guarantees improved user experience, high-definition content, and real-time animations. It has become one of the most popular and celebrated techniques of filmmaking.

The immense possibilities of 3D animation have created its various uses in the global and local market. Today, businesses choose 3D animation to build an impressive brand image. Hence, 3D animation continues to be on a rise.

The earliest 3D animation technique is the stop-motion technique. Individual frames are prepared by the animator which is then combined and played at a fast speed to create a video. Approximately 10 to 12 frames are played per second to come up with a video.

The Stop-motion technique is a strenuous and time-consuming technique but, it creates intriguing and fun to watch videos. Some of the types of stop-motion are claymation, computer-generated stop-motion, and pixilation.

As the name suggests, claymation uses clay (or plasticine objects) as models. Computer-generated stop-motion uses computer-generated images and pixilation utilizes people instead of any other prop. The Stop-motion technique relies heavily on the frame-by-frame technique to demonstrate the technicalities or processes of a product or service.

Stereoscopic 3D videos raise the bar higher by providing in-depth illusion. Viewers use additional support like special glasses to further experience different views. Since the rendering is done in two halves, an illusion of depth is added to the image.

CGI cutout animated videos are an old but simple technique to explain complex concepts. Using cutouts from paper, cards, stiff fabric, or photographs. CGI cutout animated videos demonstrate information in the simplest manner.

In this type of animation, objects and characters are cut out of paper and connected together to form the whole. This animation technique uses pre-cut shapes from paper, cards, stiff fabric, or photographs and moves them at a speed to give off the illusion of movement. These precut shapes are then connected by a pivot point to create an independent piece of the body.

These days, the switch from paper-cut materials to scanned images can be observed. Specialized computer software is used to come up with high-quality animated videos. South Park is an excellent example of CGI cutout animated cartoon series.

Digital 3D animation has allotted another dimension to a flat two-dimensional image. Incorporating polarization, digital 3D has redefined animation techniques. Polarized images and polarized 3D glasses are used by the viewers to experience a different reality.

3D movies are created using the digital 3D technique. The infamous 3D glasses are required to fully experience 3D movies. You might have come across digital 3D images on the internet; these images can be seen differently by different viewers. They are an illusion to trick viewers. Different artistic effects are added to depict illusion in these 3D images.

Autostereograms have repeating patterns on a flat two-dimensional image. When a person focuses on a specific point and lets the eyes relax, a 3D image can be noticed. Autostereograms allow viewers to experience 3D images with the naked eye.

The first phase in 3D animation requires an animator to create 3D objects within a virtual space. The engineer or artist uses a specialized 3D software or 3D modeling tool to create models on a computer.

Using a 3D modeling tool is similar to sculpting from clay-and shaping objects the way you want them. Backed with light, texturing, reflections, and shadows, 3D models are created through a chosen software. Polygons and quads are manipulated and perfected to achieve a model-which is later sent to animation and rendering stages.

This phase refers to placing and animating the objects and characters within a scene. After the modeling phase where characters are rigged and a skeleton is prepared, this stage involves keyframing (animating the beginning and final form of an object) and placing the objects in a particular set. In the layout phase, objects are positioned within a particular designated set.

Rendering completes the entire procedure of 3D animation. It is one of the most significant steps of 3D animation. All the files of colour, lighting, character movement, texturing, etc. are combined to give off the final product.

Rendering plays a vital role in the results that are achieved. This stage heavily relies on the CPU and is a memory-intensive process. It takes up hours to render. The rendering depends on the complexity of shapes, colours, and special effects added to the frame. A typical example suggests that a 3-minute animation might take up to 6 hours to render.

Apart from these three phases, the lengthy process of 3D animation also involves various sub-steps: conceptualizing and storyboarding, 3D modeling, texturing, rigging, animation, lighting, rendering, adding special effects, music, and then the outcome. It is done using a special 3D modeling software, though there is specific 3D rendering software available as well.

3D animation has become quite the advertising and marketing leader in the past decade. Considering its worthwhile impact and benefits, 3D animation has become especially popular. Here are some of the many advantages of 3D animation.

As the animations are closer to reality, the audience gets intrigued and instantly wants to know more about the product or service. This is exactly why the 3D animation technique is especially employed in advertisements and promotions.

Fluid, interactive and smooth animations create interaction opportunities with the viewers. Details, swift movements, and crisp imagination are easily reflected through 3D animation and the audience enjoys it.

3D animation requires expensive technology, a large labour force, and extensive working hours. 3D animation technique costs much more than 2D. Further, it is a complicated and extremely technical animation that requires experienced 3D animators to come up with smooth, high-quality animations. Hence, the costs are undoubtedly higher.

An alarming situation with 3D animation is that not all animators are pro at all the procedural stages for 3D. With 3D, different animators are assigned different tasks. For instance, one animator might be responsible for texturing while the other might be in charge of the character animation or rigging.

Since there are different stages to the entire procedure of 3D, it is undoubtedly a labour-intensive technique. It is highly unlikely to have an animator that can do it all. 3D requires a greater labour force.

The entire procedure of 3D animation is extremely technical and complex. It lacks simplicity and requires experienced professionals at work to produce high-quality animated videos. With larger labour at work, 3D animation involves multiple complex techniques.

Unlike 2D animation, 3D animation ensures greater detail and accuracy which means a lack of simplicity. 3D animation has normalized perfect manipulation and creation of characters that the traditional animation techniques seem ordinary.
